| decomposition | 1. The act or process of resolving the constituent parts of a compound body or substance into its elementary parts; separation into constituent part; analysis; the decay or dissolution consequent on the removal or alteration of some of the ingredients of a compound; disintegration; as, the decomposition of wood, rocks, etc. 2. The state of being reduced into original elements. 3. Repeated composition; a combination of compounds. Decomposition of forces. Same as Resolution of forces, under Resolution. Decomposition of light, the division of light into the prismatic colours. Origin: Pref. De- (in sense 3 intensive) + composition: cf. F. Decomposition. Cf. Decomposition.

| decomposition of movement | A manifestation of cerebellar disease in which a muscular movement is not carried out smoothly but in a series of component motions. (05 Mar 2000) |
| anaerobic | 1. Lacking molecular oxygen. 2. Growing, living or occurring in the absence of molecular oxygen, pertaining to an anaerobe. (18 Nov 1997) |
| anaerobic bacteria | Bacteria which thrive in the absence of oxygen. (27 Sep 1997) |
| anaerobic digester | This is a bioreactor foranaerobically digesting sewage-laced wastewater.In it, anaerobic bacteriaproduce a mix of methane and carbon dioxide, asmuch as 90% of the chemical energy in the wastewater can be converted to methane, which is typically exhausted continuously and collected for useas a fuel or for a reagent for other industrial chemical reactions. (09 Oct 1997) |
| anaerobic digestion | A biochemical process by which organic matter is decomposed by bacteria in the absence of oxygen, producing methane and other byproducts. (05 Dec 1998) |
| anaerobic respiration | Respiration under anaerobic conditions. The terminal electron acceptor, instead of oxygen in the case of regular respiration, can be: carbon dioxide, Fe2+, fumarate, nitrate, nitrite, nitrous oxide, sulphur, sulphate, etc. Note that anaerobic respiration still uses the electron transport chain to dump the electron while fermentation does not. (09 Oct 1997) |
| anaerobic threshold | The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements. (12 Dec 1998) |
| gram-negative anaerobic bacteria | <microbiology> A large group of anaerobic bacteria which show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative anaerobic cocci | <microbiology> A group of anaerobic coccoid bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative anaerobic straight, curved, and helical rods | <microbiology> A group of anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative facultatively anaerobic rods | <microbiology> A large group of facultatively anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| anaerobic decomposition |
The breakdown of molecules into simpler molecules or atoms by microorganisms that can survive in the partial or complete absence of oxygen.
