摘　　要：从制药废水中筛选絮凝剂产生菌,得到一株对高岭土悬浊液具有较高絮凝活性的微生物絮凝菌H-6,根据菌株的生理生化鉴定初步确定该菌株曲霉,该菌的絮凝活性物质分布在发酵液上清液中,在45℃,pH为5.0时,能利用无机碳源和氮源且菌的生长量最大。In this paper,an efficient flocculant-producing strain H-6 was isolated from drugs manufacture waste water,which had a good flocculation effect on kaolin clay suspension.Based on morphological,physiological and biochemical characteristics analysis,strain H-6 was classified asaspergillus sp.And the flocculants were mostly concentrated in the supernatant.In 45℃,pH 5.0,H-6 can use inorganic carbon source and nitrogen source and bacteria growth is the largest.
