摘 要：
甲烷是一种长期存在于大气中的温室气体,它对温室效应的贡献率是二氧化碳的26倍.生活垃圾填埋场是大气甲烷的主要产生源之一,由其产生的甲烷约占全球甲烷排放总量的1.5%～15%.甲烷氧化微生物在调节全球甲烷平衡中起着重要作用.垃圾填埋场覆土具有相当强的甲烷氧化能力.填埋覆土甲烷氧化菌及其氧化作用机理的研究,已成为环境微生物学研究领域的热点之一.本文对生活垃圾填埋场填埋覆土中甲烷氧化微生物、甲烷氧化机理及动力学机制、甲烷与微量填埋气体的共氧化机制以及影响甲烷氧化的环境因子研究的最新进展进行综述,并对生活垃圾填埋场甲烷氧化微生物的研究进行展望.

摘 要：
Methane is the second largest contributor after carbon dioxide to global warming,while landfill is considered as one of the major sources of methane emission,accounting for 1.5%-15% of the global methane sources.Methanotrophic microorganisms play an important role in regulating global methane content,and landfill cover soil is proved to have high capacity of methane oxidation.The study of methanotrophic microorganisms in landfill cover soil and their mechanisms in methane oxidation becomes one of the hot research fields in environmental science and applied microbiology.This review summarized the recent progress on the research of methanotrophic microorganisms,mechanisms and dynamics of microbial methane oxidation,co-metabolism of methane and trace landfill gases,and environmental factors affecting methane oxidation in landfill cover soil.Some perspectives for further research on methanotrophic microorganisms in landfill cover soil were discussed.
