Anaerobic

Anaerobic

Anaerobic is a technical word which literally means "without air" (where "air" is generally used to mean oxygen), as opposed to aerobic.

In wastewater treatment the absence of oxygen is indicated as "anoxic"; and "anaerobic" is used to indicate the absence of a common electron acceptor such as nitrate, sulfate or oxygen. An anaerobic adhesive is a bonding agent that does not cure in the presence of air.
