In the aerobic condition, the structure of crude oils were changed by hydrocarbon-oxidizing bacteria. The structure of crude oils was also changed by sulphate-reducing bacteria in the anaerobic condition. Sulphat e-reducing bacteria can make use of crude oils as sole carbon source. After tre atment of crude oils, the sample was analyzed with gas chromatograph(GC).The res ult of GC show the lighter compounds of crude oils decrease, but the more high w eight compounds increase. The sulfate-reducing bacteria were detected in the oi lfield water of Tarim basin. Its numbers were up to 104 cells/ml. The resu lts support the view that H2S is the origin of biology.
