Sorry, no etymologies found.
The host (facultative aerobe implies facultative anaerobe, doesn't it?) could handle aerobic conditions already, presumably because it had peroxisomes as oxygen sink. t's funny that you mention peroxisomes, as people once thought they were endosymbionts but now evidence seems to point to en origin from the ER.
Yeast is a facultative anaerobe--that does not mean, however, that it does not appreciate a breath of oxygen now and then.

Another example is Clostridium thermocellulum, a thermophilic anaerobe that can utilize cellulose (MIT process).
It occurred to us that the septic vibrio might be an obligatory anaerobe and that the sterility of our inoculated culture fluids might be due to the destruction of the septic vibrio by the atmospheric oxygen dissolved in the fluids.
Obvious growth in the closed branch as well as in the bulb or in the inverted gas tube as well as in the bulk of the medium will indicate that it is a facultative anaerobe; whilst growth only occurring in the bulb or in the closed branch shows that it is an obligate aerobe or anaerobe respectively.
As a result of these rapid subcultures, the facultative anaerobe will be secured in pure culture at about the third or fourth generation.
~ -- The question as to whether the organism under observation is (a) an obligate aerobe, (b) a facultative anaerobe, or
"Yesterday I found that anaerobe cultures were being received by some one in the Belleclaire, and --"
The disease is caused by a common bacterium, Streptococcus pneumoniae, or pneumococcus, a gram-positive, alpha-hemolytic, bile soluble aerotolerant anaerobe, which can attack different parts of the body.
