| 摘 要： | 利用PCR-DGGE(变性梯度凝胶电泳)技术对北京7个城市污水厂中10个处理系统的氨氧化细菌(AOB)种群结构进行了调查研究,发现城市污水厂的AOB种群多样性不高,除了硝化效果不好的一个污水厂外,其他9个污水处理系统中均检测到AOB的存在.切胶测序结果表明主要属于Nitrosomomu oligotropha/aestuarii-like cluster. |

| Abstract: | PCR-DGGE was applied to investigate the community structures of Ammonia-oxidizing Bacteria(AOB) in ten treatment systems of seven different Municipal Wastewater Treatment Plants(MWTPs) in Beijing.The results indicated that in these MWTPs,except for one system which had poor nitrification performance,all of the systems had AOB.But the diversity of AOB was low,and the AOB phenotypes were mainly grouped into the Nitrosomonas oligotropha/aestuarii-like cluster. |
