%X 采用YG培养基，结合蓝白斑筛选、异染粒染色及好氧除磷能力检测等实验，从城市生活污水处理厂好氧生化池的活性污泥中分离出7株好氧除磷菌；再经硝酸盐还原产气和缺氧培养实验，筛选出1株高效脱氮除磷菌；通过16S rRNA基因同源性比较和生理生化鉴定，初步将其鉴定为Pseudomonas grimontii，命名为C18.菌株C18在好氧培养24 h后，培养基中上清液磷浓度从38.7 mg/L降低到2.28 mg/L，除磷率达94.1%. C18在缺氧培养24 h后，培养基中上清液磷浓度从44.5 mg/L降低到5.21 mg/L，除磷率达88.3%；上清液硝酸盐氮浓度从184.2 mg/L降低到30.6 mg/L，脱氮率达83.4%.菌株C18最适脱氮除磷温度为30℃；最适脱氮除磷pH为7.5.
