| 摘 要： | 从活性污泥中分离筛选到一株产絮凝剂的细菌A25,鉴定为巨大芽孢杆菌Bacillus megaterium。该菌株产絮凝剂的最适碳源为麦芽糖,最适氮源为酵母提取物,最适pH为7.－10.0。絮凝剂的形成与菌体生长同步,均在10h达到最高值,该絮凝剂主要分布在发酵液中,另外还有一部分存在于菌体上,所产絮凝剂对供试的各种悬浮液和菌悬液都具有良好的絮凝效果。

| Abstract: | Abacterial strain A25, isolated from activated sludge and identified as Bacillius megaterium, could produce flocculant, The optimum carbon and nitrogen sources are maltose and yeast extract, respectively. The optimum pH range is 7.0～10.0. The flocculant was synthesized during the cell growth. The flocculant mainly exists in the supermatant. The partial purified flocculant could be kept in 60C for 1 hour without losing activity. |
