SULFATE-REDUCING BACTERIA AND THEIR GEOBIOCHEMICAL ROLE OF SALT LAKE SEDIMENTS OF CHINA

Sulfate-reducing bacteria as a biogeochemical factor possess considerable functions for petroleum formation, secondary sulfide ore formation and gypsum ore destruction, soil alkalization and salification, and even for iron-steel corrosion. The bacteria also effect the kinds and growth of organiams in aquatic environments. Sulfate-reducing bacteria, therefore, are very important in economic fields. For many years, scientists have investigated their ecology, physiology and biochemistry etc. and accumulated considerable amount of data. This paper deals initially with sulfate-reducing bacteria from Dachaidan Salt Lake and Huining Saline Lake in China.
