- Аннотация: The structure and specific characteristics of the hydrolytic microbial complexes from chestnut paleosols buried under the barrows of different ages (~4500 and ~3500 years) was compared with their modern analogue in microcosm experiments. Potential activity of the hydrolytic complex of the microbial community of the barrow paleosols was found to be higher than in the modern soil complex. The share of metabolically active cells revealed by FISH after the introduction of a growth-stimulating polysaccharide into the paleosol microcosm was 50% of the whole prokaryotic cell number. The paleosol community exhibited a more pro- nounced response to addition of the substrate than the modern soil community. The differences in the phyloge- netic taxonomic structure of the prokaryotic metabolically active hydrolytic complex in the buried and modern soils were revealed. The hydrolytic complex of modern soil was more diverse, while the dominant hydrolytic organisms revealed in paleosols were unicellular and mycelial Actinobacteria, as well as Proteobacteria. Keywords: paleosols, modern chestnut soil, hydrolytic microbial complex, FISH, number of active cells, phy- logenetic structure
