【Abstract】 flocculant producing strains have been selected from soil and activated sludge by means of the common bacteria screening and purification method.2 strains with higher turbidity removal ability are superior to others after reselection.Major factors affecting the flocculation are studied.The flocculating rate is measured after 30 minutes′ flocculation of the brewery yeast suspension solution,with flocculants being produced by the two strains.The distribution of flocculating activity in the culture broth and the optium flocculant producing conditions are studied.更多还原
