Answer 2

Step-by-step explanation:

Aerobic bacteria:

The bacterias that grow in the presence of oxygen are called aerobic bacteria. It has the ability to detoxify oxygen with the help of enzymes. The final electron acceptor is molecular oxygen. Water is produced from the final electron acceptor. When in liquid medium they are seen on the surface of the medium. Example: Nocardia, Bacillus.

Anaerobic bacteria:

The bacterias that grow in the absence of oxygen are called anaerobic bacteria. It does not have the ability to detoxify oxygen. The final electron acceptor is carbon dioxide, sulfur, fumarate or ferric. Acetate like substances, methane, nitrate and sulfide is produced from these bacterias. When in liquid medium they are seen at the bottom of the medium. Example: Bacteroids, E.Coli

To make you understand how aerobic and anaerobic bacteria are different from each other, here are the some of the major differences between aerobic and and anaerobic bacteria:

Difference between Aerobic and Anaerobic

AEROBIC

ANAEROBIC

Need air to survive

Do not require air to survive

Produce more energy

Produce less energy

Molecular oxygen is the final electron acceptor

Carbon dioxide, sulfur, fumarate or ferric is the final electron acceptor

Bacterias are seen on the surface of liquid

Bacterias are settled at the bottom of the liquid

Example: Mycobacterium tuberculosis

Example: Clostridium
