What is the role of peptone in Oxidation-Fermentation Medium?

Peptone plays a critical role in Oxidation-Fermentation Medium as it acts as a nitrogen source. Bacteria require nitrogen for various cellular processes, including the synthesis of proteins, nucleic acids, and other essential biomolecules. When peptone is included in the medium, it provides the necessary amino acids and peptides that support the growth of a wide variety of microorganisms.

While it is important for the medium to have carbohydrates as a source of energy, the distinction here is that peptone primarily contributes nitrogen rather than enhancing carbohydrate content or controlling acidity. Additionally, it does not inhibit oxidizers; rather, it supports the growth of both aerobic and anaerobic bacteria by ensuring they have enough nutrients to metabolize effectively.
