Methane (CH4) is a hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 21.

Methanol (CH3OH) is a colorless poisonous liquid with essentially no odor and little taste. It is the simplest alcohol with a boiling point of 64.7 °C (degrees Celsius). 

A Methanotrophic is Having the biological capacity to Oxidize Methane to CO2 and water by metabolism
