Аннотация: The kinetics of polyhydroxyalkanoate (PHA) degradation in natural environment in two water reservoirs having various ecological characteristics was studied. It was shown that biodegradation of polymer essentially depends on the environment temperature and inorganic composition of water. The processes of polymer degradation under aerobic and anaerobic conditions were compared. The polymer degradation was slower under anaerobic conditions. Copyright В© 2008 WILEY-VCH Verlag GmbH & Co.

Аннотация: The study addresses the effect of different conditions of carbon nutrition on synthesis of polyhydroxyalkanoates by the bacterium Wautersia eutropha. In experiments with two wild type strains (H16 and 65786), it has been first found that under mixotrophic growth conditions - Co2 + co-substrate (alkanoic acids) - bacteria can synthesize multi-component PHAs, consisting of short- and medium-chainlength monomers with carbon chains containing 4 to 8 atoms. It has been shown that PHA composition is determined by the type of the co-substrate. Fatty acids with odd number of carbons induce bacteria to synthesize four- and five-component PHAs with hydroxybutyrate, hydroxyvalerate as major monomers and hydroxyhexanoate, hydroxyheptanoate and hydroxyoctanoate as minor, occasionally occurring, ones. Fatty acids with even number of carbons induce synthesis of not only their respective monomers (hydroxyhexanoate and hydroxyoctanoate) but also hydroxyvalerate, making possible synthesis of four-component PHAs, containing hydroxybutyrate and hydroxyhexanoate as major components (up to 18 mol%). A family of short- and medium-chain-length four- and five-component PHAs were synthesized and their physicochemical properties examined. Copyright В© 2008 WILEY-VCH Verlag GmbH & Co. KGaA.

Аннотация: The study addresses the ability of luminous bacteria of different taxa (Photobacterium leiognathi, Photobacterium phosphoreum, Vibrio harveyi, Vibrio fischeri) to synthesize polyesters of hydrocarbon acids (polyhydroxyalkanoates, PHAs) as storage macromolecules. The screened strains widely varied in their PHA productivity. Conditions for attaining high polymer yields (including two- and three-component polymers) in batch culture have been determined. The attained polymer yields reached 40-70% of dry cell biomass. The results suggest a conclusion that luminous microorganisms can be considered as producers of multi-component PHAs.

Аннотация: Physiological-biochemical, genetic, and cultural properties of the glucose-utilizing mutant strain Ralstonia eutropha B8562 have been compared with those of its parent strain R. eutropha B5786. It has been shown that growth characteristics of the strain cultured on glucose as the sole carbon and energy source are comparable with those of the parent strain. Strain B8562 is characterized by high polyhydroxyalkanoate (PHA) yields on different carbon sources (CO2, fructose, and glucose). PHA accumulation in the strain batch cultured on glucose under nitrogen deficiency reaches 90 %. The major monomer in the PHA is ?-hydroxybutyric acid (more than 99 mol %); the identified minor components are ?-hydroxyvaleric acid (0.25-0.72 mol %) and ?-hydroxyhexanoic acid (0.08-1.5 mol %). The strain is a promising PHA producer on available sugar-containing media with glucose. В© Springer-Verlag 2006.

Аннотация: Samples of olyhydroxyalkanoates (PHAs), polyhydroxybutyrate (PHB) and copolymers poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) with 4 and 18 mol% hydroxyvalerate, synthesized by the bacteria Ralstonia eutropha B5786, were investigated. PHA films in contact with blood did not activate the hemostasis system at the level of cell response, but they did activate the coagulation system and the complement reaction. To detect biologically-active components in the PHAs, a detailed analysis of the composition of the polymers was conducted. Gas chromatography-mass spectrometry revealed long-chain fatty acids (FAs) in the tested PHAs. Their total concentration in the polymer ranged from tenths of mol% to 2-3 mol%, depending on the purification method. C16:0 constituted the largest proportion, up to 70%. Of the long-chain hydroxy acids, only ?-OH-C14:0 was detected and it did not exceed 0.06 mol%. The analysis of the hemocompatibility properties of the PHAs purified by a specialized procedure, including the quantitative and morphological estimation of platelets adherent to the surface of polymer films, the plasma recalcification time and complement activation studies, indicated that PHB and PHBV can be used in contact with blood. It has been found out that the lipopolysaccharides of bacteria producing PHAs, which contain mostly long-chain hydroxy acids, can be the factor activating the hemostasis systems. Thus, the technology of PHA purification must satisfy rather stringent specific requirements.

Аннотация: It has been found that the carbon monoxide (CO)-resistant strain of the hydrogen bacteria Ralstonia eutropha B5786 is able to synthesise polyhydroxy-alkanoates (PHAs) in the presence of CO under autotrophic conditions. This strain, grown on model gas mixtures containing 5-25% CO (v/v), accumulates up to 70-75% (of absolutely dry matter) PHA, without significant variation in the yield coefficient on hydrogen. No suppression of the activities of the key enzymes of PHA synthesis (?-ketothiolase, acetoacetyl-CoA-reductase, butyrate dehydrogenase and poly-3-hydroxybutyrate synthase) was recorded. The PHA synthesised is a copolymer containing mostly ?-hydroxybutyrate (more than 99 mol%) with trace amounts of ?-hydroxyvalerate. The investigated properties of the polymer (molecular weight, crystallinity, temperature characteristics) do not differ from those of the polymer synthesised on electrolytic hydrogen.

Заглавие : Production of EPA and DHA in aquatic ecosystems and their transfer to the land
Место публикации : Prostaglandins and Other Lipid Mediators. - 2013. - ISSN 10988823 (ISSN) , DOI 10.1016/j.prostaglandins.2013.03.002
Ключевые слова (''Своб.индексиров.''): aquatic ecosystems--docosahexaenoic acid--eicosapentaenoic acid--trophic transfer efficiency
Аннотация: Most omnivorous animals, including humans, have to some degree relied on physiologically important polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from food. Only some taxa of microalgae, rather than higher plants can synthesize de novo high amounts of EPA and DHA. Once synthesized by microalgae, PUFA are transferred through trophic chain to organisms of higher levels. Thus, aquatic ecosystems play the unique role in the Biosphere as the principal source of EPA and DHA for most omnivorous animals, including inhabitants of terrestrial ecosystems. PUFA are transferred from aquatic to terrestrial ecosystems through riparian predators, drift of carrion and seaweeds, emergence of amphibiotic insects, and water birds. The essential PUFA are transferred through trophic chains with about twice higher efficiency than bulk carbon. Thereby, PUFA are accumulated, rather than diluted in biomass of organisms of higher trophic levels, e.g., in fish. Mankind is faced with a severe deficiency of EPA and DHA in diet. Although additional sources of PUFA supply for humans, such as aquaculture, biotechnology of microorganisms and transgenic terrestrial oil-seed producing plants are developed, natural fish production of aquatic ecosystems will remain one of the main sources of EPA and DHA for humans. Aquatic ecosystems have to be protected from anthropogenic impacts, such as eutrophication, pollution and warming, which reduce PUFA production. В© 2013 Elsevier Inc. All rights reserved.

Аннотация: Bioregenerative life-support systems (BLSS) are studied for developing the technology for a future biological life-support system for long-term manned space missions. Ways to utilize human liquid and solid wastes to increase the closure degree of BLSS were investigated. First, urine and faeces underwent oxidation by Kudenko's physicochemical method. The products were then used for root nutrition of wheat grown by the soil-like substrate culture method. Two means of eliminating sodium chloride, introduced into the irrigation solution together with the products of urine oxidation, were investigated. The first was based on routine electrodialysis of irrigation water at the end of wheat vegetation. Dialysis eliminated about 50% of Na from the solution. This desalinization was performed for nine vegetations. The second method was new: after wheat cultivation, the irrigation solution and the solution obtained by washing the substrate containing mineral elements not absorbed by the plants were used to grow salt-tolerant Salicornia europaea L. plants (saltwort). The above-ground biomass of this plant can be used as a food, and roots can be added to the soil-like substrate. Four consecutive wheat and Salicornia vegetations were cultivated. As a result of this wheat and Salicornia cultivation process, the soil-like substrate salinization by NaCl were considerably decreased. В© 2008 Humana Press.

Аннотация: One of the ways of solving the problem of the human liquid wastes utilization in bioregenerative life support systems (BLSS) can be the use of halophytic vegetable plant Salicornia europaea capable of accumulating sodium chloride in rather high concentrations. Since the most specific higher plant function in BLSS, which at present cannot be substituted by physicochemical processes, appears to be the biosynthesis of a wide spectrum of nutritive substances necessary for a human, the object of the given work was the investigation of the S. europaea productivity, biochemical and mineral composition when grown under close to optimal BLSS vegetative component conditions. As the use of human urine after its preliminary physicochemical processing is supposed to be the mineral solution basis for the S. europaea cultivation, it is necessary to clear up the effect of reduced nitrogen on plants growth. Ground research was carried out. Biochemical composition of the S. europaea edible part showed that crude protein was contained in the highest degree. At that the content of crude protein (24% per dry weight) and cellulose (4.7% per dry weight) was higher in the plants grown on solutions containing amide nitrogen in comparison with the plants grown on solutions with nitrate nitrogen (15.4%-3.1% correspondingly). The water-soluble sugar contents were not high in the S. europaea edible part and depending on the nitrogen nutrition form they amounted to 1.1% (amide nitrogen) and 1.5% (nitrate nitrogen). The polysaccharide number (except cellulose) was rather higher and varied from 7.7% to 8.2%. Although the lipid content in the S. europaea plants was relatively low (7% per dry weight), it was shown that the plant lipids are characterized by a high nonsaturation degree mainly due to alpha linolenic and linoleic acids. Nitrogen nutrition form did not significantly affect the S. europaea productivity, and dry edible biomass of one plant was 8.6 g. Sodium and its concentrations predominated in the plant mineral composition and amounted in average to 9% per dry weight. Thus the S. europaea being the vegetable plant it can be the source of several biochemical substances and essential fatty acids. The present work also considers the influence of nitrate and amide forms of nitrogen on S. europaea biochemical and mineral composition. В© 2008 Elsevier Ltd. All rights reserved.

Ключевые слова (''Своб.индексиров.''): biotechnology--environmental impact--martian surface analysis--photosynthesis--psychophysiology--water pollution--antarctic station--closing technology--ecological life support system--environmental pollution--ecosystems
Аннотация: This closing technology developed for experimental BIOS-3 facility seems to be highly expedient for providing normal life conditions in high-latitude settlements and first of all for life-support of Antarctic stations. Obvious advantages of ecological life-support system based on photosynthesis, in comparison with used now in Antarctic Continent, are: 1) highly effective cascade usage of energy for performance of all functions of life-support; 2) minimization of environmental pollution due to processing human excretions and polluted water; 3) providing crew with fresh vegetable food all-the-year-round; 4) contact with alive plants is powerful source of positive emotions and effective means of psychological relaxation; 5) significant reduction of the transport charges on delivery of foodstuff to Antarctic Continent. First of all, the usage of closed ecosystem can be recommended for high-mountainous station "Concordia". Similar ecosystems can be used in northern high-latitude settlements - Russian North, Canadian Northern territories, Alaska. Finally, the experience of closed ecological life-support system operation in Antarctic Continent can serve as the best range for modeling some aspects of Martian mission - its ecological, biotechnological and psychophysiological problems - since there are no natural conditions on the Earth closer to Mars with respect to severity of a place.

At present, logic schemes of divisions, classification of the objects, presentation of characteristics, and the inputs of relative information, as well as the necessary program modules including links to the database, are developed. The database is constructed on the basis of published data and our own experimental results; the subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only the catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with live genes, as well as to find references and to search strains by using any set of attributes. The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.

Аннотация: The Institute of Biophysics SB RAS hosts and maintains a specialized collection of luminous bacteria (CCIBSO 836) containing over 700 strains isolated in various regions of the world's oceans. The culture collection is a source of lux genes and biologically active substances. The wide application of bioluminescence in medicine and ecology has given importance to analys-ing information on the structure and functioning of bioluminescence systems in natural and transgenic microorganisms, as well as on their features that are closely interrelated with bioluminescence. The aims of our BIOLUMBASE database are: gathering information on microorganisms with lux genes, their analysis and free access, and distribution of this data throughout the global network. The database includes two sections, natural and transgenic luminous microorganisms, and is updated by our own experimental results, the published literature and internet resources. For the future, a publicly available internet site for BIOLUMBASE is planned. This will list the strains and provide comprehensive information on the properties and functions of luminous bacteria, the mechanisms of regulation of bioluminescence systems, constructs with lux genes, and applications of bioluminescence in microbiology, ecology, medicine and biotechnology. It is noteworthy that this database will also be useful for evaluation of biological hazards of transgenic strains. Users will be able to carry out bibliographic and strain searches starting from any feature of interest. Copyright В© 2005 John Wiley & Sons, Ltd.

Аннотация: The database BiolumBase was designed for the collection and systematization of available information on microorganisms containing bioluminescent systems; it includes two sections: natural and transgenic luminous microorganisms. By now, logic schemes of these sections have been developed, classification of the objects has been performed, ways of presentation of characteristics and structure of fields for input of information have been elaborated, and the necessary program modules have been developed. The database is filled on the basis of published data and our own experimental results; subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with lux genes, as well as to find references and to search strains by using any set of attributes.

Аннотация: Growth of Seliberia carboxydohydrogena was inhibited by CO at 10 to 40% (v/v), resulting in increased substrate utilization and enhanced synthesis of cytochromes and cyclopropane and saturated fatty acids. The bacteria showed increased formation of new membrane structures, with pronounced folding of their cell walls. В© 1993 Rapid Communications of Oxford Ltd.

Заглавие : Database of natural luminescent bacteria
Место публикации : Contemporary Problems of Ecology. - 2008. - Vol. 1, Is. 1. - С. 120-126. - ISSN 19954255 (ISSN) , DOI 10.1007/s12259-008-1014-0
Аннотация: The database of luminescent bacteria stored in the IBSO collection is one of the metasections of BIOLUMBASE. A logical schema of the metasection "Natural luminescent organisms", classification of entities, and methods of attribute presentation have been developed. The database of luminescent bacteria maintained in the IBSO collection is being widened by findings of the collection staff as well as by information from scientific literature. The expectant contents of the database will be useful for resolving various problems of microbial ecology and biotechnology which deal with luminescent bacteria, luminescent system derived from them, and lux-genes cloned to other organisms. A potential user would be able not only to access cataloged data on strains but also to get information on properties, functions, use, and bibliography and to perform an attribute-match search of a strain.

Аннотация: This work is a review of the results of biomedical studies of polymer devices (films, fibers, microparticles, 30 implants) made from resorbable PHAs synthesized by the bacterium Wautersia (Ralstonia) eutropha 65786, using the technology developed at the Institute of Biophysics of the Siberian Branch of the Russian Academy of Sciences. Two types of PHAs - polyhydroxybutyrate (PHB) and a hydroxybutyrate/hydroxyvalerate copolymer (PHB/PHV) - have been proven to be biocompatible in vitro in cultures of fibroblasts, endothelial cells, hepatocytes, and osteoblasts, and in short- and long-duration experiments on animals. Polymer films and membranes have been found to be usable as scaffolds for functioning cells and monofilament suture fibers - for stitching muscular-fascial wounds and in abdominal surgery. Ectopic bone formation assay and experiments with the model of segmental osteotomy showed that 30 PHB and PHB/HA implants can be used for reparative osteogenesis. The paper reports beneficial results of using polymers to repair bone defects in oral surgery. Copyright В© 2008 WILEY-VCH Verlag GmbH & Co. KGaA.
