Methanotrophs use methane as a sole carbon and energy source and play an important role in the balance of atmospheric methane. They can also degrade halogenated hydrocarbons,which has potential value in contamination bioremediation.Based on the taxonomy of methanotrophic bacteria,a preliminary conclusion was drawn on the mechanism of methane oxidation by methanotroph,its physiology and distribution in ecosystems, and methods to study methane-oxidizing bacteria,as well as potential use of methanotroph in biodegradation of toxic chemicals.In this paper we also analyzed the current problems in the studies of methanotrophs,and pointed out the directions for future research work in this field.
