“…Previous microbiogical studies based on culture-dependent methods recovered a large number of bacterial strains from thermal springs located in Baikal Rift zone. Isolates included alkaliphilic and alkalitolerant thermophilic bacteria (Zaitseva et al 2004;Kublanov et al 2009;Lavrentieva et al 2009;Namsaraev et al 2010;Rosanov et al 2014a;2014b), anoxygenic phototrophic bacteria (Kompantseva & Gorlenko, 1988;Gorlenko et al 2014;Gaisin et al, 2015;Nuyanzina-Boldareva et al, 2016). Our previous study focused on the microbial activities and included results of the determination of the microbial processes rates in microbial mats and sediments in some studied hot springs (Namsaraev et al 2003;Bryanskaya et al 2006;Zaitseva et al 2007) and microbial taxonomic diversity (Radnagurueva et al 2016;Lavrentieva et al 2018).…”
