| Abstract: | A strain of microorganism named Aspergillus M-25 which produces flocculant was isolated from activated sludge.Through orthogonal test,the optimum cultural conditions were found to be Zapeke,primary pH 5.0,25 ℃ and 140 r/min.The strain produced a strong\|activating flocculant with flocculating rate of 97.15% against kaolin clay suspension. |
