摘　　要：用常规的细菌分离纯化方法从土壤、河湖、活性污泥中分离出 75 2支菌株 ,以发酵液对高岭土悬浮液絮凝效果为指标 ,筛选出 1株絮凝剂产生高效菌 ,研究了该菌最佳生长条件 ;进行了实际废水试验 ,探讨了絮凝效果的影响因素 ;确定了提取工艺的操作条件 ,并对微生物絮凝剂粗提物的性质、组成进行了分析。752 strains were isolated and purified from soil or mud collected from natural and artificial environment. Through investigating the flocculating abilities for kaolin clay of culture broth, strain 49# (BD-4), which had the highest flocculating activity among them, was finally picked out. The fermentation conditions, extraction conditions and the flocculating influence factors were studied. The chemical properties and composition of the culture extractive were also analyzed.
