| 摘 要： | 从活性污泥中筛选出一株高效的微生物絮凝剂产生菌, 鉴定为鲍曼不动杆菌。蚕豆根尖细胞微核试验未显示该菌株所产絮凝剂具有遗传毒性。该菌产絮凝剂的最佳碳源和氮源分别为葡萄糖和酵母浸出汁, 培养时间为24 h。在絮凝体系中加入Ca2+能明显提高发酵液的絮凝率。在pH为8.0时对高岭土悬浊液和污水具有良好的絮凝效果。

| Abstract: | An effective flocculant-producing microorganism was isolated from activated sludge which was identified as Acinetobacter baumannii. Its genetic toxicity is checked by the Vicia faba root-tip cells micronucleus test, the result has not demonstrated the genetic toxicity. The best carbon sources and nitrogen sources for flocculant production are glucose and yeast extract, the cultivation time is 24 hours. Addition of Ca2+ could obviously increase the flocculating rate. It has good flocculating effect on Kaolin suspension and sewage with pH at the scale of 8.0. |
