#anaerobe

• Anaerobic — Said of organisms (bacteria, fungi) that can live, develop, or carry out their structural vital processes in the absence of free molecular oxygen; it also describes biochemical processes (fermentation, cellular respiration) taking place without the participation of oxygen. In sports physiology, it qualifies intense, short-duration physical efforts where energy is produced by breaking down carbohydrates without additional oxygen supply.
• Anaerobiont — A microorganism or lower organism that lives and structurally develops exclusively in an environment devoid of free molecular oxygen. This type of organism, primarily represented by denitrifying, methanogenic, or sulfate-reducing bacteria, obtains the energy required for its vital functions through alternative metabolic processes such as fermentation or anaerobic respiration.
• Anaerobe — A phonetic variant or outdated noun form for the term 'anaerob' (anaerobe); a microorganism, cell, or lower organism capable of living and structurally multiplying in an environment devoid of molecular oxygen. As an adjective, it describes biochemical processes or anoxic ecological environments where metabolism relies exclusively on alternative energy pathways that do not involve oxygen.
• Anaerophyte — A plant or lower vegetable organism that has the structural capacity to live, develop, or carry out its metabolic processes in environments completely devoid of free oxygen or with an extremely low concentration of it. This adaptive phenomenon is encountered in certain species of fungi, algae, or plant bacteria that inhabit flooded soils, deep muds, or sealed organic chambers, where respiration occurs through fermentative pathways.
