DO YOU KNOW THAT...
Do anaerobic bacteria generally have longer lifespans than aerobic bacteria?
The answer to this is yes. Anaerobic growth is less energetic because most alternative electron acceptors (since oxygen isn't an option) have less reduction potential. So, less cellular energy is available to undergo division or anything else for that matter.
2. Can anaerobic bacteria survive in space?
No. Only absence of oxygen isn't enough for the survival of bacteria. It needs a carbon source (nutrients) to make their food and for their survival which isn't available in space.
3. Can bacteria survive in extreme temperature, like inside sun?
No, bacteria cannot withstand at high temperature. Not only bacteria no other organism can survive at such temperature.
4. Is it possible for aerobic bacteria to grow in the absence of oxygen?
There are different types of aerobic bacteria. Answer to the question depends on whether the bacterium is an Obligate aerobe or Facultatively anaerobe or Microaerophile or Aerotelerant.
