AbstractRecent investigations demonstrate that some coastal wetlands are atmospheric methane sinks, but the regulatory mechanisms are not clear. Here, the main pathway and operator of methane oxidation in the Yellow River Delta (YRD) wetland, a methane source in the wet season but a methane sink in the dry season, were investigated. The anaerobic oxidation of methane (AOM) and aerobic methane oxidation (AMO) abilities of wetland soil were measured, and the microbial community structure was analyzed. The experimental results showed that AMO was active throughout the year. In contrast, AOM was weak and even undetected. The microbial community analysis indicated that Methylomicrobium and Methylobacter potentially scavenged methane in oxic environments. A representative strain of Methylobacter, which was isolated from the soil, presented a strong AMO ability at high concentrations of methane and air. Overall, this study showed that active AMO performing by Methylobacter may account for methane sink in the YRD wetland during the dry season. Our research not only has determined the way in which methane sinks are formed but also identified the potential functional microbes. In particular, we confirmed the function of potential methanotroph by pure culture. Our research provides biological evidence for why some wetlands have methane sink characteristics, which may help to understand the global methane change mechanism. (C) 2019 Elsevier B.V.
