Halophilic microorganisms attract the attention of researchers due to their ability, acquired during adaptation to existence in extreme conditions, to synthesize biopolymers with unique properties that are potentially in demand in biotechnology. Bacteria inhabiting the rhizosphere of plants growing in soils with an increased level of mineralization often demonstrate growth-stimulating activity. The aim of the study was to analyze the taxonomic diversity of rhizosphere bacteria of the predominant halophytes of the coastal strip of the salty endorheic sedimentary lake Elton (Volgograd region). Enrichment cultures of microorganisms were obtained from rhizosphere samples of plants of the Chenopodiaceae family, with subsequent isolation of bacterial DNA, amplifi cation and sequencing of nucleotide sequences of variable fragments V3-V4 of the 16S ribosomal RNA gene. The analysis of the rhizosphere microbiome of Climacoptera lachnophylla (Iljin) Botsch., Salsola soda L., Anabasis salsa (C. A. Mey.) Benth. ex Volkens demonstrated a higher species diversity compared to the microbiomes of the soil and salt samples from the lake’s coastal zone. The dominance of the Proteobacteria and Firmicutes phyla was noted in all analyzed samples with diff erent ratios of their representatives. The rhizosphere microbiota of the studied plants was represented mainly by known species of the Halomonadaceae and Bacillaceae families, which, according to literature data, quite often have the ability to produce such metabolites regulating plant development as indole-3-acetic acid and siderophores.
