Аннотация:The active growth and development of psychrotolerant actinomycetes take place in peat and pod-
zolic soils of the tundra and taiga at temperatures below 10 C. The population density of psychrotolerant myce-
lial prokaryotes in these soils reaches thousands and tens of thousands of CFU/g of soil, and the length of their
mycelium is up to 380 m/g of soil. The application of fluorescent in situ hybridization (the FISH method) dem-
onstrated that the metabolically active psychrotolerant representatives of the phylogenetic group of Actinobac-
teria comprise up to 30% of the total number of bacteria in prokaryotic microbial communities of oligotrophic
peat bog and podzolic soils. The portion of metabolically active mycelial actinobacteria exceeds the portion of
unicellular actinobacteria. Psychrotolerant streptomycetes isolated from peat bog soils possess pectinolytic,
amylolytic, and antagonistic activities at low temperatures (5 C).
