[Construction and function of a high-efficient complex microbial system to degrade cellulose and lindane in compost].
A complex microbial system capable of degrading cellulose and lindane with high efficiency was isolated from four compost heaps. It was selected and domesticated through two methods and by combination of different microbial communities. The results show that the complex microbial system can decompose filter paper, absorbent cotton, rice straw powder and sawdust effectively, especially has high degrading activity for the materials with higher native cellulose such as filter paper and absorbent cotton. As for both of them, the CMC saccharification activity is more than 40U and the degradation efficiency is more than 95% on the 5th day of inoculation. The complex microbial system can also keep a higher degrading capability in a wider range of pH. Filter paper and lindane can be degraded effectively by the complex microbial system during pH 7.0 - 9.0, and the degradation rates are more than 90 % and 45% respectively. Under pH 6.0 - 9.0, there is a good consistency between the degradation of Lindane and the decomposition of filter paper.
