Biological flocculation agent as a safe non-toxic, flocculating activity is high, no secondary pollution of new flocculant, on human health and environmental protection has very important practical significance. However, the present study more in the laboratory stage. This topic is based on the purpose of increase production, the design group of type fermentation process for microbial flocculant development research. This study investigated the fermentation process of flocculating agent produce bacteria fermentation process of a series of parameters, including: the best of the inoculation quantity, growth curve, pH value, dissolved oxygen value, fermentation medium sugar concentration, fermentation medium flocculating rate and flocculating agent purification content production, etc. On the basis of a large number of experiments, it is concluded that the batch type fermentation of each parameter. At the same time in the best condition to get flocculating agent for extraction and purification, in the literature material and the basis of experiment, formulated the purification methods. Systematically summarized the microbial flocculant batch type fermentation and purification process for flocculating agent of industrial production and promotion use, so as to provide theoretical basis for the industrial production of the product as soon as possible.
