In order to investigate the capability of degradation lindane and lignocellulose of a microbial community, the gas chromatography(GC) was used to determine the concentration of lindane. After 18 days cultured, lindane reduced 6.25% more than the control. And the result of gas chromatography and mass spectrometry (GCMS) showed that the species and quantum of fermentation productions changed much in different phase. In order to determine the bacterial composition of the community, clone library was used to clarified bacterial composition. Constructed 16S rDNA clone library showed 60% closest relative among them were known the detailed information. Strain of closest relative of Clostridium may be main contribute to lignocellulose degradation, and closest relative of Proteobacterium may be the main contribute to degradation organochlorine pesticide (lindane).
