在美国，城市固体废物（MSW）填埋场是甲烷排放的主要人为来源之一。在垃圾填埋场的覆盖土壤中，好氧甲烷氧化细菌（MOB）将CH4转化为CO2，从而部分缓解了CH4排放到大气中。本研究采用非培养和培养相结合的方法对垃圾填埋场覆盖土的甲烷氧化能力和微生物群落结构进行了研究。用合成填埋气顶空的微宇宙来测量填埋场覆盖土壤和甲烷氧化菌富集的微生物群落中的潜在甲烷氧化速率。结果表明，富集的填埋场覆盖土壤支持不同的甲烷氧化菌和甲基氧化菌群的生长，并以I型甲烷氧化菌为主，与CH4氧化速率呈正相关。
In the USA, municipal solid waste (MSW) landfills constitute one of the major anthropogenic sources of methane emissions. In the landfill cover soils employed at MSW landfills, aerobic methane-oxidizing bacteria (MOB) convert CH4to CO2, thereby partially mitigating the CH4emissions to the atmosphere. In this study, culture-dependent and culture-independent techniques were employed to evaluate methane oxidation capacity and to characterize the microbial community in landfill cover soil. Microcosms with synthetic landfill gas headspace were used to measure potential methane oxidation rates in landfill cover soil and in methanotrophs-enriched microbial consortia. The results demonstrate that the enriched landfill cover soil supported the growth of a diverse group of methanotrophic and methylotrophic microorganisms, and were dominated by Type I methanotrophs showing positive correlation with CH4oxidation rates.
