Full textAbstract:
Mushroom polysaccharides are a kind of biological macromolecule extracted from the fruiting body, mycelium or fermentation liquid of edible fungi. In recent years, the research on mushroom polysaccharides for alleviating metabolic diseases, inflammatory bowel diseases, cancers and other symptoms by changing the intestinal microenvironment has been increasing. Mushroom polysaccharides could promote human health by regulating gut microbiota, increasing the production of short-chain fatty acids, improving intestinal mucosal barrier, regulating lipid metabolism and activating specific signaling pathways. Notably, these biological activities are closely related to the molecular weight, monosaccharide composition and type of the glycosidic bond of mushroom polysaccharide. This review aims to summarize the latest studies: (1) Regulatory effects of mushroom polysaccharides on gut microbiota; (2) The effect of mushroom polysaccharide structure on gut microbiota; (3) Metabolism of mushroom polysaccharides by gut microbiota; and (4) Effects of mushroom polysaccharides on gut microbe-mediated diseases. It provides a theoretical basis for further exploring the mechanism of mushroom polysaccharides for regulating gut microbiota and gives a reference for developing and utilizing mushroom polysaccharides as promising prebiotics in the future.

Full textAbstract:
Mushroom polysaccharides are active medicinal compounds that possess immune-modulatory and anticancer properties. Currently, the mushroom polysaccharides krestin, lentinan, and polysaccharopeptides are used as anticancer drugs. They are an unexplored source of natural products with huge potential in both the medicinal and nutraceutical industries. The northern parts of Pakistan have a rich biodiversity of mushrooms that grow during different seasons of the year. Here we selected an edible Morchella esculenta (true morels) of the Ascomycota group for polysaccharide isolation and characterization. Polysaccharopeptides and polysaccharides from this mushroom were isolated using the green chemistry, hot water treatment method. Fourier transform infrared spectroscopy revealed the sugar nature and possible beta-glucan type structure of these polysaccharides. Antioxidant assays showed that the deproteinized polysaccharides have moderate free radical scavenging activity. These isolated polysaccharides exhibited good acetylcholinesterase (AChE) and butyryl cholinesterase (BChE) inhibition activities. Therefore, these polysaccharides may be valuable for the treatment of Alzheimer’s and Parkinson’s diseases. Further bioassays are needed to discover the true potential of M. esculenta polysaccharides for medicinal purposes.

Full textAbstract:
Oyster mushrooms are an interesting source of biologically active glucans and other polysaccharides. This work is devoted to the isolation and structural characterization of polysaccharides from basidiocarps of the cultivated oyster mushroom, Pleurotus ostreatus. Five polysaccharidic fractions were obtained by subsequent extraction with cold water, hot water and two subsequent extractions with 1 m sodium hydroxide. Branched partially methoxylated mannogalactan and slightly branched (1→6)-β-d-glucan predominated in cold- and hot-water-soluble fractions, respectively. Alternatively, these polysaccharides were obtained by only hot water extraction and subsequent two-stage chromatographic separation. The alkali-soluble parts originating from the first alkali extraction were then fractionated by dissolution in dimethyl sulfoxide (DMSO). The polysaccharide insoluble in DMSO was identified as linear (1→3)-α-d-glucan, while branched (1→3)(1→6)-β-d-glucans were found to be soluble in DMSO. The second alkaline extract contained the mentioned branched β-d-glucan together with some proteins. Finally, the alkali insoluble part was a cell wall complex of chitin and β-d-glucans.

Introduction. In connection with the acquisition of antibiotic resistance of pyogenic microbiota, the problem of topical (drug) treatment of wounds has become aggravated. Aim. Comparative in vivo evaluation of the medicinal properties of ointments prepared on the basis of some biologically active complexes from higher basidiomycetes. Materials and methods. Experimental ointments were obtained on the basis of melanins from the natural raw materials of the сhaga Inonotus obliquus and from its deep-liquid culture, total polysaccharides from the oyster mushroom Pleurotus ostreatus, as well as the melanin polysaccharide complex from these mushrooms. Melanins were obtained by alkaline hydrolysis. Melanin-containing ointments were prepared using two formulations of ointment bases (the ointment base included saline, vaseline oil, emulsifiers T-2 and Tween-60, in the second case — saline, lanolin as an emulsifier and vaseline) in the first case. Total polysaccharides were obtained by 96% ethyl alcohol precipitation from an aqueous extract of a fungal homogenate heated in a boiling water bath for 12 h, followed by purification from fractions insoluble in distilled water. Melanin-polysaccharide-containing ointments were prepared on the basis of melanins from the natural raw materials of the сhaga Inonotus obliquus and from its deep culture, total polysaccharides from the oyster mushroom Pleurotus ostreatus, the ratios in the ointment formulations being (1:1 and 1:2). The ointment base of polysaccharide-containing and melanin-polysaccharide-containing ointments was similar to the specified second formulation. The wound healing efficacy of the ointments was evaluated in eight groups (20 mice each) of healthy non-inbred mice of both sexes, weighing 17–19 g, of the ICR colony of the State Scientific Center for Virology and Biotechnology Vector. The control group was a group of mice, in the treatment of which Levomicon-TFF reference ointment was used (20 mice in the group). The treatment of mice was continued until their incised skin wounds healed. The motor activity, appetite, and dynamics of wound healing were evaluated daily in mice of all groups, the change in their body weight was assessed every three days, and a histomorphological study of the incised skin wound was performed. The areas of wounds, the percentage of reduction in the area of wounds, the rate of wound contraction, and the rate of wound healing were determined. Results. It was shown that the components of the ointment bases of the two tested ointment formulations, melanin from the natural raw materials of the сhaga and from its deep-liquid culture, the total polysaccharides of the oyster mushroom, as well as the melanin polysaccharide complexes of these mushrooms, do not have toxicity for experimental animals in the concentrations of the tested ointment formulations. Ointments containing melanins from natural raw materials and deep-liquid culture of the сhaga Inonotus obliquus have similar regenerative properties, ointments with a fivefold increase in the content of these melanins, polysaccharide-containing and melanin-polysaccharide-containing ointments, have provided significantly accelerated wound healing in experimental animals. At the same time, the development of granulation tissue in the wound and the replacement of the wound defect in the skin with stratified squamous epithelium as early as on the 12th day in these groups of animals, were demonstrated in comparison with mice of the control group treated with the reference ointment Levomicon-TFF. The epidermal defect in animals of the control group was eliminated only on the 21st day. Conclusion. Ointments containing melanins from the natural raw materials of сhaga and from its deep-liquid culture, polysaccharides from the oyster mushroom, as well as a complex of these substances from these mushrooms, are superior in wound healing effectiveness, as compaired to the control ointment Levomicon-TFF, and can be considered as promising for topical treatment of wounds.

"The Effects of Major Mushroom Bioactive Compounds on Mechanisms That Control Blood Glucose Level." Journal of Fungi 7, no. 1 (January 16, 2021): 58. http://dx.doi.org/10.3390/jof7010058.
Full textAbstract:
Diabetes mellitus is a life-threatening multifactorial metabolic disorder characterized by high level of glucose in the blood. Diabetes and its chronic complications have a significant impact on human life, health systems, and countries’ economies. Currently, there are many commercial hypoglycemic drugs that are effective in controlling hyperglycemia but with several serious side-effects and without a sufficient capacity to significantly alter the course of diabetic complications. Over many centuries mushrooms and their bioactive compounds have been used in the treatment of diabetes mellitus, especially polysaccharides and terpenoids derived from various mushroom species. This review summarizes the effects of these main mushroom secondary metabolites on diabetes and underlying molecular mechanisms responsible for lowering blood glucose. In vivo and in vitro data revealed that treatment with mushroom polysaccharides displayed an anti-hyperglycemic effect by inhibiting glucose absorption efficacy, enhancing pancreatic β-cell mass, and increasing insulin-signaling pathways. Mushroom terpenoids act as inhibitors of α-glucosidase and as insulin sensitizers through activation of PPARγ in order to reduce hyperglycemia in animal models of diabetes. In conclusion, mushroom polysaccharides and terpenoids can effectively ameliorate hyperglycemia by various mechanisms and can be used as supportive candidates for prevention and control of diabetes in the future.

Potravinarstvo Slovak Journal of Food Sciences 16 (May 10, 2022): 258–70. http://dx.doi.org/10.5219/1755.
Full textAbstract:
It is possible to maximise the consumer properties of grown fruit and vegetable products, significantly reduce their losses during the life cycle, and satisfy the public demand for products ready for consumption by using different preservation methods, particularly freezing. It has been found that the freezing of mushrooms without pretreatment does not provide a high-quality finished product. It justifies the expediency of mushroom pretreatment before freezing to stabilize their consumer properties. The inhibition effect of high temperatures on the oxidoreductase activity has been confirmed, ensuring the high preservation of cultivated champignons' natural color and consistency. A quasimetric assessment of the quality of quick-frozen cultivated mushrooms was performed, and the optimal heat treatment parameters were determined. Before freezing, blanched mushrooms' efficiency with polysaccharides has been scientifically proved. Rational concentrations and types of polysaccharides for mushroom processing have been determined. It has been established that blanching champignons in 0.1% citric acid solution followed by xanthan gum (0.2%), guar gum (0.1%), and lamidan (0.1%) processing ensure stability of consumer properties of quick-frozen semifinished products made of cultured champignons. After defrosting, they have an attractive appearance, natural light brown colour, elastic consistency, well-expressed mushroom flavour, and harmonious taste.

The article is devoted to the study of polysaccharides isolated from the basidiomycete raw material I. hispidus and studying their physical and chemical properties. Water-soluble polysaccharides were isolated from mushroom raw materials by the method of sequential water extraction and the yield was 9.44%. Polysaccharides were separated into neutral fractions by ion exchange chromatography and purified from proteins and peptides. During the separation process, it was determined that the polysaccharide sample consisted of homogeneous polysaccharides, while the carbohydrate content of the purified polysaccharide sample was 99.4%. The carbohydrate composition of polysaccharides was determined, it was found that the polysaccharide consists mainly of glucose residues and contains minor amounts of fructose and rhamnose residues. Molecular weight and molecular weight distribution were determined by size exclusion chromatography. The Mw of the polysaccharide sample obtained was 18.7 kDa, the polydispersity index was 1.3. The results of IR-, 1H- and 13C NMR spectroscopic studies have shown that the polysaccharide, according to its structural characteristics, belongs to the β-glucan type polysaccharide having β-(1,3) and β-(1,6)-glycosidic bounds.

Mushrooms have been valued as food and health supplements by humans for centuries. They are rich in dietary fiber, essential amino acids, minerals, and many bioactive compounds, especially those related to human immune system functions. Mushrooms contain diverse immunoregulatory compounds such as terpenes and terpenoids, lectins, fungal immunomodulatory proteins (FIPs) and polysaccharides. The distributions of these compounds differ among mushroom species and their potent immune modulation activities vary depending on their core structures and fraction composition chemical modifications. Here we review the current status of clinical studies on immunomodulatory activities of mushrooms and mushroom products. The potential mechanisms for their activities both in vitro and in vivo were summarized. We describe the approaches that have been used in the development and application of bioactive compounds extracted from mushrooms. These developments have led to the commercialization of a large number of mushroom products. Finally, we discuss the problems in pharmacological applications of mushrooms and mushroom products and highlight a few areas that should be improved before immunomodulatory compounds from mushrooms can be widely used as therapeutic agents.

Full textAbstract:
Diabetes mellitus is a complex illness in which the body does not create enough insulin to control blood glucose levels. Worldwide, this disease is life-threatening and requires low-cost, side-effect-free medicine. Due to adverse effects, many synthetic hypoglycemic medications for diabetes fail. Mushrooms are known to contain natural bioactive components that may be anti-diabetic; thus, scientists are now targeting them. Mushroom extracts, which improve immune function and fight cancer, are becoming more popular. Mushroom-derived functional foods and dietary supplements can delay the onset of potentially fatal diseases and help treat pre-existing conditions, which leads to the successful prevention and treatment of type 2 diabetes, which is restricted to the breakdown of complex polysaccharides by pancreatic-amylase and the suppression of intestinal-glucosidase. Many mushroom species are particularly helpful in lowering blood glucose levels and alleviating diabetes symptoms. Hypoglycaemic effects have been observed in investigations on Agaricussu brufescens, Agaricus bisporus, Cordyceps sinensis, Inonotus obliqus, Coprinus comatus, Ganoderma lucidum, Phellinus linteus, Pleurotus spp., Poria cocos, and Sparassis crispa. For diabetics, edible mushrooms are high in protein, vitamins, and minerals and low in fat and cholesterol. The study found that bioactive metabolites isolated from mushrooms, such as polysaccharides, proteins, dietary fibers, and many pharmacologically active compounds, as well as solvent extracts of mushrooms with unknown metabolites, have anti-diabetic potential in vivo and in vitro, though few are in clinical trials.

The crude polysaccharides from Armillaria mellea were obtained with an ultrasound assisted enzymatic extraction and ethanol precipitation. Two polysaccharide fractions were obtained by ethanol precipitation, which were named AMP-1 and AMP-2. The results of the monosaccharide composition analysis indicated that AMP-1 was composed of mannose, rhamnose, glucose, galactose, arabinose and fucose and that AMP-2 was composed of mannose, rhamnose, glucose, galactose and fucose. Glucose and galactose were the main monosaccharide fractions. The protein and nucleic acid contents in AMP-1 and AMP-2 were detected by using ultraviolet and infrared spectroscopy. The bile salt-binding capacities of the polysaccharide samples were studied in vitro. In comparison with lentinan (LP), AMP-1 and AMP-2 showed increased bile salt-binding capacity. AMP-1 showed the highest binding capacity against all the bile salts. The findings presented in this study highlight the potential of the A. mellea polysaccharides as a natural hypolipidaemic agent.

Full textAbstract:
Selenosugars are a group of sugar derivatives of great structural diversity (e.g., molar masses, selenium oxidation state, and selenium binding), obtained as a result of biosynthesis, chemical modification of natural compounds, or chemical synthesis. Seleno-monosaccharides and disaccharides are known to be non-toxic products of the natural metabolism of selenium compounds in mammals. In the case of the selenium-containing polysaccharides of natural origin, their formation is also postulated as a form of detoxification of excess selenium in microorganisms, mushroom, and plants. The valency of selenium in selenium-containing polysaccharides can be: 0 (encapsulated nano-selenium), IV (selenites of polysaccharides), or II (selenoglycosides or selenium built into the sugar ring to replace oxygen). The great interest in Se-polysaccharides results from the expected synergy between selenium and polysaccharides. Several plant- and mushroom-derived polysaccharides are potent macromolecules with antitumor, immunomodulatory, antioxidant, and other biological properties. Selenium, a trace element of fundamental importance to human health, has been shown to possess several analogous functions. The mechanism by which selenium exerts anticancer and immunomodulatory activity differs from that of polysaccharide fractions, but a similar pharmacological effect suggests a possible synergy of these two agents. Various functions of Se-polysaccharides have been explored, including antitumor, immune-enhancement, antioxidant, antidiabetic, anti-inflammatory, hepatoprotective, and neuroprotective activities. Due to being non-toxic or much less toxic than inorganic selenium compounds, Se-polysaccharides are potential dietary supplements that could be used, e.g., in chemoprevention.

Full textAbstract:
Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm mushroom contains bioactive compounds with both antimicrobial and prebiotic properties, which are distributed in the mushroom mycelium, fruiting body, and spent substrate. The mushroom is rich in nondigestible carbohydrates like chitin and glucan, which act as prebiotics and support the growth and activity of beneficial gut bacteria, thereby maintaining a healthy balance of gut microbiota and reducing the risk of antibiotic resistance. The bioactive compounds in P. ostreatus mushrooms, including polysaccharides (glucans, chitin) and secondary metabolites (phenolic compounds, terpenoids, and lectins), exhibit antibacterial, antiviral, and antifungal activities. When mushrooms are consumed, these compounds can help preventing the growth and spread of harmful bacteria in the gut, reducing the risk of infections and the development of antibiotic resistance. Nonetheless, further research is necessary to determine the efficacy of P. ostreatus against different pathogens and to fully comprehend its prebiotic and antimicrobial properties. Overall, consuming a diet rich in mushroom-based foods can have a positive impact on human digestion health. A mushroom-based diet can support a healthy gut microbiome and reduce the need for antibiotics.

It is well-known that the utilization of mushrooms as therapeutic agents is not new. Over the past years, they have been used by local individuals as food, as well as medicines, throughout the world. Nowadays, mushrooms are excessively used in the medicine, pharmacy, food, and fermentation fields as well. Wild mushrooms are of particular interest, especially Trametes versicolor (commonly known as turkey mushrooms) due to their various uses in the food and pharmaceutical industries. They represent not only a huge storehouse of vitamins, minerals, and dietary fiber, but they are also an important source of bioactive polysaccharides. They are widely used in traditional oriental therapies. The fruiting bodies are used in the preparation of health tonics and tea. The present review is necessary to explore more about this mushroom-like classical taxonomy, morphology, nutritional value, bioactivity, various health attributes, mechanism of bioactive components against various diseases, and food applications. The influence of processing processes on the nutritional properties and bioactivity of the fungus is discussed. Potential bioactive components promising health attributes of Trametes versicolor are extensively described. Additionally, several in vivo and in vitro studies have demonstrated the beneficial effects of polysaccharopeptides (PSP) and Polysaccharide-K (PSK) on the aspects related to immune function and inflammation, also presenting an anticancerous effect. Moreover, PSP and PSK were successfully described to decrease several life-threatening diseases. The potential food applications of Trametes versicolor were detailed to signify the effective utilization of the mushroom in functional food formulation.

Full textAbstract:
The use of products obtained from fungi (particularly mushrooms) has increased lately due to their broad applicability in different scientific and industrial fields. The genus Trametes comprises a group of white rot producing ligninolytic fungi, with medicinal properties, biotechnological importance and environmental applications. One of the most potentially useful species is T. versicolor, formerly known as Coriolus versicolor or Polyporus versicolor. Also known as Yun Zhi in China, is a fungus species belonging to the class Basidiomycetes, which has a widespread application as medicinal mushroom, and is also consumed as food and tea infusion. It also produces extracellular enzymes such as laccases, manganese peroxidases, lignin peroxidases and H2O2 producing oxidases. These enzymes are capable of degrading such complex compounds as lignin, as well as certain industrial contaminants. T. versicolor is one of the first higher fungi to be used in the production of an approved medicine. In effect, polysaccharides like Polysaccharide Krestin and Polysaccharide Peptide obtained from the liquid fermentation of its mycelium, exhibit anticarcinogenic properties, and are therefore used for preparing several pharmaceutical products. Both polysaccharides are highly effective in treatments against cancer. The present review addresses certain properties of T. versicolor, as well as its potential applications in different biotechnological fields.

Full textAbstract:
Influence of shiitake mushroom Lentinula edodes on reproduction of Drosophila melanogaster Shiitake mushroom Lentinula edodes is an edible basidiomycete cultivated worldwide, with high nutritious value and diverse biological activity. There has been an increase in its use as food supplement. Influence of shiitake mushroom extract on the reproductive function and development in an object fruit fly Drosophila melanogaster is described in this research. Fruit flies were maintained on banana medium with or without supplementation of shiitake mushroom's extract, standardized per amount of crude polysaccharides. Shiitake extract supplement, 0.030% and 0.015% crude polysaccharides per volume, induced a statistically significant increase in total number of pupae and flies, and promoted pupae viability. Adult drosophilae males, which received shiitake extract supplement for seven days, had a statistically significant reduction in copulation latency, while thirty day exposure to extract promoted a statistically higher rate of mated flies. Females showed an increase in number of mated flies and reduction in copulation latency post seven day feeding period and had no significant effect on mating ability and fertility post thirty days. Further studies are planned to identify the biologically active components of shiitake mushroom hot water extract and to characterize their effects on reproductive function.

Full textAbstract:
Armillaria mellea is a commonly harvested and consumed mushroom in Poland. Several activities of polysaccharides from this species have already been reported. However, polysaccharides from A. mellea growing in the wild in Poland have not yet been investigated. This study was conducted to obtain a crude polysaccharide fraction (AmPS) and investigate its chemical composition and biological properties. Our research suggests that A. mellea is a valuable source of polysaccharides, including β-glucans. 1H NMR and high-performance capillary electrophoresis analysis of AmPS revealed the occurrence of polysaccharides consisted of myo-inositol, mannitol, fucose, galactose, glucose, and mannose. Proteins, uronic acids, and phenolics were present only in trace amounts in the AmPS. The AmPS fraction was found to exhibit strong α-glucosidase inhibitory activity; however, no activity in relation to α-amylase was detected. The fraction was also able to inhibit pro-inflammatory enzymes, i.e., lipoxygenase, cyclooxygenase, and hyaluronidase. Moderate antioxidant and antiradical activity of AmPS was revealed by the ORAC and ABTS assay, respectively. The AmPS fraction was found to have antiproliferative potential against gastric and colorectal cancer cell lines (AGS, HT-29). These findings suggest that AmPS may be considered a health-beneficial food ingredient. Since A. mellea is a commonly known edible mushroom with a long tradition of use, its polysaccharides may be considered safe components for direct consumption or production of nutraceuticals.

Full textAbstract:
Beta-glucans comprise a group of polysaccharides of natural origin found in bacteria, algae, and plants, e.g., cereal seeds, as well as microfungi and macrofungi (mushrooms), which are characterized by diverse structures and functions. They are known for their metabolic and immunomodulatory properties, including anticancer, antibacterial, and antiviral. Recent reports suggest a potential of beta-glucans in the prevention and treatment of COVID-19. In contrast to β-glucans from other sources, β-glucans from mushrooms are characterized by β-1,3-glucans with short β-1,6-side chains. This structure is recognized by receptors located on the surface of immune cells; thus, mushroom β-glucans have specific immunomodulatory properties and gained BRM (biological response modifier) status. Moreover, mushroom beta-glucans also owe their properties to the formation of triple helix conformation, which is one of the key factors influencing the bioactivity of mushroom beta-glucans. This review summarizes the latest findings on biological and health-promoting potential of mushroom beta-glucans for the treatment of civilization and viral diseases, with particular emphasis on COVID-19.

Cosmeceutical formulations containing naturally derived active ingredients are currently preferred by consumers worldwide. Mushrooms are one of the potential sources for cosmeceutical ingredients but relevant research is still lacking. In this study, hot- and cold-water extractions were performed on four locally-cultivated mushrooms—Pleurotus ostreatus, Ganoderma lucidum, Auricularia polytricha and Schizophyllum commune—with the aim to assess the cosmeceutical potential of these mushroom fruitbody extracts. Total phenolics, polysaccharide and glucan content were determined. Antioxidant property of the mushroom extracts was assessed by determining the DPPH radical scavenging, ferric-reducing (FRAP) and superoxide anion (SOA) scavenging activity. Anti-hyaluronidase activity was used as an indicator for the anti-aging and anti-inflammatory property, while anti-tyrosinase activity was evaluated to assess the anti-pigmentation or whitening property of these extracts. Our results showed that total polysaccharide content of P. ostreatus extracts was the highest (235.8–253.6 mg GE/g extract), while extracts from G. lucidum contained the lowest glucan (10.12–10.67%). Cold-water extract from S. commune exhibited substantial tyrosinase inhibition activity (98.15%) and SOA scavenging activity (94.82%). The greatest hyaluronidase activity was exhibited by G. lucidum hot-water extract, with the value of 72.78%. The findings from the correlation analyses suggest that the cosmeceutical properties of these mushrooms can be attributed mainly to the combination of different types of compound such as polysaccharides and phenolics. Overall, cold-water extract of S. commune and hot-water extract of G. lucidum showed the best results and may be further investigated.

Full textAbstract:
Macrofungi production and economic value have been increasing globally. The demand for macrofungi has expanded rapidly owing to their popularity among consumers, pleasant taste, and unique flavors. The presence of high quality proteins, polysaccharides, unsaturated fatty acids, minerals, triterpene sterols, and secondary metabolites makes macrofungi an important commodity. Macrofungi are well known for their ability to protect from or cure various health problems, such as immunodeficiency, cancer, inflammation, hypertension, hyperlipidemia, hypercholesterolemia, and obesity. Many studies have demonstrated their medicinal properties, supported by both in vivo and in vitro experimental studies, as well as clinical trials. Numerous bioactive compounds isolated from mushrooms, such as polysaccharides, proteins, fats, phenolic compounds, and vitamins, possess strong bioactivities. Consequently, they can be considered as an important source of nutraceuticals. Numerous edible mushrooms have been studied for their bioactivities, but only a few species have made it to the market. Many species remain to be explored. The converging trends and popularity of eastern herbal medicines, natural/organic food product preference, gut-healthy products, and positive outlook towards sports nutrition are supporting the growth in the medicinal mushroom market. The consumption of medicinal mushrooms as functional food or dietary supplement is expected to markedly increase in the future. The global medicinal mushroom market size is projected to increase by USD 13.88 billion from 2018 to 2022. The global market values of promising bioactive compounds, such as lentinan and lovastatin, are also expected to rise. With such a market growth, mushroom nutraceuticals hold to be very promising in the years to come.

Full textAbstract:
The aims of the present study were to optimize the operational parameters to maximize the yield of ultrasound-assisted polysaccharide extraction from Volvariella volvacea (straw mushroom) fruiting bodies by using for the first time one-factor-at-a-time and three-level Box-Behnken factorial designs. A maximum polysaccharide yield of 8.28 ± 0.23% was obtained under the optimized conditions of ultrasound power of 175 W, extraction temperature of 57 °C, extraction time of 33 min, and the ratio of liquid to raw material of 25:1, respectively. Compared to the hot-water extraction, the ultrasound-assistance favored the extraction of polysaccharides from V. volvacea for its higher polysaccharide yield and efficiency. Further preliminary polysaccharide structural characterization indicated that ultrasound treatment affected the monosaccharide compositions and ratios, and molecular weight range of polysaccharides extracted from V. volvacea.

Tremella sanguinea is a traditional Chinese medicinal and edible mushroom. Polysaccharides from Tremella mushrooms have received increasing amounts of research attention due to their diverse pharmacological activities. In this study, via the incubation of basidiospores collected from fresh artificially cultivated basidiocarps of T. sanguinea, a haploid yeast strain of T. sanguinea was obtained, and it was found to be a typical loose-slime-forming yeast capable of producing a large amount of exopolysaccharides (EPS). Using DEAE-52 cellulose column chromatography and Sephadex G-100 gel permeation chromatography, the major polysaccharide, named TSPS-1, was separated and purified from the EPS produced by the haploid yeast strain of T. sanguinea. TSPS-1 was a homogeneous polysaccharide with a molecular weight of 2.5 × 103 kDa and consisted of rhamnose, glucose, xylose, mannose and glucuronic acid at a molar ratio of 1: 0.7: 62.2: 24.6: 11.5. The bioactivity of the TSPS-1 polysaccharide was evaluated. The results show that TSPS-1 exhibited noticeable antioxidant activity by scavenging hydroxyl radicals (EC50 = 1.92 mg/mL) and superoxide radicals (EC50 = 1.33 mg/mL), and prebiotic activity by promoting the growth of different probiotic strains in the genus Lactobacillus and Bifidobacterium. These results suggest that the cultivation of the haploid yeast strain can be a promising alternative for the efficient production of valuable T. sanguinea polysaccharides with antioxidant and prebiotic potential.

Recently, much attention has been paid to revealing natural biomaterials for clinical purposes since use of synthetic antioxidants is restricted due to their carcinogenicity. Among various natural antioxidants, polysaccharides, in general, have strong antioxidant activities and can be explored as novel potential antioxidants. The aim of this work was to examine the antioxidant properties of hot water extracted polysaccharides from Ganoderma lucidum in the form of mature fruit bodies, collected from the Bojcinska forest near Belgrade, the Republic of Serbia. Antioxidant properties were assayed in vitro, by the conjugated diene method, reducing power, scavenging abilities against 1.1-diphenyl-2-picrylhydrazyl (DPPH) radicals and chelating ability on ferrous ions. At concentrations of 1 mg/ml, the scavenging ability of G. lucidum polysaccharide extract on DPPH radicals was 74.7 %. At 1 mg/ml, the radical scavenging ability of the positive controls BHT, ascorbic acid and ?-tocopherol were 11.5, 77.1 and 79.4 %, respectively. The antioxidant activity of the polysaccharide extract increased as the concentration increased to 78.0% at 20 mg/ml. Antioxidant activities of ascorbic acid and ?-tocopherol were 63.8 % and 65.4% at 20 mg/ml. Polysaccharide extract from G. lucidum showed steady increase in the reducing activity as concentrations increased to 2.9 at 20 mg/ml. Ascorbic acid, used as a positive control, had a reducing power of 3.9 at 5 mg/ml. Chelating effects of the polysaccharide extract on ferrous ion increased with the increased concentrations. At 0.1-20 mg/ml, the chelating ability of G. lucidum polysaccharide extract was between 10.3-87.8%. The chelating effect of the synthetic metal chelator EDTA was 100% at 0.1-20 mg/ml, while citric acid did not prove to be good chelating agent for ferrous ions in this assay since its chelating ability was 10.3% at 20 mg/ml.

Full textAbstract:
Polysaccharides extracted from fruiting body and mycelia of higher fungi have been found to show various biological activities. Traditionally, these polysaccharides are manufactured by the hot water extraction method. Low polysaccharide yield is the disadvantage of this method. This paper reports the optimal conditions to manufacture polysaccharide with high-yield from Hypsizigus marmoreus mycelia using enzymatic hydrolytic extraction method. Neutral protease was selected as the most cost efficient among six enzymes. The uniform design was further conducted to optimize the enzymatic hydrolytic extraction conditions, and a regression model was constructed to predict polysaccharide yield. The optimized procedures was that 2% (w/w) of neutral protease was added into hydrolytic solution and incubated for 4 h at 43°C, then extracted one time at 100°C for 1 h. Under optimized procedures, the measured polysaccharide yield was 15.73±0.15 (mg/g), which was very close to the predicted value of 16.65 (mg/g). The results validated the accuracy of the regression model and the optimized procedure. When following the optimized procedures, polysaccharide yield was raised 75.0% over that before optimization, and increased by 122.5% and 104.8% over hot-water extraction and microwave assisted extraction methods respectively. This was the first study to apply uniform design for optimizing high yield manufacture of mycelia polysaccharides by enzymatic hydrolytic extraction. We concluded that enzymatic hydrolytic extraction was a simple, high yield method to manufacture polysaccharides from mushroom mycelia and might be used widely in polysaccharide-derived functional foods production.

Mushrooms have bioactive compounds that have antimicrobial, anti-cancer and antioxidant activities among other medicinal benefits. In the present study, we examined the anti-cell proliferation activities of mushrooms from eight genera obtained from the wild in Nigeria. Saccharomyces cerevisiae was used as a model organism to screen mushroom extracts for anti-cell proliferation activity. Polyphenols, high molecular weight polysaccharides and low molecular weight compounds from aqueous extracts were obtained from the test mushrooms using methanol and water respectively. The extracts were screened in vitro at different concentrations of extracts with the CyQuant cell proliferation assay. The high molecular weight polysaccharides from tested mushrooms reduced cell proliferation (96.79% inhibition in Ganoderma multipileum Ding Hou to 66.71% inhibition in Coltricia perennis (L.) Murrill at 10.00mg/ml). Percentage inhibition caused by low molecular weight compounds varied from 94.22% (Ganoderma multipileum) to 76.19% (Coltricia perennis) at 10mg/ml. Percentage of inhibition with the polyphenols varied from 94.12% (Microporus xanthopus Fr) Kuntze) to 79.82% (Coltricia perennis) at high doses. High molecular polysaccharides, low molecular weight compounds and polyphenols from mushrooms have anti-cancer properties. The CyQUANT assay proliferation kit was a very efficient tool for screening extracts from wild mushrooms for anti-cell proliferation activities. Medicinal mushrooms in Nigeria show a lot of promise as a reservoir for drug discovery particularly in the area of cancer research.

Mushroom beta-glucans show immunomodulatory, anticancer and antioxidant features. Numerous papers have been published in the last years on fungal polysaccharides, especially beta-glucans, demonstrating their various biological activities. However substantial data about beta-glucan contents in many mushroom species, especially wild mushrooms, are still missing. Therefore, the main objective of the study was to evaluate β-glucans in 18 species of wild mushrooms and three species of commercial mushrooms for comparison purposes. The contents of β-glucans were determined by the Megazyme method and with the Congo red method, which differ in analytical procedure. Among wild mushrooms, the highest mean β-glucan content assessed with the Megazyme method was found in Tricholoma portentosum (34.97 g/100 g DM), whereas with the Congo red method in Lactarius deliciosus (17.11 g/100 g DM) and Suillus grevillei (16.97 g/100 g DM). The β-glucans in wild mushrooms assessed with the Megazyme method were comparable to commercial mushrooms, whereas β-glucans assessed with the Congo red method were generally higher in wild mushrooms, especially in Russula vinosa, L. deliciosus and S. grevillei. This study indicates wild mushrooms as interesting material for β-glucan extraction for food industry and medicinal purposes.

Full textAbstract:
In this study the antioxidant and neuroprotective activity of an enriched polysaccharide fraction (EPF) obtained from the fruiting body of cultivated P. eryngii was evaluated. Proximate composition (moisture, proteins, fat, carbohydrates and ash) was determined using the AOAC procedures. The EPF was extracted by using, in sequence, hot water and alkaline extractions followed by deproteinization and precipitation with cold ethanol. Total α- and β-glucans were quantified using the Megazyme International Kit. The results showed that this procedure allows a high yield of polysaccharides with a higher content of (1-3; 1-6)-β-D-glucans. The antioxidant activity of EPF was detected from the total reducing power, DPPH, superoxide, hydroxyl and nitric oxide radical scavenging activities. The EPF was found to scavenge DPPH, superoxide, hydroxyl and nitric oxide radicals with a IC50 values of 0.52 ± 0.02, 1.15 ± 0.09, 0.89 ± 0.04 and 2.83 ± 0.16 mg/mL, respectively. As assessed by the MTT assay, the EPF was biocompatible for DI-TNC1 cells in the range of 0.006–1 mg/mL and, at concentrations ranging from 0.05 to 0.2 mg/mL, significantly counteracted H2O2-induced reactive oxygen species production. This study demonstrated that polysaccharides extracted from P. eryngii might be used as functional food to potentiate the antioxidant defenses and to reduce oxidative stress.

The study's goal was to ascertain the chemical composition of various molecules, including uronic acid, protein, and carbohydrate. UV, X-ray Diffraction, and Fourier transform infrared spectroscopy (FTIR). In these assays with lower EC50 values, the study found that HUEP exhibited the strongest antioxidant activity. Various polysaccharide extracts of the mushroom may be used as a readily available food source that is high in natural antioxidants, as a potential food supplement, or even as a medicinal agent, according to the findings of the current study. The results of various in vitro assay systems showed that the polysaccharide ethanolic extract of HUEP has strong antioxidant properties. Extracts from polysaccharides could be useful for creating food additives that are antioxidants.

In this study, we characterized and investigated the pan-genome of three strains of I. obliquus. The genome sizes of JL01, HE, and NBRC8681 were 32.04, 29.04, and 31.78 Mb, respectively. There were 6 543 core gene families and 6 197 accessory gene families among the three strains, with 14 polysaccharide-related core gene families and seven accessory gene families. For terpenoids, there were 13 core gene families and 17 accessory gene families. Pan-genome sequencing of I. obliquus has improved our understanding of biological characteristics related to the biosynthesis of polysaccharides and terpenoids at the molecular level, which in turn will enable us to increase the production of polysaccharides and terpenoids by this mushroom.

Full textAbstract:
The effects of different cooking methods (steaming, boiling, air frying, and oven baking) and cooking times (0, 5, 10, 15, and 20 min) on the bioactive components (total phenol, total flavonoid, crude polysaccharides, and eritadenine), color, texture, microstructure, and volatiles in shiitake mushrooms were investigated in this study. Steaming, boiling, and air frying for 5–20 min could decrease the contents of all the four bioactive components in the shiitake mushroom. However, oven baking for 5 min and 10 min showed the highest contents of total phenolics and total flavonoids, respectively. Moreover, the lowest losses of crude polysaccharides and eritadenine were observed for oven baking for 5 min and 15 min, respectively. The lightness of shiitake mushrooms was decreased by all treatments; however, steaming could keep a higher brightness compared with other methods. The microstructure was damaged by all cooking methods, especially air frying for 20 min. Meanwhile, steaming for 20 min decreased the hardness mostly, and there was no significant difference with air frying for 20 min. All cooking treatments decreased the complexity of the flavors and the relative contents of volatile compounds; the lowest contents were found when boiling for 5 min. From these results it can be seen that the physical, histological, and chemical features in shiitake mushroom were influenced by cooking methods and times. In addition, our results provide valuable information for the cooking and processing of shiitake mushrooms and other fungi.

Agaricus blazei, a mushroom native to Brazil, is a perspective source for food industry. This mushroom has been widely used in folk medicine due to its possible medicinal value. The most important components of fruiting bodies of A. blazei are specific β-glucans with β-(1→3), β-(1→4) andβ-(1→6) glycosidic linkages. These polysaccharides are supposed to be responsible for some healthy properties of mushrooms (anticarcinogenic and antimutagenic ones). β-Glucans are associated with chitin forming water-insoluble chitin-glucan complex. This complex was isolated from fresh and dried mushrooms (separately from caps and stems) by alkali treatment using NaOH solution at 9°C for 2 h. The structure of chitin-glucan complex was analysed by diffuse reflectance FT-IR spectroscopy. β-Glucans were also analysed by Megazyme enzymatic method based on exo-1,3-β-glucanase and β-glucosidase catalysed hydrolysis and photometric determination of the released glucose.

This study was aimed to analyze of polysaccharides from fruiting bodies of Fomitopsis officinalis (Vill.ex.Fr.), Laetipo-rus sulphureus (Bull.ex.Fr.) and Inonotus obliquus (Pers.ex.Fr.) medicinal mushrooms, growing in Mongolia. As a result of “step by step” extraction method we have obtained 4 fractions of polysaccharide (water-soluble: HWE50 and HWE100; cold alkali-soluble CA; hot alkali-soluble HA) form the each mushroom sample. Polysaccharide fraction’s yields extracted by hot water from Fomitopsis officinalis (Vill.ex.Fr.), Laetiporus sulphureus (Bull.ex.Fr.) and Inonotus obliquus (Pers.ex.Fr.) were 3.68%, 8.82% and 12.84%. Yields of alkali-soluble polysaccharides were 18.64%, 68.03% and 28.75%, respectively, which results more than water fractions. The main monosaccharide composition in all polysaccharide fractions were glucose, and a content of glucose was varied 30%-100%. Therefore, they can be considered glucans. Water-soluble polysaccharide fractions contain fucose (until 12%), man-nose (until 18%) and galactose (until 30%). An average molecular mass of water-soluble polysaccharides were calculated Mw 100–150kDa or it can be considered a low, while an average molecular mass of alkali-soluble polysaccharides was a bit high 300–750кDа. All polysaccharides were heterogenic.

Currently, the food and agricultural sectors are concerned about environmental problems caused by raw material waste, and they are looking for strategies to reduce the growing amount of waste disposal. Now, approaches are being explored that could increment and provide value-added products from agricultural waste to contribute to the circular economy and environmental protection. Edible mushrooms have been globally appreciated for their medicinal properties and nutritional value, but during the mushroom production process nearly one-fifth of the mushroom gets wasted. Therefore, improper disposal of mushrooms and untreated residues can cause fungal disease. The residues of edible mushrooms, being rich in sterols, vitamin D2, amino acids, and polysaccharides, among others, makes it underutilized waste. Most of the published literature has primarily focused on the isolation of bioactive components of these edible mushrooms; however, utilization of waste or edible mushrooms themselves, for the production of value-added products, has remained an overlooked area. Waste of edible mushrooms also represents a disposal problem, but they are a rich source of important compounds, owing to their nutritional and functional properties. Researchers have started exploiting edible mushroom by-products/waste for value-added goods with applications in diverse fields. Bioactive compounds obtained from edible mushrooms are being used in media production and skincare formulations. Furthermore, diverse applications from edible mushrooms are also being explored, including the synthesis of biosorbent, biochar, edible films/coating, probiotics, nanoparticles and cosmetic products. The primary intent of this review is to summarize the information related to edible mushrooms and their valorization in developing value-added products with industrial applications.

Mushrooms are rich in biologically active substances. Basidiomycete oyster mushroom or Pleurotus ostreatus is not only widely used in food, but also have radioprotection, preventive effect on recurrent respiratory tract infections, hypocholesterolic action, antitumor effect, strong immunostimulatory activity and other beneficial medical effects. It is considered that β-glucans play significant role in the biological activities of the oyster mushroom. The aim of this research was to study the effect of the addition of various β-glucan containing preparations obtained from the submerged biomass of P. ostreatus on the process of milk fermentation and properties of the finished product. Preparations of β-glucans obtained from submerged cultured P. ostreatus biomass were obtained using different extraction protocols. The content of β-glucans in preparations was determined using Assay Kit (Megazyme). Preparations were added to milk in different concentrations before the introduction of starter culture. A starter containing Lactobacillus acidophilus n.v. Er 317/402 strain «Narine» was used for fermentation. The titratable acidity was controlled during the fermentation. Physicochemical, structural-mechanical properties (water holding capacity) of the obtained samples were studied. The sensory evaluation of the products was evaluated. Results show that the addition of preparations increase the glycolytic activity. Structural-mechanical properties of yogurt samples fortified by β-glucan-containing preparations depend on the preparation and its concentration. Sensory evaluation showed that experimental samples differed not only from the control sample but also from each other.

Mushrooms have been widely used in traditional medicine for the treatment of various diseases. Today, their therapeutic value is scientifically studied and appreciated. Research indicates that polypores - a large group of fungi of the phylum Basdiomycota - exhibit antiviral, antimicrobial, anticancer, anti-allergic, anti-atherogenic, hypoglycemic, hepatoprotective and anti-inflammatory activities. Phellinus igniarius, a polypore mushroom, is one of the most used in traditional Asian medicine. Its potent anticancer activity has been repeatedly reported. In the past two decades, numerous pharmacologically active metabolites have been isolated and identified from P. igniarius. Among the large number of compounds, the most active group are polysaccharides. They modulate immune responses and inhibit tumor growth.

The chemical and nutritional constituents of mushrooms can alter significantly when grown on different substrates. Based on this fact, an approach was made to cultivate a new type of mushroom, Hengshan Astragalus Shiitake, by growing Shiitake mushrooms on beds supplemented with the roots of an edible herbal plant, Astragalus membranaceus. In this study, three green extraction techniques, including microwave-enzyme assisted (MEA), ultrasound-enzyme assisted (UEA) and microwave-ultrasound-enzyme assisted (MUEA) extractions, were used to compare both the yield and antiproliferative activity of the polysaccharide-rich extracts (PREs) from HAS in human colorectal carcinoma cells (HCT 116). Both HAS-A and HAS-B extracts contain significantly higher amounts of polysaccharides when compared to the control (Shiitake extract), regardless of the extraction methods. The PREs from HAS-B have significantly higher anti-proliferative activity in HCT 116 compared to the control when using the UEA extraction method. Our findings demonstrate that HAS-B can become a novel functional food with anti-proliferative activities and the optimization of UEA extraction would help to develop new active extract-based health products.

When added to mushroom growing substrates, edible and medicinal herbs affect the mushrooms’ nutritional and medicinal value. In this study, polysaccharides (P0OP-I and P15OP-I) were extracted and purified from oyster mushrooms grown on substrates supplemented with 0% and 15% Astragalus roots (P0 and P15), respectively, and their chemical structure and immunobiological activities were compared. P15OP-I and P0OP-I were extracted using ultrasound-assisted hot water and deproteinized with the Sevage method, depigmented with 30% H2O2, desalted with dialysis, and purified using DEAE-52 cellulose and Sephadex G-100 dextran column chromatography. The molecular weight of P0OP-I and P15OP-I was 21,706.96 and 20,172.65 Da, respectively. Both were composed of monosaccharides D-mannose, galacturonic acid, D-glucose, D-galactose, and L-arabinose but in different molar ratios, and both were connected by a pyranoside linkage. P15OP-I consisted of higher contents of mannose, glucose, galactose and arabinose and lower content of galacturonic acid as compared to P0OP-I. Both P0OP-I and P15OP-I induced NO and TNF-α production but did not show cytotoxic effect or induce ROS generation in RAW264.7 cells. P15OP-I showed a stronger ability to promote NO and TNF-α production relative to P0OP-I. In vitro experiments showed that the immunomodulatory activity of P0OP-I and P15OP-I in RAW264.7 macrophages were mediated by the JNK/MAPK, Erk/MAPK, and NF-κB signaling pathways. The results would be helpful for elucidation of the health promoting mechanism of Astragalus oyster mushrooms as a source of neutraceuticals.
