| 摘 要： | 海洋生态系统氮素循环对维持海洋生态收支平衡具有重要意义,由厌氧氨氧化细菌(anaerobic ammonia-oxidizing bacteria,ANAMMOX Bacteria)推动的厌氧氨氧化过程是海洋氮素移除的重要途径.本研究采用荧光定量PCR(q PCR)技术,并结合环境理化因子,分析了2011年夏季长江口邻近海域沉积物中厌氧氨氧化细菌的种群丰度分布特征.结果表明,厌氧氨氧化细菌的种群丰度在长江口邻近海域的空间分布与环境因子密切相关,总有机碳含量、盐度、铵盐浓度对长江口邻近海域沉积物中厌氧氨氧化细菌的种群丰度具有重要调控作用.厌氧氨氧化细菌的丰度分布与总有机碳含量呈显著正相关关系(P0.01,r=0.69),同时又随亚硝酸盐浓度、溶解氧浓度的升高而降低,而盐度对厌氧氨氧化细菌丰度分布的影响较为复杂.

| Abstract: | Marine nitrogen cycle is of great significance to maintain the marine ecological balance. Anaerobic ammonia oxidation (ANAMMOX) process driven by anaerobic ammonia-oxidizing bacteria is an important way of promoting the marine nitrogen removal. In this study, quantitative PCR (qPCR), combining with environmental factors analysis, were used to study the distribution of ANAMMOX bacteria in the sediments from Yangtze River Estuary and its adjacent waters in summer, 2011. The results showed that the spatial abundance distribution of ANAMMOX bacteria was closely related to environmental factors. Total organic carbon, salinity, and concentration of ammonium played vital roles in regulating ANAMMOX bacteria abundances in this area. The abundance distribution of ANAMMOX bacteria was significantly positively correlated with total organic carbon content (P<0.01,r=0.69), reducing along with the increasing concentration of nitrite and DO, while the influence from salinity was complicated. |
