Аннотация: Antimicrobial and antifungal properties of silver nanoparticles, silver ions, acrylate paint and cotton fabric impregnated with Ag nanoparticles were assessed against Escherichia coli (Gram-negative bacterium); Staphylococcus aureus and Bacillus subtilis (Gram-positive bacteria); Aspergillus niger, Aureobasidium pullulans and Penicillium phoeniceum (cosmopolitan saprotrophic fungi). The silver ions used in the bacterial susceptibility tests were released from pure silver electrodes using a 12 V battery-operated direct current generator. The water-based silver colloidal solution was obtained by electroreduction of silver ions in water. Nanosilver was less effective against E. coli, S. aureus, B. subtilis and P. phoeniceum compared to silver ions. However silver nanoparticles have prolonged bactericidal effect as a result of continuous release of Ag ions in sufficient concentration and thus nanoparticles can be more suitable in some bactericidal applications. The synthesized silver nanoparticles added to water paints or cotton fabrics have demonstrated a pronounced antibacterial and antifungal effect. В© 2011 Springer Science+Business Media B.V.

Аннотация: The present study investigates, for the first time, the structure of the microbial community of cryogenic soils in the subarctic region of Siberia and the ability of the soil microbial community to metabolize degradable microbial bioplastic – poly-3-hydroxybutyrate [P(3HB)]. When the soil thawed, with the soil temperature between 5-7 and 9–11 °C, the total biomass of microorganisms at a 10-20-cm depth was 226–234 mg g?1 soil and CO2 production was 20–46 mg g?1 day?1. The total abundance of microscopic fungi varied between (7.4 ± 2.3) ? 103 and (18.3 ± 2.2) ? 103 CFU/g soil depending on temperature; the abundance of bacteria was several orders of magnitude greater: (1.6 ± 0.1) ? 106 CFU g?1 soil. The microbial community in the biofilm formed on the surface of P(3HB) films differed from the background soil in concentrations and composition of microorganisms. The activity of microorganisms caused changes in the surface microstructure of polymer films, a decrease in molecular weight, and an increase in the degree of crystallinity of P(3HB), indicating polymer biodegradation due to metabolic activity of microorganisms. The clear-zone technique – plating of isolates on the mineral agar with polymer as sole carbon source – was used to identify P(3HB)-degrading microorganisms inhabiting cryogenic soil in Evenkia. Analysis of nucleotide sequences of rRNA genes was performed to identify the following P(3HB)-degrading species: Bacillus pumilus, Paraburkholderia sp., Pseudomonas sp., Rhodococcus sp., Stenotrophomonas rhizophila, Streptomyces prunicolor, and Variovorax paradoxus bacteria and the Penicillium thomii, P. arenicola, P. lanosum, Aspergillus fumigatus, and A. niger fungi. © 2020 Elsevier Ltd

Аннотация: Cation exchange resins are widely used for water softening and demineralization all over the world. Deposition, metabolism, and growth of bacteria and fungi on the resin beads cause capacity and performance losses, especially during repeated use in cyclic and long-term operations. Over the last decades, modification of different materials by silver nanoparticles (AgNPs) has demonstrated to present significant opportunities in mitigating biofouling problems. The paper deals with a novel facile technique of introducing silver colloids (AgC) into cation exchange resin, providing the formation of silver micro-and nano-inclusions on the cation resin beads. The scanning electron microscope (SEM) measurements have confirmed a spherical shape and uniform distribution of AgC (50 - 1000 nm) on the surface of the resin. To evaluate the antibacterial and fungicidal properties of AgC on the cation resin beads, we have used Aureobasidium sp., Penicillium sp., and Staphylococcus aureus cultures. AgC coating has proved to efficiently prevent bacteria/biofilm growth on the cation resin beads and thereby significantly increase the service life of the cation exchange resin, especially in hot climatic conditions. Possible antibiofouling mechanisms of the modified nanocomposite cationite have been discussed. Since 2020, the modified silver-containing cationite has been successfully utilized for water softening systems of boiler equipment in Uzbekistan, demonstrating the suitability of the suggested facile coating technique for reducing fouling of cation-exchange resin.

ПОДЗОЛИСТЫЕ ПОЧВЫ (RETISOLS) -- СТАРОВОЗРАСТНЫЕ ЕЛЬНИКИ -- МИКРОБИОМЫ -- ПИРОГЕННЫЕ И НЕПИРОГЕННЫЕ ГОРИЗОНТЫ -- БИОРАЗНООБРАЗИЕ ПРОКАРИОТ И ГРИБОВ
Аннотация: Представлены данные по микробиологическим свойствам подзолистых почв (Retisols) старовозрастных еловых лесов на территории средней тайги Красноярского края и Республики Коми. Несмотря на различное географическое положение, почвы этих регионов характеризуются близкими морфологическими и физико-химическими свойствами. В почвах ельников Республики Коми и Красноярского края не обнаружено достоверной разницы в накоплении микробной биомассы и скорости микробного дыхания. Однако содержание в почвах углерода и азота, а также микробной биомассы оказывало значимое влияние на качественный состав микробиомов пирогенных и непирогенных горизонтов почв. Отмечено существенное влияние пирогенного фактора на α-разнообразие бактерий и грибов. Показано, что при освоении органического вещества с наличием пирогенного углерода активно участвуют представители доминантных фил бактерий (Proteobacteria, Actinobacteria и Planctomycetes) и грибов (Ascomycota, Basidiomycota и Mucoromycota). В состав микробиомов верхних пирогенных подгоризонтов входят группы карботрофных бактерий (Thermomonosporaceae, Isosphaeraceae, Bacillaceae, Xanthobacteraceae) и грибов из классов Dothideomycetes (р. Cenococcum), E-urotiomycetes (р. Penicillium), Sordariomycetes (р. Trichoderma), Leotiomycetes (р. Oidiodendron), Umbelopsidomycetes (р. Umbelopsis), которые способны к преобразованию продуктов пиролиза в доступные и нетоксичные субстраты для других организмов
Data on the microbiological properties of podzolic soils (Retisols) of old-growth spruce forests in the middle taiga of the Krasnoyarsk Krai and the Komi Republic are presented. It is shown that, despite the geographical distance, the soils of the regions are characterized by similar morphological and physicochemical properties. It was noted that in the soils of the spruce forests of the European North (R. Komi) and middle Siberia (Krasnoyarsk Krai), no significant difference in the accumulation of microbial biomass and the rate of microbial respiration was found. However, the content of carbon and nitrogen in soils, as well as microbial biomass, had significant differences in the qualitative composition of microbiomes in pyrogenic and non-pyrogenic soil horizons. A significant effect of the pyrogenic factor on the α-diversity of bacteria and fungi was noted. It was shown that representatives of the dominant phyla of bacteria (Proteobacteria, Actinobacteria and Planctomycetes) and fungi (Ascomycota, Basidiomycota and Mucoromycota) actively participate in the assimilation of organic matter with the presence of pyrogenic carbon. The microbiomes of the upper pyrogenic subhorizons include groups of carbotrophic bacteria (Thermomonosporaceae, Isosphaeraceae, Bacillaceae, Xanthobacteraceae) and fungi from the classes Dothideomycetes (Cenococcum), Eurotiomycetes (Penicillium), Sordariomycetes (Trichoderma), Leotiomycetes (Oidiodendron), Umbelopsidomycetes (Umbelopsis), which are capable of converting pyrolysis products into accessible and non-toxic substrates for other organisms

ПОДЗОЛИСТЫЕ ПОЧВЫ (RETISOLS) -- СТАРОВОЗРАСТНЫЕ ЕЛЬНИКИ -- МИКРОБИОМЫ -- ПИРОГЕННЫЕ И НЕПИРОГЕННЫЕ ГОРИЗОНТЫ -- БИОРАЗНООБРАЗИЕ ПРОКАРИОТ И ГРИБОВ
Аннотация: Представлены данные по микробиологическим свойствам подзолистых почв (Retisols) старовозрастных еловых лесов на территории средней тайги Красноярского края и Республики Коми. Несмотря на различное географическое положение, почвы этих регионов характеризуются близкими морфологическими и физико-химическими свойствами. В почвах ельников Республики Коми и Красноярского края не обнаружено достоверной разницы в накоплении микробной биомассы и скорости микробного дыхания. Однако содержание в почвах углерода и азота, а также микробной биомассы оказывало значимое влияние на качественный состав микробиомов пирогенных и непирогенных горизонтов почв. Отмечено существенное влияние пирогенного фактора на α-разнообразие бактерий и грибов. Показано, что при освоении органического вещества с наличием пирогенного углерода активно участвуют представители доминантных фил бактерий (Proteobacteria, Actinobacteria и Planctomycetes) и грибов (Ascomycota, Basidiomycota и Mucoromycota). В состав микробиомов верхних пирогенных подгоризонтов входят группы карботрофных бактерий (Thermomonosporaceae, Isosphaeraceae, Bacillaceae, Xanthobacteraceae) и грибов из классов Dothideomycetes (р. Cenococcum), E-urotiomycetes (р. Penicillium), Sordariomycetes (р. Trichoderma), Leotiomycetes (р. Oidiodendron), Umbelopsidomycetes (р. Umbelopsis), которые способны к преобразованию продуктов пиролиза в доступные и нетоксичные субстраты для других организмов
Data on the microbiological properties of podzolic soils (Retisols) of old-growth spruce forests in the middle taiga of the Krasnoyarsk Krai and the Komi Republic are presented. It is shown that, despite the geographical distance, the soils of the regions are characterized by similar morphological and physicochemical properties. It was noted that in the soils of the spruce forests of the European North (R. Komi) and middle Siberia (Krasnoyarsk Krai), no significant difference in the accumulation of microbial biomass and the rate of microbial respiration was found. However, the content of carbon and nitrogen in soils, as well as microbial biomass, had significant differences in the qualitative composition of microbiomes in pyrogenic and non-pyrogenic soil horizons. A significant effect of the pyrogenic factor on the α-diversity of bacteria and fungi was noted. It was shown that representatives of the dominant phyla of bacteria (Proteobacteria, Actinobacteria and Planctomycetes) and fungi (Ascomycota, Basidiomycota and Mucoromycota) actively participate in the assimilation of organic matter with the presence of pyrogenic carbon. The microbiomes of the upper pyrogenic subhorizons include groups of carbotrophic bacteria (Thermomonosporaceae, Isosphaeraceae, Bacillaceae, Xanthobacteraceae) and fungi from the classes Dothideomycetes (Cenococcum), Eurotiomycetes (Penicillium), Sordariomycetes (Trichoderma), Leotiomycetes (Oidiodendron), Umbelopsidomycetes (Umbelopsis), which are capable of converting pyrolysis products into accessible and non-toxic substrates for other organisms

ТЕМНО-СЕРАЯ ПОЧВА (HAPLIC GREYZEMS) -- РУБКИ -- ПОЖАР -- БИОУДОБРЕНИЕ -- ДЫХАТЕЛЬНАЯ И ФЕРМЕНТАТИВНАЯ АКТИВНОСТЬ, -- МИКРООРГАНИЗМЫ-КАРБОТРОФЫ -- БИОИНДИКАТОРЫ СОСТОЯНИЯ ПОЧВЫ
Аннотация: Биологическую активность темно-серой почвы исследовали в 100-летнем сосняке разнотравно-зеленомошном Погорельского бора Красноярской лесостепи. В 2017 г. в сосняке были проведены выборочные рубки, а в мае 2022 г. произошел сильный пожар. Для улучшения лесовосстановления и повышения биологической продуктивности почвы на вырубленные и горевшие участки вносили биоудобрение на основе опилочно-почвенного субстата с микопродуктом и мочевиной (ОПСМ + М). На экспериментальных участках (пасека, волок, фон) проводили ежегодный учет самосева сосны. Биоиндикацию состояния почвы оценивали на основании общей численности и соотношения долей эколого-трофических групп микроорганизмов, активности ферментов, содержания микробной биомассы, интенсивности базального дыхания и удельного дыхания микробной биомассы. Внесение биоудобрения на вырубленные участки способствовало подщелачиванию почвы на 0.2–0.4 ед., сохранению влажности, увеличению содержания азота (на 5–14%) и микробной биомассы (в 1.2–1.6 раза) по сравнению с контрольными вариантами. Воздействие биоудобрений на всхожесть и рост самосева сосны отмечено на второй год после внесения: на опытных участках самосева было в 4–6 раз больше, чем на контрольных. Поступление в почву обгоревших растительных остатков, углей и золы в первую неделю после пожара привело к активизации микроорганизмов-карботрофов, которые увеличивали общую численность микроорганизмов, микробную биомассу, активность уреазы и инвертазы. Однако к концу вегетационного периода отмечали снижение микробиологической активности, что указывало на постпирогенную депрессию микробоценозов. Внесение биоудобрения на сгоревшую поверхность участков нивелировало влияние пирогенного воздействия и стимулировало образование всходов сосны обыкновенной, количество которых было достоверно больше, чем на контрольных участках. Установлено, что универсальными биоиндикаторами, адекватно отражающими состояние почвы после всех антропогенных воздействий, были микробная биомасса, удельное микробное дыхание, ферментативная активность и общая численность микроорганизмов. Специфической биоиндикацией состояния почвы после пожара являлось увеличение доли бактерий Serratia plymuthica, Bacillus mycoides и грибов родов Trichoderma, Penicillium и Mortierela.
3The biological activity of dark gray soil was studied in a 100-year-old pine forb-green-moss forest of the Pogorelsky pine forest of the Krasnoyarsk forest-steppe. In 2017, selective cuttings were carried out in the pine forest, and in May 2022 there was a strong fire. To improve reforestation and increase the biological productivity of the soil, bio-fertilizer based on sawdust-soil substrate with the addition of urea and mycoproduct (SSSU + M) was applied to cut and burned areas. On the experimental plots (Paseka, Volok, Fon), an annual count of self-seeding of pine was carried out. Bioindication of the soil condition was assessed based on the total number and ratio of ecological-trophic groups of microorganisms, enzyme activity, microbial biomass content, intensity of basal respiration and specific respiration of microbial biomass. The application of biofertilizer to the cut areas alkalized the soil by 0.2–0.4 units, retained moisture, increased the content of nitrogen (by 5–14%) and microbial biomass (by 1.2–1.6 times), compared with the control options. The impact of biofertilizers on the germination and growth of self-seeding of pine was noted in the second year after application – in the experimental plots of self-seeding it was 4–6 times greater than in the control ones. The entry of burnt plant residues, coals and ash into the soil in the first week after the fire led to an increase in some microbiological indicators, the activity of urease and invertase, and the activation of carbotrophic microorganisms. However, by the end of the growing season, a decrease in microbiological activity was noted, which indicated a post-pyrogenic depression of microbocenoses. The introduction of biofertilizer on the burnt surface of the plots leveled the effect of pyrogenic effects and stimulated the formation of shoots of scots pine, the number of which was significantly higher than in the control plots. It was found that the universal bioindicators that adequately reflect the state of the soil after all anthropogenic impacts were microbial biomass, specific microbial respiration, enzymatic activity and the total number of microorganisms. A specific bioindication of the soil condition after the fire was an increase in the proportion of bacteria Serratia plymuthica, Bacillus mycoides and fungi of the genera Trichoderma, Penicillium and Mortierela
