Bacteria which prosper in the presence of oxygen are said to be aerobic. When oxygen is absent, the cardio germs can not live yet a different household of bacteria is created. These microorganisms are said to be anaerobic. Whilst they are equally with the ability of damaging down sludge, in so doing they create gases such as hydrogen sulphide and also methane.
