Taxonomic Structure of Bacterial Communities of Rhizospheric Soil under Bogs’ Plants

Abstract

For the first time, the ratio of large taxa and the genera spectrum of the prokaryotic community of the rhizosphere soil under typical plants of bogs were studied using high-throughput sequencing. The predominance of Acidobacteria and Alpha-proteobacteria and a low proportion of other taxa (less than 10%) were established. Representatives of the phyla Acidobacteria and Actinobacteria, as well as the class Alpha-proteobacteria class predominated among the 24 bacterial genera found. Common bacterial genera were identified in rhizospheric soil under plants and surface layers of peat. Representatives of most of these bacteria are adapted to grow in an acidic environment at low temperatures and consume various sugars, polysaccharides, aromatic compounds, and organic and amino acids. Bacteria of the genera Cytophaga and Acidothermus, widely distributed in bacterial communities, are capable of cellulose destruction, while representatives of the genus Occallatibacter utilize chitin and bacteria of the genus Nocardia consume humic substances and lignin.
