The degrading capability of a high-efficient complex microbial system to degrade cellulose and lindane was tested under different cultivating conditions. 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. The more cellulose was decomposed, the more lindane was degraded.

该论文作者对一组高效降解纤维素林丹的复合微生物菌系在不同培养条件下的降解能力进行了研究，结果表明，该复合菌系对滤纸、脱脂棉、稻秸粉和锯末等不同纤维素材料均有较强的降解能力，但相比之下对天然纤维素含量高的碳源降解效果更好。
