In this study, the rhizosphere microbiome of black saxaul (Halophylon aphyllum) growing in the dried bed region of the Aral Sea was analyzed, and the adaptation of the isolated strains to stress conditions was investigated through isolates tolerant to different NaCl concentrations. Bacterial isolates tolerant to 5% NaCl were obtained. Among them, the isolates Qst 4/1, Qsi 1/3 (Bacillus firmus), Q.sak 10/1 (Staphylococcus succinus), Qst 1/4, and Qst 1/2 (Proteus mirabilis) demonstrated growth at 14% NaCl, indicating their significant role in supporting plant growth and various physiological processes under high salinity conditions.
