metho-, meth- +
(a combining form meaning methyl)
methane (s) (noun), methanes (pl)
A colorless, odorless, highly flammable gas, the simplest of the alkanes, which is produced by decaying organic matter and in the guts of ruminants, occurs in natural gas and coal gas, and is used as a fuel.
methanogen (s) (noun), methanogen (pl)
A methanogenic organism; specifically, any of the group of methane-producing archaebacteria that are found in anaerobic environments and in the guts of animals; especially, ruminants and arthropods.
methanogenesis (s) (noun)
The production of colorless, gaseous, inflammable hydrocarbons with living organisms: "Methanogenesis is the formation of methane from microbes that exist in fresh-water or marine sediments, in the intestinal tracts of animals, or in places constructed by humans; such as, sludge in sewage or biomass digesters all of which come from the anaerobic microbial food chain."
"In biotechnology, methanogenesis is the last step in the artificial production of methane, during which hydrogen and bicarbonate are processed into methane."
methanogenic (adjective), more methanogenic, most methanogenic
Producing natural gas; specifically, designating archaebacteria or ancient single-celled micro-organisms:" "The methanogenic life forms are said to have many differences in their biochemistry from other biological organisms."
methanol (s) (noun),
The simplest of the aliphatic alcohols, a colorless, volatile, flammable, toxic liquid: "Methanol, which is also called methyl alcohol, or wood alcohol, was originally obtained by the distillation of wood and is used in chemical synthesis, as a solvent, and as an alternative fuel."
Of, dissolved in, or diluted with methanol.
methanolysis (s) (noun)
Alcoholysis using methanol; that is, a chemical reaction in which a compound reacts with an alcohol, causing decomposition and producing two or more new compounds.
methanometer (s) methanometers (pl) (noun forms)
An instrument for measuring the concentration of methane in air; especially, in coal mines.
methanophile (s) (noun), methanophiles (pl)
An organism capable of oxidizing methane or bacteria that are able to metabolize methane as their only source of carbon and energy.
methanotroph (s), methanotrophs (pl) (noun forms)
Any of a group of aerobic bacteria capable of utilizing methane as a carbon and energy source.
ventilation air methane (VAM)
Methane released to the atmosphere from the ventilation systems of underground coal mines; because methane is a greenhouse gas, technologies have been developed to degasify the ventilation air by means of oxidation.
