Under study was the microbiome structure in virgin light-colored hydromorphized solonetz soil by using molecular-genetic (analysis of prokaryotic metagenome) and cultural methods. It is shown that the prokaryotic diversity (according to OTU amount, Shennon index and Chao1) is gradually decreasing downwards the soil profile. Common features of microbiomes are found to be in the solonetz horizon and the lower part of the profile (low biodiversity, some Proteobacteria are dominant). A higher share (almost 20% of the community) of Archaea from the group of Thaumarchaeota is observed in the horizon overlying the solonetz one.
Keywords: solonetz soil, metagenome, soil microorganisms, pyrosequencing, 16S рРНК, Archaea, biodiversity.
