Mechanism of hypoxia-tolerance and community structure of aerobic methanotrophs in O2-limited environments: A review
Methane bio-oxidation plays an important role in the global methane balance and green-house gases mitigation.Oxygen (O2) is one of the significant factors in methane bio-oxidation.The O2 concentration in the environments not only can affect community structure and activity of aerobic methanotrophs and the distribution of methane-derived carbon,but also aerobic methanotrophs have various ways of metabolism at different O2 concentrations.It is meaningful for carbon cycle and biodiversity of methane-driven ecosystem to understand the hypoxia-tolerance mechanisms of aerobic methanotrophs and methane bio-oxidation in O2-limited environments.In this paper,the activity and community structure of aerobic methanotrophs in O2-limited environments were summarized.The hypoxia-tolerance mechanism of aerobic methanotrophs and the relationship between methanotrophs and non-methanotrophs in O2-limited environments were reviewed.Future studies about aerobic methanotrophs were also discussed.
