We have studied the taxonomic diversity of the microbial community of microbial mats and bottom sediments of the Garga hot spring using analysis of 16S rRNA gene amplicons. In the studied samples of microbial mats, Pseudomonadota, Cyanobacteriota, Ignavibacteriota, Chloroflexota, and Deinococcota have been identified. With a decrease in temperature, the proportion of representatives of Bacillota and Actinomycetota increases. In the microbial community of bottom sediments in all the studied thermal zones, representatives of the phyla Pseudomonadota and Bacteroidota dominate, Bacillota are codominants in bottom sediments. The study made it possible to establish the taxonomic composition and ratio of the main groups of microorganisms in the microbial communities of microbial mats and bottom sediments of the Garga hot spring.
