| 摘 要： | 以活性污泥作为菌种来源,采用常规微生物学方法分离到157株菌株,初筛后有21株菌株有絮凝活性,经复筛后有1株菌株C12絮凝活性最高.经与聚铝(PAC)和聚丙烯酰胺(PAM)比较,该菌株所产微生物絮凝剂沉降速度快,絮凝率高,显示了该微生物絮凝剂良好的实际应用前景.对其生长曲线的研究表明,C12菌株的絮凝活性与菌体生物量呈正相关性,且培养24h即可达到最高絮凝活性.

| Abstract: | 157 strains were separated from activited sludge with normal microbiological methode.By means of primary screening,21 bioflocculant producing strains were obtained.And a strain C12 was obtained with the highest flocculant activity after double screening.Compared with PAC and PAM,the bioflocclant has higher speed and better flocculant effect,implying the broad applicating prospect.The study of the growth curve showed that the growth of the strain was positive correlated to the flocculating activity at differ... |
