Detailed explanation-1: -Bacteria that require oxygen to grow are called obligate aerobic bacteria. In most cases, these bacteria require oxygen to grow because their methods of energy production and respiration depend on the transfer of electrons to oxygen, which is the final electron acceptor in the electron transport reaction.

Detailed explanation-2: -Aerobic bacteria require oxygen for survival. They are present in aerated moist soil containing organic carbon sources. There are two main types of aerobic bacteria: 1.

Detailed explanation-3: -Aerobic bacteria need molecular oxygen for survival and growth. The reason is aerobic respiration in bacteria is used to derive energy from oxidative phosphorylation and Krebs cycle (also called TCA cycle or citric acid cycle) and some part of the energy from glycolysis.

Detailed explanation-4: -Bacteria can be classified by their need and tolerance for oxygen: Facultative: Grow aerobically or anaerobically in the presence or absence of oxygen. Microaerophilic: Require a low oxygen concentration (typically 2 to 10%) and, for many, a high carbon dioxide concentration (eg, 10%); grow very poorly anaerobically.
