752 strains were isolated and purified from soil or mud collected from natural and artificial environment. Through investigating the flocculating abilities for kaolin clay of culture broth, strain 49#(BD-4), which had the highest flocculating activity among them，was finally picked out. The fermentation conditions, extraction conditions and the flocculating influence factors were studied. The chemical properties and composition of the culture extractive were also analyzed.
