Abstract
The present application provides a method for simultaneously synthesizing a biological flocculant with polysaccharide and γ-PGA as the active components by usingis inoculated to a slant culture medium to be cultured; a single colony on a fresh plate is inoculated to a seed culture medium to be cultured; and a seed fermentation broth is inoculated to a fermentation culture medium to be cultured, and then the biological flocculant having two different components is obtained. The flocculant synthesized in the present invention is high in activity and good in thermal stability; and especially, the flocculation effect of polysaccharide is relatively superior under acidic and neutral conditions, and the flocculation activity of γ-PGA is relatively higher under neutral and alkaline environments, which can satisfy a relatively large pH application range.
