| 摘 要： | 用常规的分离、纯化方法 ,从活性污泥中共分离出 32株菌株。将单菌株分别培养于“JM- 1”、“DF-1”、“PT- 1”液体培养基中 ,摇床培养一定时间后 ,以高岭土悬浊液筛选具有絮凝活性的菌种 ,由此获得 8株微生物絮凝剂产生菌 ,其中有 1株絮凝活性较高 ,初步鉴定为酵母菌 ,代号为“Dfjm- 1”,产生的絮凝剂命名为“Dtjm-1”。本文研究了“Dfjm- 1”在不同培养时间的生长情况、培养液中 p H值变化情况及絮凝活性变化情况 ,得出絮凝活性与菌生长量呈正相关关系 ,絮凝剂“Dtjm - 1”在菌生长稳定后期达到稳定活性的最高值

| Abstract: | strains were isolated from activated sludge with conventional methods Each strains was cultured in three different kinds of flocculant producing liquid mediums:JM 1,DF 1,PT 1 Kaolinite suspension was flocculated by the fermentation liquor which was regarded as the index to determine flocculating activity and ability to produce flocculant 8 flocculant producing strains were obtained Among them,a strain saccharomycete Dfjm 1 with high flocculating activity was obtained The microbial flocculant of Dfjm 1 produce is named Dtjm 1 In this paper,time course of flocculants production including growth,flocculating activity,and pH were studied |
