Question

.How do aerobic bacteria grow?

Answer 1

Aerobic bacteria:

1. These bacteria require oxygen for their survival and are key to the biological decomposition process.
2. Examples of such organisms are Pseudomonas aeruginosa, Escherichia coli, Klebsiella, and Salmonella.

Growth of aerobic bacteria:

1. Aerobes require oxygen for energy production and respiration processes.
2. They derive energy by carrying out oxidative phosphorylation and the Krebs cycle.
3. The aerobes use molecular oxygen available around them as terminal electron acceptors in the Krebs cycle.
4. They utilize oxygen to generate ATP molecules by glycolysis.
5. The key enzymes that help aerobes thrive are catalase, peroxidase, and superoxide dismutase.
6. These enzymes help neutralize the harmful effects of the reactive oxygen species generated.
