Phylogenetic diversity of microbiota of sediments, water and coastal surface technogenic formations of soda sludge storage (Berezniki, Perm region, Russia)

摘要

The phylogenetic diversity of the microbial community was evaluated using metagenomic sequencing. The objects of the study were water, sediments and coastal surface technogenic formations of the soda sludge storage facility of the soda plant "Soda", Berezniki (Perm region, Russia). The bacterial communities of the all samples were dominated by representatives of two classes: Bacilli and Gammaproteobacteria. At the same time, differences in the species diversity of microbiocenoses were noted. The water samples with a pH of 12.6 were characterized of lowest biodiversity, where the basis of the microbial community was only 3 classes: Bacilli (57,51%), Gammaproteobacteria (29,79%) and Clostridia (4,55%). The most diverse microbial community (8 classes) was noted in the soda sediments;;the pH of these samples was 11.
