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.

沼泽植物下根际土壤细菌群落的分类结构

摘要

利用高通量测序技术,首次研究了典型沼泽植物下根际土壤大分类单元的比例和属谱。确定了酸细菌和α-蛋白细菌的优势以及其他类群的比例很低(少于10%)。在发现的24个细菌属中,以酸性菌群和放线菌群为代表,并且以Alpha变形杆菌为代表。在植物和泥炭表层下的根际土壤中鉴定出常见细菌属。这些细菌中大多数的代表适合在低温下的酸性环境中生长,并消耗各种糖,多糖,芳香族化合物以及有机和氨基酸。食丝菌属细菌嗜酸乳杆菌和酸性嗜热菌广泛分布于细菌群落中,能够破坏纤维素,而Occallatibacter属的代表利用甲壳质,诺卡氏菌属的细菌则消耗腐殖质和木质素。
