It is established that the microbial community of the bacteria-destructors in bottom sediments and crust of the soda Lake Khilganta is able to develop in a wide range of pH and mineralization. The community of bacteria-destructors functions most actively in neutral or weakly alkaline conditions and at low salt concentration. The simultaneous action of two factors-high pH and the salinity of medium-results in decrease of the number of cells and drop in the destroying activity of the community. The obtained data confirm the earlier proposed hypothesis that at high mineralization the destroying processes are inhibited, which leads to accumulation of organic matter.
