Новый штамм уксуснокислых бактерий Komagataeibacter xylinus B-12068 – продуцент бактериальной целлюлозы для биомедицинского применения

The strain of acetic acid bacteria Komagataeibacter xylinus B-12068, producing of bacterial cellulose (BC), was isolated and described. The effects of cultivation conditions (carbon sources, temperature, and pH) on BC production and properties were studied in surface and submerged cultures. Glucose was found to be the best substrate for BC production among the sugars tested; ethanol concentration of 3 % (w/v) enhanced the productivity of BC. The highest BC yield (up to 17.0 g/L) was obtained under surface static cultivation conditions, in the modified HS medium supplemented with ethanol, at pH 3.9, after 7 days of cultivation in the thinnest layer of the mediumВыделен и описан штамм уксуснокислых бактерий Komagataeibacter xylinus B-12068, продуцент бактериальной целлюлозы (БЦ). Изучено влияние условий выращивания штамма (источники углерода, температура и рН) в поверхностном и глубинном режимах на выход и свойства БЦ. Показано, что из спектра сахаров глюкоза является лучшим субстратом для получения БЦ; этанол в концентрации 3 % (w/v) стимулирует синтез БЦ. Максимальная продукция БЦ (до 17.0 г/л) получена при поверхностном статическом культивировании штамма в течение 7 сут при рН 3.9 на модифицированной среде HS с добавками этанола при минимальном слое сред

The Effect of Different Concentrations of Energia-M Growth Regulator on the Growth and Development of Solánum tuberósum L. plants

The analysis of the available bibliographic data on the influence of silicon and its compounds on physiological processes in plants was carried out. The purpose of the work was to determine the effect of the organosilicon growth regulator Energia-M in concentrations of 10, 50, 80 mg/l on the growth and productivity of the early-ripening potato of the Zhukovsky cultivar grown on grey forest soils in a greenhouse. Low concentrations of Energia-M of 10, 50 mg/l did not influence the growth and growth activity significantly. Energia-M in a concentration of 80 mg/l increased the growth activity of the potato plants considerably. One of the objectives of the research was to study the antioxidant properties of the growth regulator Energia-M for Solánum tuberósum plants. Treatment of Solánum tuberósum with low concentrations of the organosilicon growth regulator Energia-M had little effect on the catalase activity in leaves and tubers, peroxidase activity decreased. When treating the Solánum tuberósum plants with a high concentration of the growth regulator Energy-M, 80 mg/l, the activity of catalase and peroxidase increased by 1.21 times. This pattern indicates the stimulation of metabolic processes in Solánum tuberósum plants grown on the grey forest soils of the Orel region with the application of the Energia-M growth regulator

Fungicidal activity of slow-release P(3HB)/TEB formulations in wheat plant communities infected by Fusarium moniliforme

Fungicidal activity of experimental tebuconazole (TEB) formulations was investigated in laboratory soil ecosystems in wheat plant communities infected by Fusarium moniliforme. TEB was embedded in the matrix of poly-3-hydroxybutyrate, shaped as films and microgranules. These formulations were buried in the soil with wheat plants, and their efficacy was compared with that of commercial formulation Raxil and with the effect of pre-sowing treatment of seeds. In the experiment with the initially infected seeds and a relatively low level of natural soil infection caused by Fusarium fungi, the effects of the experimental P(3HB)/TEB formulations and Raxil were comparable. However, when the level of soil infection was increased by adding F. moniliforme spores, P(3HB)/TEB granules and films reduced the total counts of fungi and the abundance of F. moniliforme more effectively than Raxil. Seed treatment or soil treatment with Raxil solution showed an increase in the percentage of rotdamaged roots in the later stages of the experiment. In the early stage (between days 10 and 20), the percentage of rotdamaged roots in the soil with TEB embedded in the slowly degraded P(3HB) matrix was similar to that in the soil with Raxil. However, the efficacy of P(3HB)/TEB formulations lasted longer, and in later stages (between days 20 and 30), the percentage of rot-damaged roots in that group did not grow. In experiments with different TEB formulations and, hence, different fungicidal activities, the increase in plant biomass was 15–17 to 40–60% higher than in the groups where TEB was applied by using conventional techniques

Microbiological Degradation of Poly(3-Hydroxybutyrate) Films in Different Edaphoclimatic Zones of Siberia

Проблема обращения с пластиковыми отходами ежегодно обостряется и требует комплексного подхода к ее решению. Замена синтетических материалов, полученных из ископаемого топлива, на углеродно-нейтральные биополимеры позволит уменьшить объем стойких к биоразложению отходов, снизить выбросы CO2 и количество п отребляемой э нергии. Однако темпы биодеградации изделий из биополимеров в окружающей среде зависят от многих факторов, поэтому в природных условиях даже полностью биоразлагаемые материалы могут сохраняться длительное время. В работе проведена оценка влияния почвенно-климатических и микробиологических характеристик на темпы биодеградации пленок из биополимера поли(3- гидроксибутирата) [П(3ГБ)] при экспозиции в сибирских почвах: дерново-карбонатной, криогенной и агрогенно-преобразованной. Анализ, проведенный методом главных компонент, показал, что в почвах разного типа, характеризующихся определенной температурой, увлажненностью, значениями рН, биогенностью и обилием микроорганизмов, скорость убыли массы пленок из П(3ГБ) в первую очередь определялась соотношением температуры и количества осадков и увеличивалась при повышении содержания гумуса в почве. Максимальные темпы убыли массы пленок – 0,63±0,09 и 0,93±0,013 мг∙сут‑1 – были з арегистрированы в агрогенных п очвах. Показано отсутствие корреляции убыли массы пленок с общей численностью микроорганизмов. Филогенетический анализ выявил отличия в наборе первичных деструкторов в разных типах почвThe urgency of handling plastic waste is escalating every year and the problem can be only solved using an integrated approach. Replacing non-degradable materials synthesised from fossil fuels with carbon-neutral biopolymers can reduce non-biodegradable waste, CO2 emissions and energy use. However, even completely biodegradable biopolymer materials will stay in the environment for a long time since the rate of their biodegradation depends on many factors. The paper evaluates the influence of edaphoclimatic and microbiological factors on the biodegradation rate of biopolymer films from the poly(3-hydroxybutyrate) [P(3HB)] when exposed to soddy-carbonate, cryogenic, and agrogenically transformed Siberian soils. A principal component analysis showed that in different soils, characterised by specific temperature, moisture content, pH values, biogenicity and abundance of microorganisms, the kinetics of mass loss of P(3HB)-films were primarily determined by the temperature- precipitation ratio and it increased as the content of humus in soil increased. The maximum rates of film mass loss of 0.63 ± 0.09 and 0.93 ± 0.01 mg ∙ day-1 were detected in agrogenic soils. No correlation between mass loss of the films and the total number of microorganisms was found. A phylogenetic analysis revealed differences in the composition of primary P(3HB)-degrading microorganisms in different soil type
