Acidobacteria in microbial communities of the bog and tundra lichens

Bacterial communities of the lichens from a Sphagnum bog (Karelia) and tundra (Vorkuta oblast) were investigated. Members of the phylum Acidobacteria were numerous in the thallus of living and decaying lichens (3.8 × 10 8 cells/g), constituting 6 to 32% of the total bacterial number. Pure cultures o...

Description
Summary:Bacterial communities of the lichens from a Sphagnum bog (Karelia) and tundra (Vorkuta oblast) were investigated. Members of the phylum Acidobacteria were numerous in the thallus of living and decaying lichens (3.8 × 10 8 cells/g), constituting 6 to 32% of the total bacterial number. Pure cultures of acidobacteria were isolated from the samples of living and decaying lichen thallus. Ten of them were identified and classified as members of subgroup 1 of the Acidobacteria . The hydrolytic activity of two strains isolated from the living and decomposing zones of the thallus was investigated. They were capable of growth on xylan, starch, pectin, laminarin, and lichen extract. Acidobacteria were shown to be a stable and numerous component of microbial communities of the bog and tundra lichens.
