Dimethyl ether
Dimethyl ether, also known as methyl ether or wood ether, is a colorless gas that has been used in refrigeration applications. If oxygenated on one of the carbon atoms, it will undergo spontaneous decomposition to methanol and formaldehyde. This has been demonstrated to be catalyzed by a nitrifying bacterium expressing ammonia monooxygenase. Dimethyl ether has also been shown to be oxidized by methanotrophic bacteria but it does not serve as a growth substrate for those bacteria [http://www.ncbi.nlm.nih.gov/pubmed/6802804|(Meyers, 1982).]
