| hydrocarbon fuel | mixture of flammable liquid hydrocarbons principally used as fuel for internal combustion engines that can either:
- be derived from refining crude petroleum. (see gasoline)
or:
produced organically by fermentation : see fuel alcohol

| landfill gas | produced by microbial decomposition of landfilled materials, it has a chemical composition not unlike biogas, but with additional components such as siloxanes, which present problems at time of using the gas for fuel purposes. Agriculturally produced biogas is normally free from siloxanes.

methanogens
Author: webmaster | Common name of organisms requiring completely anaerobic conditions for growth and producing methane gas as a catabolic product. Methanogens are members of the archaea and are found in the bovine stomach, swamp mud, and other environments in which oxygen is not present. There are four basic taxonomic orders: methanobacteriales, methanococcales, methanomicrobiales, and methanosarcinales. |
