جاندار بی‌هوازی: تفاوت میان نسخه‌ها

[[Image:Anaerobic.png|300px|thumb|right|Aerobic and anaerobic [[bacteria]] can be identified by growing them in test tubes of [[thioglycollate broth]]: <br /> 1: [[Obligateاندامگان aerobeهوازی]]s need oxygen because they cannot ferment or respire anaerobically. They gather at the top of the tube where the oxygen concentration is highest. <br /> 2: [[Obligate anaerobe]]s are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest. <br /> 3: [[بی‌هوازی اختیاری]] 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. <br /> 4: [[Microaerophile]]s 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. <br /> 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. ]]
