【Abstract】 Microbial flocculent produced by microbe is widely used to treat wastewater and separation process in industry. Compared with inorganic flocculent and organic macromolecular flocculent,microbial flocculent can be automatically decomposed. The recent research achievements of microbial flocculent are reviewed. The excellent bacillus for producing bioflocculant are mainly Bacillus and Pseudomonas . The media culturing and other culturing conditions are introduced. Meanwhile,the investigation methods for microbial flocculent are emphatically generalized. The present problems in the studies of microbial flocculent are pointed out and the future trends for developing microbial flocculent research are presented.更多还原
