一株絮凝剂高产菌的筛选及应用

摘要

采用平板划线分离法从污水中分离、纯化得到1株新型高效微生物絮凝剂产生菌N-7.从形态和生理生化特征来看,N-7菌可能是一种新型菌,属于氨醇杆菌属(Sphingobacterium),暂命名为Sphingobacterium sp.N-7.将N-7菌株与浓度为0.1mol/L的CaCl2溶液按一定比例投入到7种污水中,对4种污水有明显的絮凝效果.实验结果表明,此菌对煤矿污水的作用效果尤为明显.%A new kind of highly efficient microorganism flocculants-producing bacteria N-7 has been isolated and purified from wastewater by plate streak method.N-7 is preliminary identified as a new kind of bacteria based on its morphological and physiological characteristics,belonging to Sphingobacterium,tentatively named Sphingobacterium sp.N-7.When N-7 bacteria is put in 7 kinds of wastewater with CaC12 whose concentration was 0.1 mol/L by different proportions,the flocculation effect is obvious in four kinds of wastewater.The experimental results show that the effect is especially obvious on wastewater from coal mines.
