Aerotolerant anaerobe (original) (raw)

Property Value
dbo:abstract Aerotolerant anaerobes use fermentation to produce ATP. They do not use oxygen, but they can protect themselves from reactive oxygen molecules. In contrast, obligate anaerobes can be harmed by reactive oxygen molecules. There are three categories of anaerobes. Where obligate aerobes require oxygen to grow, obligate anaerobes are damaged by oxygen, aerotolerant organisms cannot use oxygen but tolerate its presence, and facultative anaerobes use oxygen if it is present but can grow without it. Most aerotolerant anaerobes have superoxide dismutase and (non-catalase) peroxidase but don't have catalase. More specifically, they may use a /NADH peroxidase (NOX/NPR) system or a glutathione peroxidase system. An example of an aerotolerant anaerobe is Cutibacterium acnes. (en) 산소내성 혐기성 미생물(aerotolerant anaerobe)은 무산소적으로 에너지 대사를 하기 때문에 산소가 필요없는 미생물이다. 이 미생물은 절대혐기성 미생물과 달리 산소의 독성을 제거할 수 있는 효소가 있다. 따라서 이 미생물은 배양 튜브의 전체에 골고루 퍼져서 자란다. 산소내성 혐기성 미생물은 초과산화물 불균등화효소(superoxide dismutase)와 과산화효소(peroxidase)는 있지만 카탈레이스(catalase)는 없다.
