Best Answer

Microbes or bacteria that grow in an anaerobic environment don't need oxygen. They cannot generate energy through aerobic respiration and must employ fermentation or anaerobic respiration for this purpose. They can be: FACULTATIVE ANAEROBES: do not require oxygen for growth, but grow better in its presence. AEROTOLERANT ANAEROBES: such as Enterococcus faecallis, simply ignore oxygen and grow equally well whether it is present or not. STRICT/OBLIGATE ANAEROBES: do not tolerate oxygen at all and die in its presence, e.g., Bacteroides, Fusobacterium, Clostridium pasteurianum, Methanococcus, Neocallimastix, etc.

Anaerobic bacteria are organisms that can survive and thrive in the absence of oxygen. Examples include Clostridium botulinum, which causes botulism, and Bacteroides fragilis, a common inhabitant of the human gut that can cause infections when it enters other body sites.

aerobic bacteria i would know because that's what were learning right now in sixth grade. These aerobic bacteria include the bacteria that cause Pnemonia, which like to inhabit inside the lungs of Humans, where there is a rich supply of oxygen.

i agree with this and this is a different person :)

Hope you don't want the whole list :)

It would be the anerobic and facultative anerobic bacteria.

How much oxygen does stearothermophilus need?

Stearothermophilus is a thermophilic bacterium that requires oxygen for its metabolic processes. The exact amount of oxygen it needs can vary depending on factors such as growth conditions and environment. Generally, stearothermophilus would require a sufficient supply of oxygen to support its metabolic activity.
