Bacterial communities structure of the main types of bog plants

Abstract

This research based on both direct and seeding methods revealed high bacteria concentration on bogs plants: Carex nigra, Eriophorum vaginatum, Drosera rotundifolia, Ledum palustre. There was identified a correlation between bacteria number and investigated plants’ organs. Proteobacteria dominated in phyllosphere, bacilli and actinomycetes - in rizoplane and rhizospheric soil. Representatives of the genus Pseudomonas and Erwinia dominated in phyllosphere. Nitrogenase activity of bacterial populations in rhizosphere soil was high and reached the maximum in Drosera rhizospheric soil.
