好氧生物

由细菌在试管中的分布情况可以看出其异化类型:1.专性需氧(Obligate aerobic)细菌2.专性厌氧(Obligate anaerobic)细菌3.兼性(Facultative)菌4.微需氧(Microaerophiles)细菌5.耐氧(Aerotolerant )细菌

好氧生物英语:Aerobic organism,或 aerobe),又译为好气生物耗氧生物需氧生物,是能在有氧的环境中生存及生长的生物。好氧生物利用氧的化学反应来分解糖及脂肪,以获得能量。几乎所有的动物,大多数的真菌,都属于好氧生物。能在无氧环境中生存的生物,称为厌氧生物。根据对于氧气的需求,好氧生物又分为专性需氧生物、兼性好氧生物及耐微氧生物。

好氧生物主要进行有氧气参与的有氧呼吸。

Aerobic organism 好氧生物

Aerobic and anaerobic bacteria can be identified by growing them in test tubes of thioglycollate broth:  1: Obligate aerobes need oxygen because they cannot ferment or respire anaerobically. They gather at the top of the tube where the oxygen concentration is highest.  2: Obligate anaerobes are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.  3: Facultative anaerobes can grow with or without oxygen because they can metabolise energy aerobically or anaerobically. They gather mostly at the top because aerobic respiration generates more ATP than either fermentation or anaerobic respiration.  4: Microaerophiles need oxygen because they cannot ferment or respire anaerobically. However, they are poisoned by high concentrations of oxygen. They gather in the upper part of the test tube but not the very top.  5: Aerotolerant organisms do not require oxygen as they metabolise energy anaerobically. Unlike obligate anaerobes however, they are not poisoned by oxygen.  They can be found evenly spread throughout the test tube.

An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment.
