Abstract:
strain 49 #(BD-4),which had the highest flocculating activity among 752 strains,was picked out.The fermentation condi tions and the flocculating influence factors were studied.By testing,this cult ure broth had a much more ability to get rid of suspended materials in water and to decolourize the high-density dyestuff wastewater. In laboratory scale,bioflocculant was roughly extracted from culture broth by t he technological process,water extraction-organic solvent sediment-vacuum dry .The suitable work conditions of each step were set up through the tests.0 198 5g dry product was obtained from 100mL culture broth.
