Streszczenie:
Chitosan is increasingly used for safe nucleic acid delivery in gene therapy studies, due to well-known properties such as bioadhesion, low toxicity, biodegradability and biocompatibility. Furthermore, chitosan derivatization can be easily performed to improve the solubility and stability of chitosan–nucleic acid polyplexes, and enhance efficient target cell drug delivery, cell uptake, intracellular endosomal escape, unpacking and nuclear import of expression plasmids. As in other fields, chitosan is a promising drug delivery vector with great potential for the fish farming industry. This review highlights state-of-the-art assays using chitosan-based methodologies for delivering nucleic acids into cells, and focuses attention on recent advances in chitosan-mediated gene delivery for fish biotechnology applications. The efficiency of chitosan for gene therapy studies in fish biotechnology is discussed in fields such as fish vaccination against bacterial and viral infection, control of gonadal development and gene overexpression and silencing for overcoming metabolic limitations, such as dependence on protein-rich diets and the low glucose tolerance of farmed fish. Finally, challenges and perspectives on the future developments of chitosan-based gene delivery in fish are also discussed.

The article presents research based on which the biotechnology of land reclamation in rice crop rotations after fish fallow to improve water and land resources efficiency of rice systems is developed. Irrigation regimes’ influence on rice yield and grain quality was studied. Vegetation experiments and field studies were carried out to establish the place of fish fallow and rice share in the fish/rice crop rotation composition. It is established that after fish fallow the highest Rapan rice variety yield is obtained at shortened and periodic flooding with 5 cm layer up to tillering phase. Under the shortened flooding regime, the qualitative indicators of rice grain and straw in terms of macronutrients content are the best in comparison with other regimes. The most balanced rice irrigation regime under the studied conditions is the regime with periodic flooding with a water layer of 5 cm.

This research analyzes the economic indicators of the fishery complex of the Kaliningrad region in recent years. The introduction of modern biotechnological solutions in the fish processing sector is substantiated. At present, the industry focuses on oceanic and coastal fishing, large fish complexes are leading in fish processing. Food product groups are mainly represented by chilled and frozen semi-finished products. Among food fish products, the production of sterilized canned food predominates; in smaller quantities, preserves, salted, smoked, dried and dried fish products are produced. The fish factories practically do not process fish by-products and there is no production of fish meal. To improve the economic performance of the industry, it is promising to use innovative biotechnologies and advanced foreign experience, which allow processing the extracted raw materials with maximum added value. The Strategy for the Development of the Fisheries Industry of the Russian Federation until 2030, adopted in November 2019, outlines the prospects for the development of marine biotechnology in key segments - aquaculture, production of functional and biologically active products, processing of by-products. The article presents the volumes and problems of fish by-products processing accumulating at fish processing enterprises of the region. A complex scheme of biotechnological by-products processing with the production of valuable biologically active substances (proteins, lipids, mineral substances) is proposed. The technology and production line for the production of protein, protein-mineral and lipid preparations from secondary fish raw materials are described. A modular implementation of biotechnology in marine conditions is proposed. The economic calculation from the introduction of innovative biotechnology in the processing of secondary fat-containing fish raw materials is presented.

Muscle proteins usually provide useful information and therefore are frequently used as valuable diagnostic characters in the classification of fishes at species, generic, familial and higher taxonomic levels. The muscle myogen of four species of carangids. viz, Decapterus russelli, D. macrosoma, Selar crumenophthalmus and Megalaspis cordyla using horizontal slab polyacrylamide gel electrophoresis (Gel conc. 7.5%) is reported in the present communication. The number of protein fractions and the presumptive loci in muscle of D. russelli, D. macrosoma, S. crumenophthalmus and M. cordyla were found to be 9,7,6 and 5 respectively. The Rf value ranged from 21 to 84 for S. crumenophthalmus, 2 to 72 for M cordyla, 15 to 89 for D. macrosoma and 18 to 96 for D. russelli. The difference in number of fractions, their mobility pattern and staining intensity indicated species-specificity. With the limited number of samples used in the present work, there has been an indication of intraspecific polymorphism among three species of carangids, being 3.5% in D. russelli, 13.5% in D. macrosoma and 6.6% in S. crumenophthalmus. In M. cordyla no polymorphism was observed. This work also revealed that protein fractions in carangids can be used as species - specific markers, which could be helpful in resolving disputes in the event of any taxonomic ambiguity.

The electrophoretic profiles of the general proteins and the selected enzymes (MDH and EST) were examined in the green mussel, P. viridis and the brown mussel P. indica and their suspected hybrids from South India. The protein and the enzyme profiles were distinctly different in the two species. The protein profiles in different tissues of the green and brown mussels were found tissue and species specific. The two species are genetically different. The protein and the enzyme profiles in the brown and suspected ‘brown type’ hybrids were similar and that of the green and the suspected ‘green type’ hybrids were also similar. The suspected hybrids may be the colour morphs of the respective species. Morphometric studies on these two species and the suspected hybrids also corroborated the above findings.

Streszczenie:

This thesis covers studies on endogenous proteolytic enzymes and their impact on fish muscle proteins and texture. The studies have been performed using Atlantic salmon (Salmo salar) and cod (Gadus morhua) subjected to different treatments and storage conditions.

The textural properties were very different in the two species. Salmon fillets were significantly softer and less resilient than cod fillets, and the properties changed somewhat differently during storage experiments. Different proteolytic enzymes have been reported to participate in muscle softening. Some of these enzymes were investigated, and specific proteolytic activities were detected throughout the storage periods. Collagenase-like enzymes seem to be the most important for cod muscle texture. Microorganisms and/or microbial enzymes seem not to be important for changes in salmon muscle texture. Results suggest that the cathepsin B-like enzymes are important for salmon texture. The activities of the proteolytic enzymes may be greatly affected by the muscle pH, and by the treatment(s) the fish are subjected to. In any case, changes caused by differences in proteolytic activities may need some time to be detectable or have significant impact on fish quality.

When cod fillets are stored in ice, it is highly recommended to keep the temperature low. Even a relatively mild temperature abuse was sufficient to result in less favorable textural characteristics, and make the fillets seem older than their days of storage.

Salmon fillets are often subjected to cold-smoking. The smoking temperature was important for the solubility properties of the muscle proteins, and for their composition, but did not affect the proteolytic activity. The effects of the processing parameters were most important early in the product’s shelf life, as the differences caused by the different smoking temperatures were reduced by further storage of the smoked samples.

Zygomycetes is a class of fungi living worldwide as saprobes, as part of mycorrhizae, and as parasites. Humans have used some zygomycetes for centuries in the production of traditional foods, e.g. Indonesian tempe. In the present thesis, the experimental focus was on two zygomycetes strains, Mucor indicus CCUG 22424 and Rhizopus sp. IT. One of the distinguishing features of M. indicus is its dimorphism. The different cell forms were influenced by the culturing conditions. After inoculation, when the initial spore concentration was high (6-8×106 spores/ml), yeast-like growth dominated under anaerobic conditions. With a smaller inoculum, yielding 1-2×105 spores/ml, and access to oxygen, filamentous forms dominated. Only negligible differences in ethanol yield (390-420 mg/g hexoses), productivity (3-5 g/l/h), and inhibitor tolerance were observed. Differential expressions of probably four genes were observed between the yeast-like and filamentous growth forms. Lignocelluloses are a suitable substrate for cultivating zygomycetes, as they occur in abundance, particularly since zygomycetes, unlike Saccharomyces cerevisiae, can utilise pentoses. Lignocelluloses require pretreatment to achieve efficient hydrolysis of the cellulose. N-methylmorpholine-N-oxide (NMMO) was tested for pretreatment of spruce and birch. Reducing wood chip size and/or prolonged pretreatment, promoted hydrolysis yield. Best yields were achieved from <2 mm chips and 5 h pretreatment. The hydrolysate was used for fermentation with M. indicus, resulting in 195 and 175 mg ethanol/g wood, and 103 and 86 mg fungal biomass/g wood, from spruce and birch respectively. Orange peel is another potential substrate. However, the hydrolysate contained 0.6 % (v/v) D-limonene, ten times higher than the concentration inhibiting S. cerevisiae. M. indicus was more resistant and successfully fermented the hydrolysate, producing 400 mg ethanol/g hexoses and 75 mg fungal biomass/g sugars. Both M. indicus and Rhizopus sp. grew in 1.0 % and 2.0 % D-limonene, although the latter was unable to grow in the hydrolysate. A third substrate was also used, spent sulphite liquor (SSL), which is a by-product from sulphite paper pulp mills. The SSL was diluted to 50 % and used for airlift cultivations of Rhizopus sp. In 1.0 vvm aeration, up to 340 mg biomass/g sugars was produced. Prolonged cultivations generally decreased the protein (from 500 to 300 mg/g) and lipid (from 70 to 20 mg/g) contents. In contrast, the cell wall fraction, measured as alkali-insoluble material (AIM), increased (160-280 mg/g), as did the glucosamine (GlcN) content (220-320 mg GlcN/g AIM). The produced fungal biomass could serve as animal feed, e.g. for fish.

Nos vertebrados, a espermatogênese é um processo de desenvolvimento celular altamente conservado e organizado, no qual uma pequena população de espermatogônias tronco produz continuamente milhões de espermatozóides, os quais são os responsáveis pela propagação do genótipo dos machos. Este processo é sustentado pelas espermatogônias tronco através da sua capacidade de auto-renovação e diferenciação. Vários aspectos relacionados com a regulação da atividade e fisiologia das espermatogônias tronco são ainda desconhecidos nos peixes teleósteos. Portanto, a técnica de transplante de células germinativas torna-se uma poderosa abordagem para melhorar o conhecimento da biologia das espermatogônias tronco e da espermatogênese. Resumidamente, a técnica envolve a transferência de células germinativas isoladas de um doador fértil para os testículos de um receptor estéril, e as células transplantadas são capazes de restaurar a gametogênese do receptor. Neste contexto, realizamos uma caracterização morfológica e estereológica dos diferentes tipos de células encontradas na espermatogênese da carpa comum (Cyprinus carpio). Também caracterizamos fenotipicamente as potenciais espermatogônias tronco. Portanto, descrevemos cinco tipos espermatogôniais na carpa comum: espermatogônias indiferenciadas do tipo A (Aund* - Aund), espermatogônias diferenciadas do tipo A (Adiff) e espermatogônias do tipo B (inicial e final). Nesta espécie, o processo espermatogênico durou aproximadamente uma semana. Nossos resultados demonstraram que a população espermatogonial expressa as proteínas c-Kit, Gfrα-1 e POU2. Neste estudo, também foi padronizada a técnica de transplante de espermatogônias na carpa comum. Assim, células germinativas isoladas de kinguios sexualmente maduros foram transplantadas através da papila urogenital de carpas macho quimicamente esterilizadas. As células germinativas derivadas dos doadores foram capazes de colonizar e se desenvolver nos testículos dos receptores. Em geral, nossos resultados reforçam a compreensão da biologia das células germinativas, em especial das potenciais células tronco. Além disso, o transplante, padronizado aqui, é uma abordagem com implicações significativas para a conservação e manejo das espécies valiosas e/ou ameaçadas de extinção.
In vertebrates, spermatogenesis is a highly conserved and organized developmental process, in which a small population of spermatogonial stem cells (SSC) continuosly produce millions of spermatozoa, which are responsible for spreading the male genotype. Likewise other stem cells, SSC are capable of either self-renew or differentiate. Several aspects related to the regulation of SSC activity and physiology are still unknown in teleost fish. Thus, the germ cell transplantation technique becomes a powerful approach to improve the knowledge of SSC biology and spermatogenesis. Briefly, the technique involves the transfer of germ cells isolated from a fertile donor into the testes of a sterile recipient, and transplanted donor germ cells are able to restore the recipient gametogenesis. Taking advantage of this background, we performed morphological and stereological characterization of the different cell types found in the common carp (Cyprinus carpio) spermatogenesis. We also characterized the putative SSC candidates by morphology. Therefore, we described five spermatogonial types in common carp: type A undifferentiated spermatogonia (Aund* - Aund), type A differentiated spermatogonia (Adiff) and type B spermatogonia (early and late). In this species, the spermatogenic process lasted approximately one week. Our findings demonstrated that the spermatogonial population expressed the c-Kit, Gfrα1 and POU2 proteins. Donor germ cells isolated from goldfish were transplanted non-surgically through urogenital papilla into the sexually mature cytoablated common carp recipients. Donor transplanted germ cells were able to colonize and develop in recipients’ testes. Overall, our results strengthens the knowledge of germ cell biology, focusing on stem cells. Finally, transplantation, standardized here, is an approach with significant implications for the conservation and management of endangered and valuable fish species.

Streszczenie:
La biofiltración ha demostrado ser una tecnología exitosa para la eliminación del H2S y del NH3 de las corrientes de gases contaminadas. El tema asume relevancia pues se establece como tecnología limpia y sostenible. Debido a su organización los biofiltros son considerados ecosistemas artificiales complejos en donde las variables ambientales y la composición de la comunidad están estrictamente relacionadas y de ellas depende el éxito del proceso. La diversidad de bacterias y la dinámica de la comunidad son elementos importantes del componente biológico aunque su conocimiento es aún muy limitado. Para comprenderlo mejor se necesitan perfiles poblacionales elaborados mediante herramientas de biología molecular tales como la pirosecuenciación e hibridación con fluorescencia in situ (FISH). Este fue el eje temático de la presente tesis: Estudiar la composición y la dinámica de comunidades de Eubacteria de biofiltros percoladores mediante pirosecuenciación 454-Roche (tag-454). También se procedió a optimización de protocolos FISH. Para ambas herramientas se evaluó la cobertura de la diversidad y su efectividad para el estudio y seguimiento del componente biológico.Se estudiaron dos sistemas de desulfuración de biogás, uno aerobio y otro anóxico, y un tercer sistema de tratamiento de corrientes ricas en NH3. Los resultados obtenidos demostraron que la comunidad fue capaz de sostenerse bajo las condiciones de operación probadas. En el biofiltro de desulfuración aerobia ocurrió un cambio drástico en la composición de la microbiota en función de la acidificación del medio (pH; 7-2.5), y que la pérdida de diversidad fue compensada por la eficacia de las poblaciones acidófilas. En el biofiltro anóxico los cambios poblacionales no afectaron, en general, en el rendimiento de la desulfuración del biogas, y la actividad de Sedimenticola fue determinante para el éxito del sistema. En el biofiltro percolador de NH3 se comprobó los efectos combinados de tiempos de residencia con diferentes concentraciones de entrada del gas. Las alteraciones en dichos parámetros produjeron cambios significativos en la comunidad nitrificante. Las condiciones favorecieron el crecimiento de Comamonas, Nitrosomonas (AOB) y Nitrobacter (NOB). Fue interesante encontrar una presencia marcada de bacterias desnitrificantes, cosa que no perjudicó al rendimiento de la nitrificación. En los estudios con tag-454 se encontró dificultad a la hora de asignar identidad a secuencias, lo que se justificó por la longitud insuficiente de los fragmentos y por la falta de cobertura de las bases de datos. De todos modos los resultados indicaron que la diversidad fue representada adecuadamente, permitiendo una cobertura muy buena de las distintas comunidades hecho que corrobora la efectividad de la aproximación. El trabajo de optimización de la FISH se enmarca en el conocimiento previo de la diversidad microbiológica a la hora de elegir sondas y se comprobó la influencia de la autofluorescencia del S0 sobre el recuento de células. Los resultados mostraron que la elección de los fluorocromos fue fundamental para eliminar la autofluorescencia de las partículas de S0 que originaban datos sobre-estimados de abundancia relativa.
Biofiltration has proved to be a successful technology for removal of H2S and NH3 from the contaminated gases. The subject assumes significance as it is established as a clean and sustainable technology. Due to its organization biofilters are considered complex artificial ecosystems, where environmental variables and community composition are strictly related and on them depends the success of the process. The bacterial diversity and community dynamics are very important elements of the biological component, but their knowledge is still very limited. To better understand it, populational profiles elaborated by tools such as molecular biology and genomic DNA pyrosequencing of fluorescence in situ hybridization (FISH) are required. This was the theme of this thesis: To study the composition and dynamics of Eubacteria communities in three trickling biofilters using the 454-Roche (tag-454). FISH protocols were also optimized. Two systems of biogas desulphurization were studied, one aerobic and one anoxic, plus a third system for treatment of currents rich in NH3 . The acquired results showed the ability of the community to sustain itself under the tested operational conditions. In the aerobic biofilter desulfurization it occurred a drastic change in the composition of the microbiota in terms of environmental acidification; (pH; 7-2.5), and that biodiversity loss was offset by the effectiveness of acidophilic populations. In the anoxic biofilter, changes did not affect the population in general, the performance of biogas desulfurization and Sedimenticola activity was crucial to the success of the anoxic desulfurization. In the NH3 trickling biofilter, it was proved the combined effects of residence time and different concentrations of gas entrance. Alterations in said parameters produced meaningful changes in the nitrifying community. The resulting conditions favored the growth of the Comamonas, Nitrosomonas (AOB) and Nitrobacter (NOB). It was interesting to find a strong presence of denitrifying bacteria, which did not affect the nitrification performance. In studies using tag-454, the difficulty of assigning identity to the readings of some of the found sequences, which was justified by the insufficient length of the fragments and the lack of databases coverage. Regardless, the results indicated that the diversity represented the 95% of similarity, and in the end there was a very good coverage of different communities. The relative abundance data allowed the explanation of the dynamics of said communities, fact that corroborates the approximation’s efficiency. The optimization of work by FISH relays in prior knowledge of microbial diversity when choosing probes, and proved the influence of the S0 autofluorescence over the cell count. The results showed that the choice of fluorochromes was fundamental to eliminate the autofluorescence of S0 particles that originated over-estimated data of relative abundance.

The growing demand for aquaculture feed of excellent nutritional quality to maximize the performance of animals raised. However, stagnation and decreased availability of ingredients that fulfill the nutritional requirements of the fish depend on both the nutritional equivalent substitutes as financial environment. Thus, this study aims to evaluate the inclusion of fish protein hydrolyzate in diets for fingerlings of Nile tilapia Oreochromis niloticus. 300 fish (5.4 ± 0.9 g) were distributed in a completely randomized in 20 polythene containers of 250 L with five treatments and four replicates were used design. Vegetable diets were formulated to be isonitrogenous and isocaloric consists of corn, corn gluten meal, wheat bran, soybean meal and soybean oil were added and the levels of hydrolyzed fish and one control diet (0%) and four test feed containing 1, 2, 3 and 4% fish protein hydrolyzate, based on dry matter. The animals were fed to satiation four times daily for 112 days. At the end of the experimental period, the animals were measured and weighed to determine the final weight, total length, survival rate, weight gain, specific growth rate, feed conversion ratio and condition factor. Levels hydrolyzed influenced the productive aspects of the Nile tilapia, which by quadratic regression we estimate the optimal inclusion of 1.79% for final weight, 1.77% to gain weight, 1.75% to rate and the specific growth rate to 1.97% protein efficiency. However, it is suggested to Nile tilapia inclusion of 1.78% of fish protein hydrolyzate for better productive performance.
O crescimento da aquicultura demanda por rações de excelente qualidade nutricional que maximizem o desempenho dos animais criados. No entanto, a estagnação e diminuição da disponibilidade de ingredientes que supram as necessidades nutricionais dos peixes dependem de substitutos equivalentes tanto no contexto nutricional quanto financeiro. Dessa forma, o presente estudo visa avaliar a inclusão de hidrolisado proteico de pescado em dietas para alevinos de tilápia do Nilo Oreochormis niloticus. Foram utilizados 300 peixes (5,4 ± 0,9 g), distribuídos em um delineamento inteiramente casualizado em 20 caixas de polietileno de 250 L com cinco tratamentos e quatro réplicas. As rações vegetais foram formuladas de forma a serem isoproteicas e isoenergéticas constituída por milho, glúten de milho, farelo de trigo, farelo de soja e óleo de soja e foram acrescidas de níveis de hidrolisado de pescado sendo uma ração controle (0 %) e quatro rações teste contendo 1, 2, 3 e 4% de hidrolisado proteico de pescado, com base na matéria seca. Os animais foram alimentados até a saciedade aparente quatro vezes ao dia por 112 dias. Ao término do período experimental, os animais foram medidos e pesados para determinação do peso final, comprimento total final, taxa de sobrevivência, ganho em peso, taxa de crescimento específico, conversão alimentar aparente e fator de condição. Os níveis de hidrolisado influenciaram os aspectos produtivos dos alevinos de tilápia do Nilo, onde através da regressão quadrática estima-se a inclusão ótima de 1,79% para peso final, 1,77% para ganho em peso, 1,75% para taxa de crescimento especifico e 1,97% para taxa de eficiência proteica. Contudo, sugere-se para alevinos de tilápia do Nilo a inclusão de 1,78% de hidrolisado proteico de pescado para melhor performance produtiva.

Streszczenie:
Hypoxia inducible factors (HIFs) are transcription factors and the master regulators of oxygen-dependent gene expression in animals. The focus of this thesis is the distribution of HIF protein in tissues of the fish Fundulus heteroclitus and F. grandis, two widespread species that occur in naturally hypoxic waters. Polyclonal antibodies against HIF-1α, HIF-2α, and HIF-3α were tested on proteins made in vitro and on extracts made from several tissues of normoxic and hypoxic fish. Antibodies against HIF-1α and 3α bound specifically to full length protein made in vitro, and produced bands on western blots of nuclear extracts of near the expected molecular weights for these proteins. Hypoxic exposure did not markedly increase the intensity of these bands, and mass spectrometry failed to identify HIF-1α and 3α peptides in excised gel bands. Thus, further tests of antibody specificity are needed before the tissue distribution of HIF in these fish can be confidently assessed.

Streszczenie:
Biotechnology is a field in great expansion and the continuous boost for obtaining smaller and more efficient devices stimulates the increase of interest from the research community. Nanostructured materials, and among them porous silicon (PS), appear to be good candidates for coupling with biological molecules because of their peculiar characteristics. In the case of porous silicon, the most noticeable are the very large specific area, which allows the loading of large amounts of biological material in a very small volume, and the possibility to easily tailor the pore size and morphology as function of the kind of molecules to be introduced. Besides, the proven biocompatibility and non toxicity of PS allow the development of electronic devices to be directly implanted into living organisms without risk of rejection. In this thesis we mainly focus our attention on the fabrication and characterization of a porous silicon-based potentiometric biosensor for triglycerides analysis, made of a lipase immobilized on a mesoporous Si matrix. Prototypes, realized on 1 x 1 cm n+-type silicon wafers, show a very high enzymatic activity. Moreover the properties of these biosensors have been shown to be stable in a several months time interval, clearly showing their advantages with respect to traditional triglycerides detection systems. The Michaelis Menten curve is obtained to demonstrate the absence of diffusion problems. Potentiometric measurements are also shown.
