Bacteria that can ONLY grow in the absence of oxygen are called obligate anaerobes.
Microbes that can live in the presence or absence of oxygen are called facultative anaerobes. The microbial production of alcohol from sugar is known as fermentation.

only anaerobic(oxygen free) bacteria survives .
No, it is required only in cellular respiration. Fermentation takes place in the absence of oxygen.
obligate anaerobes
An anaerobe is an organism that grows without air. The organism can only live in oxygen-free conditions. If oxygen is present, the organism could die.
It depends--there are both aerobic (oxygen-dependent or oxygen-tolerating) and anaerobic (oxygen-intolerant) bacteria. Anaerobic bacteria often cannot live in the presence of oxygen, while increasing oxygen levels for aerobic bacteria can often stimulate population growth.
JEWS
Because the peptone iron agar is used to detect ANAEROBIC bacteria. If you stab it deep into the agar you allow the bacteria to grow in the absence of oxygen. If you only inoculated the surface the bacteria wouldn't grow.
Obligate anaerobes
Burning (oxydation, reaction with oxygen) is possible only when oxygen exist.
No. Only a nuclear reaction can change oxygen into nitrogen, and bacteria are not capable of such reactions.
human intestine
it can produce energy in the presence and absence of oxygen unlike aerobic exercise which can only produce energy in the presence of oxygen
No, it is required only in cellular respiration. Fermentation takes place in the absence of oxygen.
only anaerobic(oxygen free) bacteria survives .
obligate anaerobes
If they CAN survive without oxygen, they are called facultative anaerobes. In other words, these can survive with or without oxygen.If they CAN ONLY survive if there is no oxygen, they are callled obligate anaerobes. In other words, these can only survive if there is no oxygen.
Anaerobic Respiration occurs only in the absence of Oxygen.
