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.</p></abstract><trans-abstract xml:lang="ru"><p>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.</p></trans-abstract><kwd-group xml:lang="en"><kwd>подзолистые почвы (Retisols) старовозрастные ельники микробиомы пирогенные и непирогенные горизонты биоразнообразие прокариот и грибов</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>подзолистые почвы (Retisols) старовозрастные ельники микробиомы пирогенные и непирогенные горизонты биоразнообразие прокариот и грибов</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы благодарят к. б. н.
