英文摘要	Nitrite-dependent anaerobic methane oxidation (n-damo), catalyzed by microorganisms affiliated with bacterial phylum NC10, can have an important contribution to the reduction of the methane emission from anoxic freshwater sediment to the atmosphere. However, information on the variation of sediment n-damo organisms in reservoirs is still lacking. The present study monitored the spatial change of sediment n-damo organisms in the oligotrophic freshwater Xinfengjiang Reservoir (South China). Sediment samples were obtained from six different sampling locations and two sediment depths (0-5 cm, 5-10 cm). Sediment n-damo bacterial abundance was found to vary with sampling location and layer depth, which was likely influenced by pH and nitrogen level. The presence of the n-damo pmoA gene was found in all these samples. A remarkable shift occurred in the diversity and composition of sediment n-damo pmoA gene sequences. A variety of distinctively different n-damo pmoA clusters existed in reservoir sediments. The pmoA sequences affiliated with Candidatus Methylomirabilis oxyfera formed the largest group, while a significant proportion of the obtained n-damo pmoA gene sequences showed no close relationship to those from any known NC10 species. In addition, the present n-damo process was found in reservoir sediment, which could be enhanced by nitrite nitrogen amendment.; Integration Research and Demonstration of Water Quality Conservation and Ecological Restoration Technology of Urban Lake Landscape Water: the Major Projects of Synergy Creation of Production, Learning and Research of Guangzhou [201508020078]; National Natural Science Foundation of China [50908095, 41001323]; SCI(E); ARTICLE; 2; 165-174; 67
