Abstract:
Bioethanol production from sugar fermentation is one of the most sustainable alternatives to substitute fossil fuel. production of bioethanol from low grade dates which are rich of sugars. An available sugar from a second grade dates (reduction sugar) was 90g/l in this study. Sugar can be served as essential carbon sources for yeast growth in aerobic condition and can also be converted to bioethanol in anaerobic condition. The effect of various parameters on bioethanol production, fermentation time, pH-values, inoculum size and initial sugar concentration were varied in order to determine the optimal of bioethanol production. The highest bioethanol yield was 33g/l which was obtained with sugar concentration 90 g/l, inoculum size 1%, 52h time and pH-value 5.

Abstract:
Abstract Molasses, a by-product of the sugar manufacturing process, generally comprises approximately 50% (w/w) of total sugars, but it is currently used primarily [1] as an animal feed and as a raw material in alcohol production. Currently, the sugar production is more than 160 million tones worldwide. Its byproduct molasses contain heavy metals which have growthinhibitory effect. The main sugar content in molasses is sucrose which often need to be hydrolyzed to glucose and fructose especially for utilization by Lactobacillus species. Lactobacillus species can convert sugar content to lactic acid with great efficiency, which is a valuable chemical. Lactic acid production from sugar molasses using batch fermentations with Lactobacillus casei and Lactobacillus sp. MKT878 were investigated in this study. Results showed, that both examined Lactobacillus species could grow on molasses despite the heavy metals inhibitory effects. The conversion of sugar content to lactic acid was successful with yield between 55-80 g/g.

Abstract:
Separate hydrolysis and fermentation (SHF) were employed to produce bio-ethanol from the jatropha stem and husk. This study investigates the favorable condition required to improve yield of monomeric sugars. Substrate was pretreated physically at first through cutter mill and subsequently by ball milling. Acremonium cellulase and optimash BG hydrolyzed the pretreated sample into fermentable sugars. In condition of 10% substrate concentration, ball milling for 60 min and 4 FPU/g enzyme loading and optimum sugar yield were observed. By comparison, jatropha stem is more favorable feedstock compared to jatropha husk in terms of both inherent sugar composition and sugar yield in enzymatic saccharification (hydrolysis). Yeast Saccharomyces cerevisiae, capable of converting hexose sugars into ethanol,was utilized in fermentation step. It was possible to extract 0.14 L and 0.20 L of ethanol per kg of dry substrate-based jatropha husk and jatropha stem, respectively. Bangladesh J. Sci. Ind. Res.54(1), 39-46, 2019

Abstract:
AbstractA group of cassava landraces that occur naturally in Amazonia (Manihot esculenta Crantz) are known as mandiocaba or sugary cassava because they have high free sugar content, making them a possible feedstock for the production of syrup. The objective of the study was to evaluate the technological viability of obtaining sugary cassava syrup and to characterize the physical and physicochemical properties of the product. The yield of the syrup (80 °Brix) obtained from the manipueira (liquid obtained by crushing and filtering the cassava) concentration was 262.72 g per plant. The reducing sugars represented 77.26% of total sugars, the density was 1.4210 g cm–3 at 20°C, and the volumetric expansion coefficient was 38.6 m K–1. The Newtonian behavior and activation energy (≥69.65 kJ gmol–1) were similar to that of honey found in the literature.

Abstract:
ABSTRACT Lactococcus lactis produced more exopolysaccharide (EPS) on glucose than on fructose as the sugar substrate, although the transcription level of the eps gene cluster was independent of the sugar source. A major difference between cells grown on the two substrates was the capacity to produce sugar nucleotides, the EPS precursors. However, the activities of the enzymes required for the synthesis of nucleotide sugars were not changed upon growth on different sugars. The activity of fructosebisphosphatase (FBPase) was by far the lowest of the enzymes involved in precursor formation under all conditions. FBPase catalyzes the conversion of fructose-1,6-diphosphate into fructose-6-phosphate, which is an essential step in the biosynthesis of sugar nucleotides from fructose but not from glucose. By overexpression of the fbp gene, which resulted in increased EPS synthesis on fructose, it was proven that the low activity of FBPase is indeed limiting not only for EPS production but also for growth on fructose as a sugar source.

Abstract:
Sugar cane limitation was found in refined sugar production, so it needed other alternative in sugar production with various cassava. Taro, sweet potato and cassava as high carbohydtrate of various cassava can be used in liquid sugar production by using microbial enzyme. Amiloglucosidase Mucorjavanicus can degrade various cassava carbohydrate. To know liquid sugar quality of various cassava, the use of amyloglucosidase Mucorjavanius in liquid sugar production with various cassava were researched. Observation were conducted with six treatments of amyloglucosidase concentration, that is 0.00 percent (control); 0.05 percent; 0.10 percent; 0.15 percent; 0.20 percent and 0.25 percent. the liquid sugar quality was detected by measuring reduction sugar (DNS method), water content (AOAC), pH, colour, and amyloglucosidase activity (Samogeny titration method). Statistical analysis used Complete Randomized Design. The result showed that the highest reduction sugar and amyloglucosidase activity on each sugar were found on liquid sugar 0.20 percent enzyme (p less than 0.05). the highest reduction sugar and amyloglucosidase activity, was respectively on Taro 323 mg/100ml and 54.91 unit/100 ml; sweet potato 242 mg/100 ml and 47.72 unit/100 ml; and cassava 188 mg/100 ml and 41.09 unit/100 ml. the lowest total solid or the highest water content between three sugars was on taro liquid sugar 0.20 percent enzyme, that is 64.97 percent and 35.03 percent respectively (p less than 0.05). pH liquid sugar onthree various cassava was on range between 5.78-6.01. the best colour was on taro liquid sugar, that is brown to yellow. From three sugars with different raw material, the best sugar quality was tari liquid sugar with 0.20 percent.

Abstract:
Date palm fruits (Phoenix dactylifera) contain high levels of fructose and glucose sugars. These natural sugar forms are healthy, nutritional and easily assimilate into human metabolism. The successful production of soluble date sugar powder from nutritious date fruits would result in a new food product that could replace the commercial refined sugar. In this work, a novel process technology based on the supercritical extraction of sugar components from date pulp was modeled and simulated using Aspen Plus software. The process model consisted of three main steps that were individually simulated for their optimal working conditions as follows: (a) freeze-drying of the date pulp at −42 °C and 0.0001 bar; (b) supercritical extraction of the sugar components using a 6.77 wt.% water mixed CO2 solvent system at a pressure of 308 bar, temperature of 65 °C, and CO2 flow rate of 31,000 kg/h; and (c) spray-drying of the extract using 40 wt.% Gum Arabic as the carrier agent and air as drying medium at 150 °C. The overall production yield of the process showed an extraction efficiency of 99.1% for the recovery of total reducing sugars from the date fruit. The solubility of the as-produced date sugar powder was improved by the process selectivity, elimination of insoluble fiber contents, and the addition of Gum Arabic. The solubility of the final date sugar product was estimated as 0.89 g/g water.

Abstract:
The need to intensify the process of extracting sugar substances from sweet sorghum stalks in order to improve the quality and yield of the target product has been substantiated. Existing techniques of sugar substance extraction used in sweet sorghum processing technologies have been analyzed. The application of a combined technique for extracting sugary substances has been proposed implying the production of pressed and diffusion juice. The results of optimizing the press technique of juice extraction from sorghum stalks are given. The equations of material balance of products and sugars have been built, depending on such factors as the degree of pressing, the initial content of solids and sugars in the stalks. A procedure for calculating the yield of pressed juice, cake, and the content of total sugars has been devised, according to which the preliminary pressing of the stalks ensures the extraction of juice in the range of 25‒35 %, the yield of the pressed cake is 75‒65 % on average, with a sugar content exceeding 60 %. It has been experimentally established that the use of the anti-current process of extraction of sugar substances from the pressed cake ensures their complete extraction from raw materials. The rational parameters for this process have been defined. At a temperature of 66–70 °C and a duration of 20 minutes, it is possible to obtain an extract whose content of solids is 13.0 %, total sugars ‒ 11.10 %, and whose purity is 85.38 %. The research was carried out in order to intensify the extraction of sugar substances from sweet sorghum plant raw materials, to improve the technical level of the extraction process, and implement the devised method under industrial conditions. Further implementation of these results in the food industry could make it possible to establish the production of a wide range of sugar-containing products, both organically and as a natural substitute for sugar in food products.

Abstract:
Aim: This study investigated the production of lipids and carotenoids and associated growth properties by the oleaginous red yeast Rhodosporodium toruloides strain ATCC 204091, using C5 and C6 sugar streams of lignocellulosic waste hydrolysate separately and in combination (C5+C6). Methodology: Cell density, wet and dry biomass weight, concentration of total sugars and reducing sugars were determined at various time intervals during cell growth in media containing C5, C6 and mixed sugars. Lipid and carotenoids were extracted and the media were compared with respect to production. Results: Production of lipid (22.25%) and carotenoids (19 mg l-1) was highest in C6 sugar, as compared to mixed sugars and C5 sugar. Interpretation: Due to the versatility of Rhodosporodium toruloides strain ATCC 204091 for utilizing C6 and C5 sugars present in waste hydrolysates, it has been projected as a good choice for cultivation in “waste” hydrolysates.

Abstract:
Overproduction of sugar causes a reduction in the acreage under sugar beet. That is why new non-food technologies for exploitation of agricultural products are sought. Utilization of beet for liquid fuel production could be one of them. The aim of experiments with sugar beet raw juice fermentation was to verify the possibility to return a part of distiller’s slops back to the fermentation process and thereby to obtain stillage with higher content of dry solids. This would bring about energy savings during slops thickening and drying. Tests with recycling of different portions of stillage (20, 25 and 30%) back to the fermentation stage were carried out. No significant increase in dry solids content in mash was found and therefore no energy savings during thickening can be expected. The only savings can be made in water consumption that is replaced by slops.

Full text
Abstract:
Three switchgrass cultivars (‘Performer’, ‘BoMaster’, and ‘Colony’ switchgrass) were delignified using NaOH at varying concentrations and residence times at 121 oC for improved sugar production in enzymatic hydrolysis. Because of its greater carbohydrate/lignin ratio and the more substantial lignin reduction upon alkaline attack, ‘Performer’ switchgrass gave greater sugar productions under all the pretreatment conditions investigated. Maximum sugar production from ‘Performer’ was 425 mg/g raw biomass, which was achieved at 1% NaOH and 0.5 h. Sugar production increased with the improvement of delignification until the lignin reduction reached 30%. The more severe pretreatment conditions, which led to greater lignin reductions, did not favor the increase of sugar production because of greater solid losses. Linear models were proven effective in correlating a modified severity parameter log(Mo) to lignin reduction and sugar production of ‘Performer’ switchgrass.

Abstract:
To expand the range of soluble carbon sources for enzyme production by the microbial system, we investigated the ability of different sugars in cellulase production. Carbon sources play a vital role in cell metabolism and the synthesis of cellulase. Although the insoluble cellulosic materials are considered the most effective natural inducers for cellulase production by microorganisms in terms of both enzyme yield and productivity, their insolubility causes many problems and presents a major drawback that is partly responsible for the high cost of cellulase production. Mostly, the insolubility of sugar polymer leads to difficult and complex fermentation operations, including sterilization, cell biomass measurement, mixing and aeration of the fermentation broth, continuous feeding/sampling, and subsequent enzyme purification. Second, cellulase gets absorbed into the solid cellulose surface, leading to enzyme loss. The present paper gives a comparative view on the utility of pure sugars (lactose, CMC, sucrose, maltose, cellobiose, xylose, trehalose, arabinose) and sugar alcohols (sorbitol, mannitol) on cellulase production by various fungal strains. It also describes the blending effect of sugars as well as sugar alcohols on cellulase production by fungal strains.

Abstract:
Oba, M. 2011. Review: Effects of feeding sugars on productivity of lactating dairy cows. Can. J. Anim. Sci. 91: 37–46. Sugars are water-soluble carbohydrates that are readily available in the rumen. Although sugars ferment faster than starch or fibre in the rumen, the rates of disaccharide hydrolysis and monosaccharide fermentation vary greatly depending on the type of sugar and rumen environment. Despite rapid fermentation in the rumen and their potential to provide greater fermentable energy to enhance microbial protein production, feeding sugars in place of dietary starch sources may not decrease rumen pH or improve N utilization efficiency and milk protein production in dairy cows. However, feeding high-sugar diets often increases dry matter intake, butyrate concentration in the rumen, and milk fat yield. These nutritional characteristics of sugars may allow us to use high-sugar feedstuffs as an alternative energy source for lactating dairy cows to increase dietary energy density with reduced risk of rumen acidosis, but there is little evidence in the literature to indicate that the synchrony of rumen fermentation would be enhanced by feeding high-sugar diets with high soluble protein. Greater butyrate production from feeding high-sugar diets is expected to enhance proliferation of gut tissues, but its physiological mechanisms and effects of butyrate metabolism on overall productivity of dairy cows warrant further investigations.

Abstract:
Sugar is an important source of energy for the human body although it receives blame for many health problems, without it, the body would cease to function properly. Nearby thirty percent of the world sugar comes from sugar beet. Production of sugar beet globally spans diverse regions with a wide range of climatic and agro-ecological regions which shows exclusive management challenges. Fertilizer or nutrient management is one of the practices that associate with fertilizer use efficiency and production of the crops including sugar beet. As the nutrient management interacts with different agro-ecological areas and soils, the fertilizer recommendations and management have become regional and site-specific. Maximizing beet and sugar yields, the knowledge of the management of the fertilizers or nutrition is very essential. This article is to understand the impact of different fertilizers in different management practices including the major nutrients of the crop, fertilizer rate, timing, and method of application either solely or in a mixture or integrated manner with reviewing diverse research experiments. Moreover, it will help to approach future strategies and needs for making the production of sugar beet as a cost-effective crop with new improving management technologies for the farmers.

Abstract:
Liquid sugar is a sweetener that is widely used in the food industry. Apart from starch, liquid sugar can be produced from cellulose hydrolysis by using cellulase enzymes. This study aims to obtain the best concentration of cellulase enzymes in the production of cellulose liquid sugar in the skin of red dragon fruit. The production of liquid sugar uses the method of hydrolysing enzymes of different concentrations (1%,2%,3%). The results showed that there was no significant influence on the characteristics of liquid sugars resulting from the addition of three different enzyme concentrations. The observed characteristics are total sugar content, water, ash content, viscosity and color. Enzyme concentration of 3% is the best liquid sugar based on observations of total sugar content and color.

Climatic changes are the main concerns of varying crop yields nowadays. The world has reached where it will start a journey towards deterioration. Sustainable production will ensure food security in days to come. Sugarcane is considered a major crop for sugar as well as bio-fuel production in the world. Environmental changes have severely affected the cane production worldwide especially in the developing countries because of relatively low adaptive capacity, high vulnerability to natural hazards, poor forecasting systems and mitigating strategies. The changing rainfall patterns (Monsoon season) during July to September due to climate change may result in water stress induced by drought although harvesting efficiency is expected to increase. These studies also expound on the mitigation and adaptation strategies that can be employed in the sugarcane industry as a way of reducing losses in sugarcane production. This will also help to know how cane production is affected due to extreme environmental changes in Pakistan.

Abstract:
The small sugar industry can afford to idle along using Research and development (R & D) produced (and paid for) by other sugar industries but when it is big with world standards it's a different matter. This study was important because Pakistan is 5th largest producer of sugarcane but it still lacks major advancement in production and marketing. The largest producers are Brazil, India, Thailand, China, and Pakistan accounting for more than 70% of world production. Brazil has the highest area (5.34 million hectares) while Australia has the highest productivity a n d s u g a r c a n e y i e l d (85 tons per hectare). Sugarcane is the second largest cash crop of Pakistan and is being cultivated on 1.06 million hectares with 55 t ha cane yield and sugar yield of 5.5 t ha, contributing around 3.6 % of Gross domestic production. The installed capacity of 85 sugar factories is to produce 7.5 million tons of refined sugar and domestic demand is around 4.5 million tons. This shows it’s export potential of 3.5 million tons, annually.

Abstract:
Dietary sugars are linked to the development of non-alcoholic fatty liver disease (NAFLD) and dyslipidaemia, but it is unknown if NAFLD itself influences the effects of sugars on plasma lipoproteins. To study this further, men with NAFLD (n = 11) and low liver fat ‘controls’ (n = 14) were fed two iso-energetic diets, high or low in sugars (26% or 6% total energy) for 12 weeks, in a randomised, cross-over design. Fasting plasma lipid and lipoprotein kinetics were measured after each diet by stable isotope trace-labelling. There were significant differences in the production and catabolic rates of VLDL subclasses between men with NAFLD and controls, in response to the high and low sugar diets. Men with NAFLD had higher plasma concentrations of VLDL1-triacylglycerol (TAG) after the high (P<0.02) and low sugar (P<0.0002) diets, a lower VLDL1-TAG fractional catabolic rate after the high sugar diet (P<0.01), and a higher VLDL1-TAG production rate after the low sugar diet (P<0.01), relative to controls. An effect of the high sugar diet, was to channel hepatic TAG into a higher production of VLDL1-TAG (P<0.02) in the controls, but in contrast, a higher production of VLDL2-TAG (P<0.05) in NAFLD. These dietary effects on VLDL subclass kinetics could be explained, in part, by differences in the contribution of fatty acids from intra-hepatic stores, and de novo lipogenesis. The present study provides new evidence that liver fat accumulation leads to a differential partitioning of hepatic TAG into large and small VLDL subclasses, in response to high and low intakes of sugars.

Abstract:
Coloring substances (colorants) adsorbing on the surface of growing sugar crystals or incorporating into the crystal lattice, reduce the speed of sucrose crystallization, increase the color and hygroscopicity of sugar, tend to clod during storage. Most of the colored nonsugars are found on the surface of yellow sugar crystals so it is possible to reduce the color of yellow sugar by 50-80% with the help of affinity. The distribution of coloring substances in the crystals of yellow sugar and their composition have not been studied sufficiently. The purpose of this research was to study the coloring substances of yellow sugar obtained during the sugar beet processing. As a result of the research it was found that up to 90% of yellow sugar coloring substances is in the film located on the crystals surface and can be easily removed by affinity. It was experimentally learnt that the main products in the coloring matter are the products of alkaline decomposition of reducing substances: their content is 10 times higher than that of caramel and melanoidins, which is in good agreement with the conditions for carrying out the technological processes of sugar beet production. The content of all groups of coloring substances correlates well with the crystals size: the least fraction of the colorants contains a fraction of 0.5 mm in size; in crystals of a larger and smaller size, the content of all groups of coloring substances increases. Yellow sugar coloring substances are extracted with acetic acid most effectively, because it is a weakly polar proton solvent. The noted absorption maxima for aqueous, acetate and ethyl acetate extracts do not coincide, which indicates the presence of various coloring agents in them..

Abstract:
Water kefir is a fermented probiotic beverage produced by fermentation of dried sugary fruits and sugar using water kefir grains. Sucrose is used as a sugar source in the traditional production of water kefir. The aim of this study is to determine the effects of grape molasses, honey and unrefined sugar on water kefir grains instead of sucrose. In the study, 4 groups were formed: grape molasses (10 g), honey (10 g), unrefined sugar (10 g) and refined sugar (10 g). 2 g of water kefir grain and 500 mL of drinking water were used for each group. And each group samples were fermented for 25°C 48 hours. The study continued for 5 weeks. The pH values and the titratable acidity values of water kefir samples and the weight of water kefir grains were determinated once every two day, while microbiological analyzes (Lactobacillus spp., Lactococcus spp. and yeast contents) and ethanol content of samples were determinate once every 15 days. In this study; it has been observed that the use of different sugars has no significant effect on the weights of the water kefir grains. In addition, it was determined that the Lactococcus spp. and yeast amounts in the water kefirs were higher in the samples produced by using honey and grape molasses. As a result, it was revealed that grape molasses, honey and unrefined sugar could be used as fermentation substrate in production of water kefir. At the same time, water kefir can be shown as an alternative fermented product for vegan consumers with allergies to dairy products.

Abstract:
Sugar beet pulp, a byproduct of sugar beet processing, can be used as a feedstock in second-generation ethanol production. The objective of this study was to investigate the effects of pretreatment, of the dosage of cellulase and hemicellulase enzyme preparations used, and of aeration on the release of fermentable sugars and ethanol yield during simultaneous saccharification and fermentation (SSF) of sugar beet pulp-based worts. Pressure-thermal pretreatment was applied to sugar beet pulp suspended in 2% w/w sulphuric acid solution at a ratio providing 12% dry matter. Enzymatic hydrolysis was conducted using Viscozyme and Ultraflo Max (Novozymes) enzyme preparations (0.015–0.02 mL/g dry matter). Two yeast strains were used for fermentation: Ethanol Red (S. cerevisiae) (1 g/L) andPichia stipitis(0.5 g/L), applied sequentially. The results show that efficient simultaneous saccharification and fermentation of sugar beet pulp was achieved. A 6 h interval for enzymatic activation between the application of enzyme preparations and inoculation with Ethanol Red further improved the fermentation performance, with the highest ethanol concentration reaching26.9±1.2 g/L and86.5±2.1%fermentation efficiency relative to the theoretical yield.

Abstract:
The competitive reactions of lignocellulose hydrolysis and monosaccharide degradation in the subcritical water (SCW) hydrolysis of coconut husk were investigated to optimize the reducing sugar yield. Optimization analysis was performed by response surface methodology (RSM) and kinetics studies. Parameters of process optimization were varied at 130-170 °C for 15-45 min. The reducing sugars were measured using the Dinitro salicylic acid method. The sugar yield increased when the temperature increased from 130 °C to 170 °C. The highest reduction sugar yield of 4.946 g/L was obtained at 183.6 °C for 4.8 min and 23.4 liquid/solid ratio (LSR). Kinetics studies were carried out at temperature variations of 150, 170, and 190 °C and pressures of 60, 80, and 100 bar for 5 to 60 min. The yield of reducing sugar decreased with increasing temperature. The kinetic model 2B is the best method to explain the competitive reaction kinetics of coconut husk hydrolysis. This research is an innovation to increase the reducing sugar to make the process more commercially viable. Copyright © 2022 by Authors, Published by BCREC Group.

Abstract:
Abstract As one way to eliminate the issues found in the preceding generation, feedstock exploration in second-generation bioethanol production remains an issue, especially for a tropical country such as Indonesia. From exotic fruit by-products, durian holds a promising perspective that rests on its abundance, superb carbohydrate content and limited usage until now. This work presents the first-ever utilization of durian seeds for sugar production under optimized conditions through alkaline hydrolysis. A simple form of sugar was extracted by varying four parameters, namely substrate loading, NaOH concentration, hydrolysis time and hydrolysis temperature. Response surface methodology based on the Box-Behnken design was employed to outline the most optimum parameter values. Analysis of variance revealed that the quadratic model fit the data appropriately with the order of significance as substrate loading &gt; hydrolysis time &gt; NaOH concentration &gt; hydrolysis temperature. The optimized conditions for reducing sugar yield, as high as 2.140 g/L, corresponded to &lt;50 g/L substrate loading, 0.522 M NaOH, 60 minutes of hydrolysis time and 80oC hydrolysis temperature. The possible ethanol content of 1.094 g/L was also expected under optimized conditions, demonstrating great potential in second-generation bioethanol production. Second-generation bioethanol production from a non-edible feedstock (durian seeds) is optimized by varying key parameters in the alkaline hydrolysis process, showing high yields of fermentable sugars.

Abstract:
Lactic acid is a high-value molecule with a vast number of applications. Its production in the biorefineries model is a possibility for this sector to aggregate value to its production chain. Thus, this investigation presents a biorefinery model based on the traditional sugar beet industry proposing an approach to produce lactic acid from a waste stream. Sugar beet is used to produce sugar and ethanol, and the remaining pulp is sent to animal feed. Using Bacillus coagulans in a continuous fermentation, 2781.01 g of lactic acid was produced from 3916.91 g of sugars from hydrolyzed sugar beet pulp, with a maximum productivity of 18.06 g L−1h−1. Without interfering in the sugar production, ethanol, or lactic acid, it is also possible to produce pectin and phenolic compounds in the biorefinery. The lactic acid produced was purified by a bipolar membrane electrodialysis and the recovery reached 788.80 g/L with 98% w/w purity.

Abstract:
Previous studies have analyzed mainly the spatial distribution of grapes quality parameters at the plot scale, and concluded that grapes sugar content is a variable parameter, with a less predictable spatio-temporal evolution. Our study aimed to identify a pattern of spatial variation of grapes sugar content at a regional scale, under the temperate continental climate of the Huşi (Romania) wine growing region. In order to do this, grapes sugar content was analyzed in relation to climate. The conditioning of grapes sugar content by climatic factors was analyzed based on regression models (Pearson correlation coefficient, coefficient of determination, linear regression). Spatial variation of grapes sugars content was achieved by the regression – kriging approach, using climate suitability as predictor. Spatial variation of obtainable wine types was achieved by classifying the spatial distribution of grapes sugar content, according to DOC wine production regulation for the Husi area. The study revealed that among climatic factors, the actual sunshine duration is the most influential one on grapes sugar content. Mapping grapes sugar content generated a coherent spatial distribution pattern at the vineyard scale, as it significantly correlates with terrain altitude. Based on grapes sugar content spatial variation, two areas with different potential for sugars accumulation into grapes were delineated. The outcomes reveal that grapes sugar content presents significant correlations with climate variables specific to vineyards and with climate suitability for wine production. Knowing these correlations allows revealing patterns that determine the spatial distribution of the grapes sugar content.

Abstract:
Residual streams from lignocellulosic processes contain sugar mixtures of glucose, xylose, and mannose. Here, the industrial workhorse Corynebacterium glutamicum was explored as a research platform for the rational utilization of a multiple sugar substrate. The endogenous manA gene was overexpressed to enhance mannose utilization. The overexpression of the xylA gene from Xanthomonas campestris in combination with the endogenous xylB gene enabled xylose consumption by C. glutamicum. Furthermore, riboflavin production was triggered by overexpressing the sigH gene from C. glutamicum. The resulting strains were studied during batch fermentations in flasks and 2 L lab-scale bioreactors separately using glucose, mannose, xylose, and a mixture of these three sugars as a carbon source. The production of riboflavin and consumption of sugars were improved during fed-batch fermentation thanks to a dynamic inoculation strategy of manA overexpressing strain and xylAB overexpressing strain. The final riboflavin titer, yield, and volumetric productivity from the sugar mixture were 27 mg L−1, 0.52 mg g−1, and 0.25 mg L−1 h−1, respectively. It reached a 56% higher volumetric productivity with 45% less by-product formation compared with an equivalent process inoculated with a single strain overexpressing the genes xylAB and manA combined. The results indicate the advantages of dynamic multi strains processes for the conversion of sugar mixtures.

Abstract:
Wine industry generates large volumes of wastewaters resulting from numerous cleaning operations that occur during the different stages of winemaking. Disposal of these effluents in the environment causes huge problems due to their high organic and inorganic load and seasonal variability. The bioconversion of winery wastewaters in valuable product, such as xanthan, is an important alternative to overcome environmental problems. In this research, the possibility of xanthan production using Xanthomonas campestris on blended wastewaters from different stages of white and rose wine production with initial sugar content of 50 g/L was investigated. In addition to the media parameters (content of sugars, total and assimilable nitrogen, phosphorus, total dissolved salts and apparent viscosity), raw xanthan yield and degree of sugar conversion into product were determined in order to examine the success of xanthan biosynthesis. In applied experimental conditions, xanthan yield of 20.92 and 30.64 g/L and sugar conversion into product of 40.23 and 60.73% were achieved on wastewaters from white and rose wine production, respectively. The results of these experiments suggest that winery wastewaters, after additional optimization of the process in terms of the substrate composition and the cultivation conditions, may be a suitable raw material for industrial xanthan production.

Abstract:
Bioethanol produced from renewable biomass, such as sugar, starch, or lignocellulosic materials, is one of the alternative energy resources, which is both renewable and environmentally friendly. Although, the priority in global future ethanol production is put on lignocellulosic processing, which is considered as one of the most promising second-generation biofuel technologies, the utilization of lignocellulosic material for fuel ethanol is still under improvement. Sugar-based (molasses, sugar cane, sugar beet) and starch-based (corn, wheat, triticale, potato, rice, etc.) feedstock are still currently predominant at the industrial level and they are, so far, economically favorable compared to lingocelluloses. Currently, approx. 80 % of total world ethanol production is obtained from the fermentation of simple sugars by yeast. In Serbia, one of the most suitable and available agricultural raw material for the industrial ethanol production are cereals such as corn, wheat and triticale. In addition, surpluses of this feedstock are being produced in our country constantly. In this paper, a brief review of the state of the art in bioethanol production and biomass availability is given, pointing out the progress possibilities on starch-based production. The progress possibilities are discussed in the domain of feedstock choice and pretreatment, optimization of fermentation, process integration and utilization of the process byproducts.

Abstract:
Sugar production is one of the most complex and energy-intensive. Conditions of high competition of modern reality bring to the fore such indicators as quality, energy consumption, cost. Such conditions dictate the need to apply the latest scientific advances in the automation of sugar production technologies. The automation of the sugar industry ensures high-quality, efficient operation of all technological sections of the sugar plant only through a comprehensive approach to solving this problem. One of the main problems in creating the ACS TP of the sugar industry is the stabilization of the flow line of the main product of sugar technology, as well as maintaining optimal levels of product stock in intermediate (buffer) collections of sugar technology. The technological complex of the sugar industry enterprise consists of areas of procurement, storage, preparation of raw materials for processing, departments of juice production, purification of diffusion juice, areas of finished product production, storage and auxiliary production. Increasing productivity in sugar factories, developing new technology to improve quality, increase the efficiency of sugar industries that require renewal, as well as improving management systems using modern measuring and automation tools. Automation of technological processes with the use of automated complexes, machines, mechanisms, modern means of automation and computer technology is one of the main directions of scientific and technological progress in all sectors of the economy. The analysis and development of the automated system of dispatch control of the drying process of pulp in sugar production is carried out in the work. The system is based on SCADA - Trace Mode 5.10 system manufactured by AdAstra. The result is a fully functional system that can be used in sugar production and the advantage of its implementation is to increase efficiency compared to existing systems.

Abstract Hazelnut shells are generated in large amounts from hazelnut processing. Currently, it is used as fuel. However, reuse in bioprocessing can release remarkable content of sugars, which can be used for production of additives such as enzymes widely used in the food industry. Thus, the present study was undertaken to determine the effect of single and combined chemical and enzymatic hydrolysis on the production of fermentable sugars from hazelnut shells. Batch hydrolysis was carried out under various conditions to select optimal conditions. The results revealed that an optimal sugar concentration of about 19.2 g/l was achieved after 3.42% (w/w) dilute acid pretreatment conducted at 130°C for 31.7 min and enzymatic load of 200 U/g for 24 h. The overall sugar yield was calculated as 72.4% (g reducing sugar/g total carbohydrate). Therefore, hazelnut shells can be considered a suitable feedstock to compete with synthetic sugars used in fermentations.

Abstract:
Due to environmental concerns and the rising prices of petroleum products, usually bio-ethanol is being produced in greater amount from sugar cane molasses in Pakistan. In this work various properties related to molasses are being analyzed by performing experiments at the Distillery Plant, AASML (AlAbbas Sugar Mills Limited), Mirpurkhas, Sindh, Pakistan. Brix, Sucrose, pH, ethyl alcohol, RS (Reducing Sugar), TSI (Total Sugar as an Invert), TS (Total Sugar), purity and presence of micro-organisms are scrutinized. In addition, the effects of quality parameters of pre-fermentation and fermentation for ethyl alcohol production, time impact on stored molasses and consequences of rain on quality of molasses are studied. It was observed from the study that good quality molasses which is the raw material for alcohol production should be used in fermentation process. Molasses must be stored in steel tanks to prevent it from contamination and loss of fermentable sugars. The prefermenters need to steam sterilized, cleaned and washed before inoculation of yeast cells so that the yeast grows healthy to produce maximum ethyl alcohol in fermenters. The water used for hydrolysis of molasses in fermentation should be clean, filtered and good quality nutrients must be used for the growth of yeasts. Finally, efficiency and yield are calculated and t-test has been performed to depict a direct relationship of the fermentable sugar with efficiency.

Abstract:
An experiment was conducted in Shambat (2012-2013) during the summer and winter seasons to study the stalk-juice quality parameters of 29 exotic and local sweet sorghum varieties as affected by season. The objectives were to provide basic data attributing to syrup and sugar (jaggery) production in the Sudan. The materials were arranged in RCB design. Data were collected on brix, pol (sucrose %), reducing sugars, total sugars, purity and pH. The single and combined analysis of variance revealed highly significant differences among varieties for all traits studied. The variety x season interaction was significant for all traits other than total sugars %, implying the need for considering the variety choice in each season. The results of juice quality parameters were mostly within the range reported in the literature. The exotic materials excelled the local ones in brix, pol%, total sugars% and purity. The exotic varieties: N100, Red-X, Hastings and N110 as well as the local Ankolib selections: AnkNyala and Ank36 were identified as having juice quality traits suitable for syrup production. The exotic varieties: BlueRibbon, KansasCollies and Brawley were identified for sugar (jaggery) production. It was concluded that interaction of variety x season and yield parameters for juice, grain and stover should be considered when determining the choice of the variety. Future research should focus on developing multi-purpose varieties capable for concurrent production of syrup/sugar, grain and stover.

Abstract:
The effectiveness of alkaline hydrogen peroxide as a suitable choice of pretreatment for the conversion of millet husk to reducing sugars using cellulase enzyme for hydrolysis and subsequent ethanol production was determined. The effects of three variables on reducing sugar production from millet husk were determined using one factor at a time (OFAT) method namely; peroxide concentration, pretreatment time and pretreatment temperature. From the results, it was observed that a significant (P<0.05) amount of reducing sugars were lost during pretreatment of millet husk. The untreated group which was only physically pretreated (milled) however yielded a significantly higher (P<0.05) reducing sugar concentration of 10.67mg/ml after enzymatic hydrolysis while the highest reducing sugar concentration of 4.82mg/ml was obtained using 0.375%v/v peroxide concentration for 60minutes at 250C. Therefore, pretreatment of biomass with alkaline hydrogen peroxide may be more suitable for feedstock with high lignin contents than millet husk.

Abstract:
This paper analyzes some chemical pretreatments of sugar beet shreds concerning generated waste flows and yield of reducing sugars obtained by enzymatic hydrolysis of pretreated material. Waste flows produced in pretreatments of sugar beet shreds originated from pectin and lignin removal from raw material. Suitability of substrates prepared in single and two-step pretreatment procedure for enzymatic hydrolysis was determined based on the yield of reducing sugars released by cellulase action on them, while different possibilities of processing of wastewaters were discussed based on the characteristic of waste flows.

Abstract:
Nectar sugar composition and temporal patterns of nectar sugar production were examined in oilseed summer rape (Brassica napus L. ssp. oleifera (Metzg.)) from six open-pollinated, eight pol cytoplasmic male-sterile (CMS) hybrid and seven dominant self-incompatible (SI) hybrid cultivars at three field plot sites in Manitoba. The total sugar content of nectar samples was measured by the Dreywood anthrone reaction for total carbohydrate, and simple sugar composition was determined using an enzymatic bioanalysis for D-glucose, D-fructose and sucrose. Hybrid and open-pollinated cultivar flowers had similar sugar content. Mean total sugar content per flower also did not vary among hybrid breeding systems when compared within individual weeks of the bloom period or within daily sampling periods. However, for all cultivars, total nectar sugar content per flower was lower during the 08:00 and 11:00 h sampling periods and increased to maximum levels during the 14:00 and 16:00 h sampling periods. Significant differences in nectar sugar content were also found in relation to the bloom phenology of the cultivars. Cultivars produced the greatest amount of sugar per flower during the first 2 wk of the bloom period, then sugar production decreased in the third and fourth weeks. Nectar sugar ratios from all cultivars averaged approximately 1:1 glucose:fructose. Nectar glucose content among cultivars was similar but, among breeding systems, CMS cultivars tended to have lower amounts of glucose than SI or open-pollinated cultivars. Selecting for higher total sugar content may produce nectars more attractive to foraging honeybees (Apis mellifera L.), thereby ensuring adequate pollination of hybrid parental lines and F1 hybrid plants. Selecting for lower nectar glucose will produce honeys with more desirable granulation characteristics. Overall, the production and quality of nectar sugar in oilseed rape hybrids are similar to those of open-pollinated cultivars, and are not likely to adversely affect the pollinating activities of honeybees or their potential for honey production.
