| 摘 要： | 从活性污泥中筛选得到了1株产絮凝剂的细菌菌株X-1,经细菌生理生化试验和16S rDNA基因序列分析初步鉴定为苍白杆菌属(Ochrobactrum sp.).菌株X-1的主要代谢产物通过蛋白质、糖类物质的定性分析初步定性为多糖类化合物.该菌的发酵液对印染污泥和印染废水均具有较好的絮凝处理效果. |

| Abstract: | Strain X-1 which can produce flocculants was isolated and purified from the active sludge.The results of morphology,physiological and biochemical properties of bacteria and 16S rDNA gene sequence analysis demonstrated that X-1 was closely related to the genus Ochrobactrum sp. The main metabolic products of strain X-1 were preliminary identified as polysaccharide compounds through the qualitative analysis of protein and carbohydrate.The bacteria fermentation liquid had good flocculantion effects on dyeing an... |
