从造纸厂总排污口附近污泥中筛选出优良的纤维素降解菌 n- 7、n- 15、n- 16 ,选择 n- 7分离出三株较好的纤维素降解纯菌株 ,取代号为 w- 1、w- 2、w- 3,对各菌株降解纤维素的效果进行了分析比较 ,并对菌株间的相互作用进行了研究 ,发现不同纤维素降解菌的降解能力相差较远 ,各纤维素降解菌之间存在着协同和拮抗作用 Fine cellulose-degrading bacteria, n-7, n-15 and n-16, were screened from the sludge near the general sewage outfall of the paper mill, and three strains of better cellulose-degrading strains were isolated by selecting n-7. w-1, w-2, w-3, the degradation of cellulose strains of each strain were analyzed and compared, and the interaction between the strains were studied and found that different cellulose degrading bacteria degradation ability far, each There is synergy and antagonism between cellulose-degrading bacteria
