Аннотация

In this study, we determined the concentration of chlorophyll a in biofilms formed on rocky substrates, in the surface water microlayer, water column, and near-bottom water layer of the coastal zone of Lake Baikal. High throughput sequencing of 16S rRNA and rbcL gene libraries revealed high genetic and taxonomic diversity of photoautotrophic microbial communities in the studied ecotopes of the lake. The UPGMA analysis indicated that the composition of photoautotrophic communities largely depends on both the geographical location and ecotope. Using electron microscopy, we described the structure and composition of biofilms.
