| 摘 要： | 采用稀释法和划线纯培养法,从土壤、湖水及湖底淤泥样品中培养分离出16株细菌,筛选获得2株高效微生物絮凝剂的生产菌株,利用其发酵液进行絮凝实验并进行菌种鉴定。结果表明,两株高效生产微生物絮凝剂的絮凝率均达到90%以上,两菌株初步鉴定为氮单胞菌(Azomonas sp.)和动胶菌属(Zoogloea ramigera)。

| Abstract: | Sixteen strains are isolated from the samples of soil, sewage and sludge of a lake using the pure culture law and the dilution. It is found that two out of 16 strains are high effective in producing flocculants. The fermentation solutions of these two strains are tested, and their flocculation rates reach 90% upward. These two stains are identified as Azomonas sp.and Zoogloea ramigera. |
