Do Anaerobic bacteria require oxygen

Answer 1

Anaerobic organisms obtain energy without using oxygen as the final electron acceptor. They use sulfate, nitrate or sulfur as the final electron acceptor. This doesn't form as much energy as oxygen will. These microbes do fill a niche that aerobes can't fill.

Answer 2

if you mean the type that survive at the bottom of the ocean then mainly through chemical reactions. at the bottom of the ocean there is no light and little if any oxygen. instead, there are vents that spew out chemicals from within the earth. the bacteria use these chemicals to fuel chemical reactions that allow the to live.

other types use photosynthesis, which is one of the ways scientist hypothesis oxygen first entered the atmosphere.

hope this helps!!!

Answer 3

Microorganisms such as bacteria and fungi absorb oxygen via diffusion through the cellular membrane. Diffusion is a simple physical process where molecules move from an area of high concentration to low concentration.

Many microorganisms do not require oxygen in order to respire as most are capable of anaerobic respiration. Anaerobic respiration takes place without oxygen and produces substances such as ethanol or lactic acid.

Answer 4

Bacteria obtains oxygen through the process of diffusion. When the bacteria is low on oxygen, the oxygen will begin to diffuse into the bacteria.

Answer 5

Anaerobic bacteria do not need to obtain oxygen so they don't obtain oxygen. This is because they don't use oxygen in any of their processes.

Answer 6

No, in fact anaerobic bacteria die in the presence of oxygen (an - no, aero- oxygen)

Answer 7

Bacteria utilize oxygen by using it in cellular respiration. Not all bacteria use oxygen however, as many types are anaerobic and it is toxic to them.
