Microbial communities of the stratified soda Lake Doroninskoe (Transbaikal region)
Original language description
The physicochemical properties, species composition, and vertical distribution of microorganisms in the water column, shoreline microbial mat, and small shoreline mud volcanoes of the stratified soda Lake Doroninskoe were investigated in September 2007.The lake is located in the Transbaikal region, in the permafrost zone (51A degrees 25'N; 112A degrees 28'E). The maximal depth of the contemporary lake is about 6 m, the pH value of the water is 9.72, and the water mineralization in the near-bottom horizon is 32.3 g l(-1). In summer, the surface oxygen-containing horizon of the water column becomes demineralized to 26.5 g l(-1); at a depth of 3.5-4.0 m, an abrupt transition occurs to the aerobic zone containing hydrosulfide (up to 12.56 g l(-1)). Hydrosulfide was also detected in trace quantities in the upper water horizons. The density stratification of the water column usually ensures stable anaerobic conditions until the freezing period (November and December). The primary production
