Question

What are obligate anaerobes?

Answer 1

Obligate anaerobes:

1. Obligate anaerobes are organisms that can grow and survive only in the absence of oxygen.
2. In aerobic conditions they tend to die. They are killed by normal atmospheric concentrations of oxygen (ie,20.95% O2)
3. During the growth and metabolic reactions of obligate anaerobes, oxygen reduction products are generated within the microbes and secreted into the surrounding medium.
4. Example, Clostridium botulinum, etc.
