General description

Peptone from an enzymatic digest of casein is used as a nitrogen source in culture media formulated for isolating and cultivating fastidious and non-fastidious bacteria and fungi. It is a refined hydrolysate with high solubility and is used as a microbiological nutrient. It is a rich source of amino acids and peptides recommended for culture media in analytical microbiology and industrial fermentation.

Application

Peptone from casein may be used as medium supplement in the following:
Bacterial cultures for short term storage of bacteria.
The basal Glucose Yeast Peptone (GYP) medium.
As nitrogen supplement in the culture medium of Ceriporiopsis subvermispora.
Culture medium of Methylobacterium rhodesianum and Ralstonia eutropha.

Base Ingredients of Microbiology Media

Culture media provides a habitat with suitable nutrients, energy sources, and certain environmental conditions for the growth of microorganisms. The components of the culture media range from simple sugars to peptones, salts, antibiotics, and complex indicators.

Bacterial antagonists are bacteria that negatively affect the growth of other organisms. Many antagonists inhibit the growth of fungi by various mechanisms, e.g., secretion of lytic enzymes, siderophores and antibiotics. Such inhibition of fungal growth may indirectly support plant growth.
