SULFATE-REDUCING BACTERIA AND THEIR GEOBIOCHEMICAL ROLE OF SALT LAKE SEDIMENTS OF CHINA
-
摘要: 本文对我国某些盐湖和苦水湖沉积物中的硫酸盐还原细菌进行了分离和鉴定。讨论了它们所处的耐盐度、温度、pH等生态条件。从而探讨了它们对沉积物中有机质的富集和保存所起的作用。同时,由于它们在还原硫酸盐时产生大量的硫化氢,导致沉积物中的金属离子以硫化物形式大量地沉淀和富集,这对次生硫化矿沉积物的形成也起着较大的作用。Abstract: 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.
