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.
Bacteria are differnet in many unique ways such as their shape. There are rod, sphere, and spiral shaped bacteria. There are also archaebacteria and eubacteria. Archaebacteria need no oxygen while others do. They also grow at different rates, their environment is different, etc. Pretty cool, isn't it??

An anaerobic infection is an infection caused by bacteria (called anaerobes) which cannot grow in the presence of oxygen.
Actually the liquid agar medium is used in the petridishes to grow the colonies of bacteria. The nutritional environment available to the bacteria results in to faster growth of their colonies and also they can be used for the experiments more rapidly
No, bacteria do not grow on fat
Not all bacteria do. Some can not grow in the presence of oxygen. Those that do (obligate aerobes and facultative anaerobes) grow quicker in oxygen since it facilitiates their energy cycle and ideal environment.
Anaerobic bacteria don't need oxygen to grow.
Obligate aerobes require oxygen to make energy , grow and multiply . If the environment is lacking in oxygen, they will die. This is not exactly suffocation. See link below:
The condition that helps aerobic bacteria to grow and thrive is oxygen. In stark contract an anaerobic organism does not require oxygen to grow and thrive.
Aerobic bacteria uses oxygen for cellular respiration and anaerobic bacteria doesn't require oxygen to survive. ˇ_ˇ 
The amount of bacteria that could breed in a given time would depend on several factors. Bacteria require a source of nutrients, a warm environment, an energy source such as oxygen, and pH to grow and reproduce quickly.

The factor is Oxygen.
Bacteria and Salmonella grow in warm conditions. Too hot or cold will kill them and so a warm, wet environment is perfect for them to grow.
may be that antibiotics has killed the bacteria or the environment is not suited to grow a culture
Bacteric grow faster in places where there is enough moisture, food and oxygen...our mouth!
