Abstract: Methanotrophs are members of Archaebacteria that play an important role in mitigation of climate change by reducing methane emissions from landfills and geothermal power stations. Two types of methanotrophs are existent in nature – high capacity methanotrophs and low capacity methanotrophs. Methane monooxygenase enzyme produced by these organisms plays a major role in utilization of methane as a sole source of carbon and energy. Two types of monooxygenases have been isolated from methanotrophs -soluble methane monooxygenase (sMMO) and particulate methane monooxygenase (pMMO).Cells with pMMO expressed high affinity for methane than sMMO producing cells. Methane gas is harmful to environment as it a potential greenhouse gas and is produced due to several anthropogenic activities. Methane is 72 times more potent than carbon dioxide in trapping heat in a period of 20 years. Hence formulation of new strategies is essential in environmental engineering by exploiting methanotrophs for reversal of global warming
