| 摘 要： | 从土壤中分离得到一株好氧反硝化细菌CY1, 该菌株在厌氧和好氧条件下均具有反硝化能力。硝酸盐氮初始浓度为137.25 mg/L, 30 h内硝酸盐氮去除率分别为99.98%(厌氧)和60.16%(好氧)。通过形态学特征、生理生化特性及16S rDNA同源性比较对菌株CY1进行鉴定, 初步判断CY1为泛养副球菌(Paracoccus pantotrophus)。

| Abstract: | An aerobic denitrifying bacterial strain CY1 was isolated from soil. The denitrifying experiment results showed that under anaerobic or aerobic conditions the reduction efficiency within 30 hours was up to 99.98% (anaerobic) and 60.16% (anaerobic) respectively with initial NO3-N concentration of 137.25 mg/L. According to its morphologica, physiological and biochemical characters, as well as 16S rDNA sequence homology comparison, strain CY1 was identified as a member of Paracoccus pantotrophus. |
