Abstract:
A flocculant-producing bacterium from Cangshan soil named CS-26 was isolated. Through tests, the optimum culture conditions were found to be: starch 20 g,KH2PO4 2 g,polypeptone 1 g,MgSO4·7H2O 0.5 g,CaCl2 0.5 g,pH 7.0,H2O 1L,30 0C, 180 r/min, 72 h. The strain CS-26 could produce a strong-activiting flocculant with flocculating rate of 98.85 % against kaolin clay suspension.
Key words: bioflocculant, screening, flocculating activity, culture conditions
