In aerobic respiration, oxygen is absorbed and CO2 given off.
Further, they can be divided into two classes, the aerobic and the anaerobic.
Like the bacillus of splenic fever, the microbe of the fowl cholera is an aerobic organism.
The cause of this, no doubt, is that an aerobic parasite has always some difficulty in developing itself in the blood.
Second, running appears to be an especially effective way to derive specific therapeutic benefits from an aerobic activity.
The fermentation produced by the aerobic bacteria is most often met in bottled milk and cream during the warmer times of the year.
(a) The number of aerobic micro-organisms present per gramme of the soil.
(c) The number of aerobic organisms "growing at 37° C." present per gramme of the soil.
Gradually, as decay progresses, the aerobic organisms increase in number.
Anaerobic species usually require little oxygen, but aerobic species a free supply.
