摘　　要：本研究以松花江附近树根土为试验材料,筛选出具有絮凝活性的微生物菌株16株,其中编号为S-2的菌株絮凝活性最高,达到76.8%。使用单因素与正交试验对其培养基碳源、氮源种类与浓度和pH进行优化,最优培养基组成为葡萄糖3.5%,蛋白胨0.2%,NaCl 0.5%,pH值7.5,在此条件下,絮凝剂产生菌S-2絮凝活性可达92.8%。In this study,16 microbial strains with flocculation activity were screened out by taking root soil near songhua river as the experimental material,among which the strain numbered s-2 had the highest flocculation activity,reaching 76.8%.The optimal medium composition was glucose 3.5%,peptone 0.2%,NaCl 0.5%,and pH value was 7.5.Under these conditions,the flocculant producing bacteria s-2 could achieve flocculation activity of 92.8%.
