Anaerobic: A process that takes place in the absence of oxygen, such as the digestion of organic matter by bacteria in a UASB-reactor.
anaerobic (AN-air-O-bick). A condition in which "free" (atmospheric) or dissolved oxygen is NOT present in water.
analog. The readout of an instrument by a pointer (or other indicating means) against a dial or scale.
anaerobic : A biological process which occurs in the absence of oxygen.
aqueous solubility : The extent to which a compound will dissolve in water. The log of solubility is generally inversely related to molecular weight.
Anaerobic Respiration - Living or acting in the absence of oxygen. Cellular respiration in the absence of oxygen. [Microbiology; v140; 2153-2158; 1994.] [Journal of Bacteriology; v176; 5086-5092; 1994.] ...
Anaerobic
A life or process that occurs in, or is not destroyed by, the absence of oxygen.
Anaerobic Decomposition ...
Anaerobic Decomposition: Reduction of the net energy level and change in chemical composition of organic matter caused by microorganisms in an oxygen-free environment.
Animal Dander: Tiny scales of animal skin, a common indoor air pollutant.
anaerobic Capable of living in the absence of air or free oxygen.
anaerobic A condition in which free or dissolved oxygen is not present in water.
Anaerobic
Anaerobic refers to occurring or living without oxygen present.
Anhydrous Ammonia ...
Anaerobic process A process which only occurs in the absence of molecular oxygen.
Anoxic process A process which occurs only at very low levels of molecular oxygen or in the absence of molecular oxygen.
Anaerobic: In the absence of oxygen.
Analog: In chemistry, a structural derivative of a parent compound.
Analysis Date/Time: The date and military time of the injection of the sample, standard, or blank into the GC/MS or GC system.
Aerated and anaerobic conditions can occur in close proximity. These aerobic (red) and anaerobic (grey) soils were taken from a transect across a terrace that was less than 200 yards long.
anaerobic (1) in the absence of oxygen; (2) pertaining to organisms capable of respiration in the absence of oxygen.
angiosperms "vessels for seeds." Flowering plants. The class Angiospermae, within the division Tracheophyta.
A mixture of methane (CH4) and carbon dioxide (CO2) produced by anaerobic digestion, with small amounts of other gases.
Processes which employ aerobic or anaerobic microorganisms and result in decanted effluents and separated sludge containing microbial mass together with pollutants.
Methane is produced through anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, ...
Landfills Too Tightly Packed for Most Trash to Biodegrade
Most landfills are fundamentally anaerobic because they are compacted so tightly, and thus do not let much air in. As such, any biodegradation that does take place does so very slowly.
Bacteria that can live under aerobic or anaerobic conditions.

...
Putrefaction: Biological decomposition of organic matter; associated with anaerobic conditions.
Putrescible: Able to rot quickly enough to cause odors and attract flies.
Pyrolysis: Decomposition of a chemical by extreme heat.
landfill: disposal of solid waste by burying it between layers of dirt in low-lying ground or excavated holes. Organic matter in landfill decomposes anaerobically (without air), gives off the greenhouse gas methane, ...
Facultative Bacteria- Bacteria that can live under aerobic or anaerobic conditions.
Methane - A colorless, nonpoisonous, flammable gas created by anaerobic decomposition of organic compounds.

Putrefaction: Biological decomposition of organic matter, with the production of ill smelling and tasting products, associated with anaerobic (no oxygen present) conditions.

Wetlands: Habitats flooded with shallow water all or part of the year. Can be identified by unique plants which have adapted to oxygen-deficient (anaerobic) soils. Wetlands influence stream flows and water quality.
denitrification
Reduction of nitrates to nitrites, nitrogen oxides or dinitrogen (N2) catalysed by facultative aerobic soil bacteria under anaerobic conditions.
Anaerobic decomposition A process of breakdown of organic molecules to simpler inorganic constituents, that occurs in the absence of oxygen.
