| Below the depth of oxygen penetration life is restricted to anaerobic bacteria. |
| There are thus special design considerations associated with anaerobic systems, though methane can be recovered and used as a source of energy. |
| Sugar availability is one of the elements required to support anaerobic metabolism. |
| Parallel experiments were performed in acetonitrile and phosphate-buffered saline aqueous solutions under both aerobic and anaerobic conditions. |
| The odor results from the liberation of amines and organic acids produced from the alkalization of anaerobic bacteria. |
| Some experts say that after six to eight weeks of regular anaerobic exercise, a short hiatus is required to promote growth. |
