Using the 16S rRNA gene sequencing method we studied the diver-sity of the microbial community in different biotopes of Alla hot spring. In the communities of water, microbial material, and sediment, we revealed phylotypes belonging to 17 phyla of the Bacteria domain and one type of the Archaea domain. The species richness and diversity of the microbial community was higher in microbial material and bottom sediments than in water. A specific feature of the taxonomic composition of bottom sediments is the presence of Crenarchaeota type archaea.The research revealed the influence of temperature on the taxonomic composition of the microbial community.
