摘 要: | 目的]为了筛选具有高絮凝活性的产生菌。方法]采用稀释涂布法、平板划线分离法筛选分离菌株,并且通过菌落形态观察、生理生化特性鉴定絮凝菌。结果]从样品中初筛得到17株具有絮凝性的菌株,经复筛后得到4株高效(絮凝率>85%)絮凝菌,其中TS-4絮凝活率为87.78%。TS-4为革兰氏阳性杆菌,属于芽孢杆菌科芽孢杆菌属。结论]分离出的TS-4菌可用于废水的生物处理,为生产生物絮凝剂奠定基础。

Abstract: | Objective] To screen strain with high flocculating activity.Method] The diluted coating method and the flat crossed separation method were adopted to screen strains,and the flocculation stain were identified through colony morphological observation,physiological and biochemical characteristics observation.Result] From the samples we screened seventeen flocculation strains,after rescreening the four efficient flocculation were got(flocculation rate> 85%),in which flocculation rate of TS-4 was 87.78%.TS-4 was Gram-positive bacteria,belonging to Bacillaceae Bacillus.Conclusion] TS-4 can be used for biological treatment of waste water,which laid the foundation for the production of bioflocculant. |
