Аннотация: Biodegradation of film specimens from polyhydroxyalkanoates (PHAs) of two types - poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3- hydroxyvalerate (PHBV) - was analysed in different environments: tropical sea waters of the South China Sea (Nha Trang, Vietnam) and soils in the environs of Hanoi (Vietnam), Nha Trang (Vietnam) and Krasnoyarsk (Siberia, Russia). In seawater, the mass loss of the specimens of both types was almost equal. However, in tropical soils, PHB degraded quicker than PHBV. In the Siberian soil, the degradation rate of the PHBV was generally higher than that of PHBV. Analysis of molecular mass of PHA specimens showed its decreasing during biodegradation. In the tropical sea conditions, PHA degrading microorganisms were represented by bacteria of Enterobacter, Bacillus and Gracilibacillus genera. Among PHA degrading bacteria, Burkholderia, Alcaligenes, Bacillus, Mycobacterium and Streptomyces genera were identified in Vietnamese soils, and Variovorax, Stenotrophomonas, Acinetobacter, Pseudomonas, Bacillus and Xanthomonas genera in Siberian soils. Micromycetes of Gongronella, Paecilomyces, Penicillium and Trichoderma genera exhibited PHA degrading activity in Vietnamese soils, and Paecilomyces, Penicillium, Acremonium, Verticillium and Zygosporium genera - in Siberian soils.

Заглавие : Characteristics of proteins synthesized by hydrogen-oxidizing microorganisms
Место публикации : Applied Biochemistry and Microbiology. - 2010. - Vol. 46, Is. 6. - С. 574-579. - ISSN 00036838 (ISSN) , DOI 10.1134/S0003683810060037

Аннотация: The study was conducted to determine the biological value of proteins synthesized by hydrogen-oxidizing microorganisms-the hydrogen bacteria Alcaligenes eutrophus Z1 and Ralstonia eutropha B5786 and the CO-resistant strain of carboxydobacterium Seliberia carboxydohydrogena Z1062. Based on a number of significant parameters characterizing the biological value of a product, the proteins of hydrogen-oxidizing microorganisms have been found to occupy an intermediate position between traditional animal and plant proteins. The high total protein in biomass of these microorganisms, their complete amino acid content, and availability to proteolytic enzymes allow for us to consider these microorganisms as potential protein producers.

Заглавие : Cloning and molecular organization of the polyhydroxyalkanoic acid synthase gene (phaC) of Ralstonia eutropha strain B5786
Место публикации : Applied Biochemistry and Microbiology. - 2010. - Vol. 46, Is. 2. - С. 140-147. - ISSN 00036838 (ISSN) , DOI 10.1134/S0003683810020031

Аннотация: Class I polyhydroxyalkanoic acid (PHA) synthase gene (phaC) of Ralstonia eutropha strain B5786 was cloned and characterized. R. eutropha B5786 features the ability to synthesize multicomponent PHAs with short- and medium-chain-length monomers from simple carbohydrate substrate. A correlation was made between the molecular structure of PHA synthase and substrate specificity and the ability of strain-producers to accumulate PHAs of this or that structure. A strong similarity of PHA synthase of R. eutropha strain B5786 with PHA synthase of R. eutropha strain H16, which, as opposed to strain B5786, enables to incorporate medium chain length PHAs if hexanoate is used as carbon source, exhibited 99%. A correlation between the structure of PHA synthase of B5786 strain with synthases of microorganisms which synthesize short and medium chain length PHAs similarly to B5786 strain, showed an identity level from 26 to 41% (homology with synthase of Rhodospirillum rubrum makes 41%, Ectothiorhodospira shaposhnikovii makes 26%, Aeromonas punctata makes 40%, Thiococcus pfennigii makes 28%, Rhodococcus ruber makes 38%, and with PhaCl and PhaC2 synthases of Pseudomonas sp. 61-3 makes 34 and 37%, respectively). This allows for speaking about the absence of a direct connection between the molecular organization of PHA synthases and their functional abilities, namely, the ability to synthesize PHAs of a particular composition.

Заглавие : Testing soil-like substrate for growing plants in bioregenerative life support systems
Место публикации : Advances in Space Research. - 2005. - Vol. 36, Is. 7. - С. 1312-1318. - ISSN 02731177 (ISSN) , DOI 10.1016/j.asr.2005.05.079

Аннотация: We studied soil-like substrate (SLS) as a potential candidate for plant cultivation in bioregenerative life support systems (BLSS). The SLS was obtained by successive conversion of wheat straw by oyster mushrooms and worms. Mature SLS contained 9.5% humic acids and 4.9% fulvic acids. First, it was shown that wheat, bean and cucumber yields as well as radish yields when cultivated on mature SLS were comparable to yields obtained on a neutral substrate (expanded clay aggregate) under hydroponics. Second, the possibility of increasing wheat and radish yields on the SLS was assessed at three levels of light intensity: 690, 920 and 1150 ?mol m-2 s-1 of photosynthetically active radiation (PAR). The highest wheat yield was obtained at 920 ?mol m-2 s-1, while radish yield increased steadily with increasing light intensity. Third, long-term SLS fertility was tested in a BLSS model with mineral and organic matter recycling. Eight cycles of wheat and 13 cycles of radish cultivation were carried out on the SLS in the experimental system. Correlation coefficients between SLS nitrogen content and total wheat biomass and grain yield were 0.92 and 0.97, respectively, and correlation coefficients between nitrogen content and total radish biomass and edible root yield were 0.88 and 0.87, respectively. Changes in hormone content (auxins, gibberellins, cytokinins and abscisic acid) in the SLS during matter recycling did not reduce plant productivity. Quantitative and species compositions of the SLS and irrigation water microflora were also investigated. Microbial community analysis of the SLS showed bacteria from Bacillus, Pseudomonas, Proteus, Nocardia, Mycobacterium, Arthrobacter and Enterobacter genera, and fungi from Trichoderma, Penicillium, Fusarium, Aspergillus, Mucor, Botrytis, and Cladosporium genera.

Заглавие : Wheat growth on neutral and soil-like substrates: Carbon dioxide exchange and microflora
Место публикации : Acta Horticulturae. - 2004. - Vol. 644. - С. 243-248
Ключевые слова (''Своб.индексиров.''): carbon dioxide--closed ecological system
Аннотация: The soil-like substrate (SLS), which is a potential candidate for employment in closed ecological systems, has been tested. CO2 exchange, composition and numbers of soil microflora have been examined in .wheat-SLS. system. The results produced have been compared to analogous characteristics of .wheat-neutral substrate. system. A hydroponic method was used under wheat growing on the neutral substrate (expanded clay aggregate). Plants for both studies were grown in closed environment from seed to physiological maturity. In the .wheat-SLS. system, the net photosynthetic rate of canopy was positive in the course of 6.55 days after planting. The net photosynthetic rate of canopy in .wheat-neutral substrate. system was positive in the entire course of vegetation. According to calculations in the course of vegetation, photosynthesis has withdrawn 3.28 kg m-2 CO2 from the .wheat-SLS. system and 3.40 kg m-2 CO2 from the .wheat-neutral substrate. system. On the SLS dominant among bacteria were the spore-forming bacteria from Bacillus genus, among fungi . from Trichoderma genus. In the hydroponic cultivation on neutral substrate dominant were bacteria from Pseudomonas genus, most commonly found fungi were species from Fusarium and Botrytis genera.

Ключевые слова (''Своб.индексиров.''): co2-enrichment--ecosystem--plant--rhizospheric microorganisms
Аннотация: A mathematical model describing the interaction of plants and rhizospheric microorganisms on complete mineral medium at a higher CO2 level in the atmosphere was constructed. The positive effect of CO2-enrichment on the system plant - rhizospheric microorganisms was shown. The effect of rhizospheric microorganisms on plant growth at normal and high level of carbon dioxide was demonstrated. It was shown that the biomass of plant in the system is smaller than the biomass of plant growing without microorganisms. It was experimentally demonstrated that a simple ecosystem wheat - Pseudomonas putida - artificial soil develops and functions differently than its individual constituents in the case of a wheat-artificial soil system. With unlimited nutrition and a higher CO2 level (0.06%), plants with roots inoculated with microorganisms have a smaller biomass than plants that were not inoculated with microorganisms.

Заглавие : On monitoring the bacterial component as an indicator of the state of small man-made ecosystems

Аннотация: High reproduction rates make the bacterial component of ecosystems a good indicator of the state of the system on the whole. This determines the necessity to develop rapid monitoring of the functional state of the bacterial component of small ecosystems. Information about substrate concentration in the population is indicative of the state of the bacterial culture. Conventional methods of monitoring the concentration of integral substrate in the system take time much longer than the changes in the ecosystem. The paper presents theoretical foundations for the logical sequence "catalase activity - intracellular substrate concentration - estimate of substrate consumed by bacteria" for experimental verification and as a consequence of development of the integral method of monitoring the bacterial population on the basis of determining bacterial catalase activity.

Аннотация: Effect of the size of rhizospheric bacterial populations on germination of seeds and development of simple terrestrial "wheat plants - rhizospheric microorganisms - artificial soil" and "wheat plants - artificial soil" systems has been studied. Experiments demonstrated that within specify ranges in the inoculate, the rhizospheric bacteria are capable of increasing the yield of germinated seeds and stimulate the growth of plantlets. Germination of seeds inoculated with bacteria was either stimulated, or inhibited or remained at control levels depending on the amount of bacteria. Plant biomass growth and total photoassimilation has been found to depend on the amount of bacteria on the plant roots: the higher the amount of bacteria on plant roots, the smaller is the biomass of plants but the total photoassimilation is, higher. Thus, depending on the amount of bacteria on the roots of plants the system either increases the biomass of plants or increases the total photoassimilation, i.e. "pumps" carbon through itself involving bacteria.

Ключевые слова (''Своб.индексиров.''): biomass--growth--nitrogen--pseudomonas--transpiration--wheat
Аннотация: The influence of two rhizosphere bacteria-Pseudomonas fluorescens and Pseudomonas putidaon the growth of wheat seedlings was studied under conditions of complete mineral supply and nitrogen deficiency in the medium. On complete mineral medium, the plants that developed from the seeds inoculated with the pseudomonads had some advantages for growth over those developed from the non-inoculated seeds. Inoculated plants showed an increased transpiration and a higher content of organic nitrogen in their biomass. Under conditions of nitrogen deficiency in the medium, no differences were found between inoculated and noninoculated plants. No competition for the nitrogen sources was revealed between the bacteria and plants; the development of the rhizosphere bacteria was limited by the rate of organic compound excretion by plant roots. The stimulatory effect produced on plant growth by the rhizosphere bacteria was shown to vary depending on the environmental factors.

Аннотация: The effect has been studied of inoculation of seeds of wheat with two species of rhizospheric microorganisms, -Pseudomonas fluorescens and Pseudomonas putida - on young plant growth with complete and with nitrogen deficit mineral nutrition. With complete mineral medium, plants grown from seeds inoculated with bacteria of Pseudomonas genus (experiment plants) have been found to have better growth over plants not inoculated with these bacteria (control plants). The experiment plants had increased transpiration and their biomass had higher organic nitrogen content. With nitrogen deficit medium, the plants inoculated with bacteria and those without them, have not revealed changes in growth. Neither case demonstrated competition of microorganisms with plants for nitrogen sources. В© 1997 COSPAR. Published by Elsevier Science Ltd.

Аннотация: A mathematical model concerning the interaction of plants and rhizospheric microorganisms on complete mineral medium and under nitrogen limitation has been constructed. The model takes into account the closeness of plants and microorganisms in terms of the matter released by the plant and consumed by the microorganisms. The effect of rhizospheric microorganisms on plant growth with normal carbon dioxide and complete mineral medium has been demonstrated. Plants interacting with microorganisms have a greater biomass than plants growing without microorganisms. Wheat growth stimulation by metabolites of rhizospheric microorganisms under laboratory conditions on artificial soil has been experimentally demonstrated (Pechurkin, 1997). Under nitrogen limitation , the biomass of plants, with or without microorganisms, is identical, and is substantially reduced as compared with the medium with standard nitrogen. В© 1999 COSPAR.

Аннотация: Response of "wheat plants--rhizospheric microorganisms--artificial soil"--a simple terrestrial ecosystem--to carbon dioxide increased in its atmosphere to 0.06% has been studied. It has been experimentally demonstrated that a simple ecosystem develops and functions different from its individual elements (components), in this case "plants-artificial soil" without microorganisms. With mineral nutrition unlimited and CO2 enrichment the system is capable of binding (involving into turnover) 40% more carbon than the system without microorganisms. With material balance as the basis, this article evaluates the contribution of a system's elements into its development, namely, the contribution of the photosynthesizing component and the contribution of microorganisms.

Аннотация: Изучено влияние двух видов ризосферных микроорганизмов Pseudomonas fluorescens и Pseudomonas putida на рост молодых растений пшеницы в условиях полного минерального питания и при дефиците азота в среде. Показано, что на полной минеральной среде растения, семена к-рых были инокулированы бактериями рода Pseudomonas (опытные растения), имели ростовые преимущества по сравнению с растениями, не инокулированными этими бактериями (контрольные растения). У опытных растений возрастала интенсивность транспирации, в биомассе растений было более высокое содержание органического азота. При дефиците азота в среде не отмечено изменений ростовых характеристик растений, инокулированных бактериями и без них. Не обнаружено конкуренции микроорганизмов с растениями за источники азота, так как лимитирующим фактором развития ризосферных микробов являлась скорость поступления органических веществ с корневыми эксудатами. Показано дифференцированное влияние ризосферных микроорганизмов на рост растений в зависимости от факторов среды

Аннотация: Изучена реакция простой наземной экосистемы "пшеница-ризосферные микроорганизмы-искусственная почва" на повышение содержания диоксида углерода в атмосфере до 0,06%. В этих условиях у растений, инокулированных ризосферными бактериями (Pseudomonas), скорость фотосинтеза повышается на 30% по сравнению с растениями, семена которых были не инокулированы бактериями. В системе с нормальным содержанием CO[2] в атмосфере (0,03%) скорость фотосинтеза у растений, инокулированных бактериями, увеличивается только на 10%. В экспериментах оценен вклад микроорганизмов в развитие системы. Растения с микроорганизмами в системе вовлекают в круговорот на 40% углерода больше, чем растения без микроорганизмов. При этом более 30% углерода, ассимилированного в системе, через корневые эксудаты идет на рост и дыхание микроорганизмов. Россия, Ин-т биофизики СО РАН, 660036 Красноярск, Академгородок

Аннотация: Построена математическая модель, описывающая взаимодействие растений и ризосферных микроорганизмов на полной минеральной среде при повышенном содержании CO[2] в атмосфере. Показано положительное действие повышенного содержания CO[2] на систему растение - ризосферные микроорганизмы. С помощью модели продемонстрировано влияние ризосферных микроорганизмов на рост растений. Показано, что биомасса растений в системе растение - ризосферные микроорганизмы меньше биомассы растений без микроорганизмов. На примере простой экосистемы пшеница - Pseudomonas putida - искусственная почва экспериментально подтверждено, что на минеральной среде (без лимита по азоту) при повышенном содержании CO[2] (0,66%) биомасса растений, корни которых инокулированы микроорганизмами, меньше биомассы растений без инокуляции микроорганизмами.

Аннотация: The natural microflora of Middle Siberian karst cavities, which comprises psychrotolerant bacteria and fungi capable of growing at 3-15 and 3...+28В°C, respectively, has been studied. Bacteria are ubiquitous in caves, their count varying from 103 to 107 cells/g ground. The bacteria have been identified as Pseudomonas, Arthrobacter, Bacillus, and coryneform bacteria. Fungi have been found in places exposed to increased anthropogenic impact, their count being as large as 106 to 107 cells/g ground. Mucor, Penicillium, and Chrysosporium were dominant fungal genera.

Аннотация: Исследовали естественную микрофлору карстовых полостей Средней Сибири, представленную психрофильными и психротолерантными бактериями и грибами, способными к росту при т-ре +3...+15'ГРАДУС'C и +3...+28'ГРАДУС'C соответственно. Бактерии в пещерах распространены повсеместно, их численность колеблется от 10{3} до 10{7} клеток/г грунта. Идентификация показала наличие родов Pseudomonas, Arthrobacter, Bacillus и коринебактерий. Грибы встречаются в местах с повышенной антропогенной нагрузкой, их численность достигает 10{6}-10{7} колониеобразующих единиц/г грунта. Среди грибов доминируют представители родов Mucor, Penicillium, Chrysosporium. Россия, Красноярский гос. аграрный ун-т, Красноярск. Библ. 12
