ALKALIPHILIC ANAEROBIC COMMUNITY AT PH-10

Relict or ancient microbial communities in extreme environment might be analogous to the centers of origin of bacterial diversity. A bacterial community of an alkaline lake was investigated, and the diversity of bacteria found there indicates that both conditions of autonomy and phylogenetic variety are fulfilled for anaerobic bacteria developing at pH 10 +/- 0.2. Major functional groups in the trophic network were present. Representatives of proteolytic, bacteriolytic, cellulolytic, saccharolytic, dissipotrophic, acetogenic, sulfate-reducing, methanogenic bacteria were isolated.
