| 摘 要： | AK新型短程反硝化除磷脱氮工艺的反硝化除磷段活性污泥中分离到几株以亚硝酸盐为电子受体的反硝化除磷菌，并优选出代表菌株F10，通过菌落形态、生理生化特性、细胞培养特征以及16SrDNA序列同源性分析，鉴定为鞘氨醇杆菌属（Sphingobacterium）。通过间歇培养实验考察该菌的关键生长影响因子，表明亚硝酸盐浓度为15mg／L、pH值7．0左右、温度30℃的条件下该菌可以获得最佳生长。

| Abstract: | Some denitrificative dephosphorized bacteria which take the nitrite as the electronic acceptor have been separated from the active sludge stemmed out of the new short-range denitrificative dephosphorized technology,and then optimizes their representative strain.By analyzing the colony shape,physiological and chemical characteristics,and cell fostering,we make an appraisal as sphingobacteium.By investigating the important affective factors within the intermittent fostering experiment,we get that,its optimum ... |
