oxygentolerant
Oxygentolerant is an adjective used in biology to describe organisms or systems that can withstand exposure to molecular oxygen. In microbiology, the term is often used interchangeably with aerotolerant to denote microbes that do not require oxygen for growth but can survive in its presence, in contrast to obligate aerobes that require oxygen and obligate anaerobes that are harmed by it.
Oxygen tolerance is often due to enzymes that detoxify reactive oxygen species, such as superoxide dismutase,
In bacteria, common examples of aerotolerant (oxygentolerant) taxa include many lactic acid bacteria such as Streptococcus
The concept is clinically and industrially relevant, affecting pathogenic potential, survival in oxygenated tissues, and product
