Abstract

The results of studies of the effect of technogenic salinization on bacterial communities of rhizosphere plants of meadow grass (Poa pratensis L.), growing on the territory of the industrial development area of the Verkhnekamsk salt deposit (Solikamsk, Perm Region). The following changes were observed in the rhizosphere communities of bacteria: a decrease in the number and an increase in the taxonomic diversity of heterotrophic bacteria; decrease in the proportion of bacteria - representatives of the Gammaproteobacteria class; an increase in the proportion of bacteria belonging to the classes Actinobacteria (sites 2, 3), Alphaproteobacteria (sites 4, 5), Flavobacteria (site 3), Bacilli (sites 4, 5); change in the taxonomic composition of the bacterial community. Halophilic bacteria of the family Halomonadaceae (sites 2, 3 and 5) and of the genus Pseudomonas (site 4) dominated the sites with saline soil in the rhizosphere, indicating a possible symbiotic relationship between these bacteria and plants under saline conditions.
