英文摘要	Denitrifying anaerobic methane oxidation (DAMO) and associated microbial diversity and abundance in the marsh sediments of Chongming eastern intertidal flat, the Yangtze Estuary, were investigated using carbon-isotope tracing and molecular techniques. Co-existence of nitrate-DAMO archaea and nitrite-DAMO bacteria was evidenced, with higher biodiversity of DAMO archaea than DAMO bacteria. Abundance of DAMO archaeal mcrA gene and DAMO bacterial pmoA gene ranged from 4.2 × 103 to 3.9 × 1010 copies g−1 and from 4.5 × 105 to 6.4 × 106 copies g−1, respectively. High DAMO potential was detected, ranging from 0.6 to 46.7 nmol 13CO2 g−1 day−1 for nitrate-DAMO and from 1.3 to 39.9 nmol 13CO2 g−1 day−1 for nitrite-DAMO. In addition to playing an important role as a CH4 sink, DAMO bacteria also removed a substantial amount of reactive nitrogen (29.4 nmol N g−1 day−1) from the intertidal sediments. Overall, these results indicate the importance of DAMO bioprocess as methane and nitrate sinks in intertidal marshes. © 2019
