Main MicrobeGroup in the Shihongtan Uranium Deposit in Xinjiang and Their Metallogenic Significance

Key words: 
• Shihong tan uranium deposit /
• microbe, sulfate-reducing bacteria /
• isolation and identification /
• biomineralization /

Abstract: By using biological method, microorganisms in the Shihong tan u ranium deposit were iso lated and identified for the first time at home. Results showed that the distribution of themainm icrobe groups changed w ith the level of oxidation of the rock samples. A great deal of ae robic and anae robic bacteriaw ere ve ry active in the in termediate zone of oxidation and reduction, while in the o re zone, the speciesw asmonotonous, mainly anaerobic sulfate-reducing bacteria.In addition, the func tion ofm icroorgan isms during the formation of uranium deposit and the effect on the meta llogenic env ironment were also discussed.
