| Parallel experiments were performed in acetonitrile and phosphate-buffered saline aqueous solutions under both aerobic and anaerobic conditions. |
| River water begins to putrefy when lack of oxygen promotes the growth of anaerobic bacteria, which produce the tell-tale smell of stale water. |
| They found the samples contained anaerobic bacteria that grew on sugars and proteins in total absence of oxygen. |
| Thermatoga microorganisms are known to play a role in the anaerobic oxidation of hydrocarbons to alcohols, organic acids and carbon dioxide. |
| The odor results from the liberation of amines and organic acids produced from the alkalization of anaerobic bacteria. |
| There are thus special design considerations associated with anaerobic systems, though methane can be recovered and used as a source of energy. |
