#aerotaxis

• Aerotaxis — A specific form of taxis or directed orientation and movement reaction of mobile microorganisms (bacteria, protozoa) triggered by the presence, concentration level, or partial pressure variation of oxygen or other gases in their living environment. This structural phenomenon guides aerobic bacteria toward oxygen-rich zones and anaerobic ones away from them.
• Aerotaxis — A specific form of taxis encountered in motile microorganisms, consisting of a reflex movement of orientation and displacement toward or away from a source of oxygen or other gases. This structural biological mechanism governs the attraction of aerobic bacteria to zones with optimal air concentration and the repulsion of strict anaerobes from oxygenated environments.
