Methane utilizing bacteria and their biotechnological applications.
Methanotroph microorganisms oxidize methane in four steps, producing methanol, formaldehyde, formate intermediers and eventually degrade methane to carbon dioxide and water. It is possible to separate the pathway into four steps in the cell free extract or after partial purification of the various enzymes. The key enzyme is a metalloenzyme, methane monooxygenase (MMO) which catalyses the oxidation of methane to methanol. MMO is also capable of biodegrading exceptionally harmful and stable chlorinated hydrocarbons. Produced by various industrial activities, most chlorinated hydrocarbons are toxic, potential and/or proven carcinogens and their decomposition challenges water treatment technologies.
