Description

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.[1]
The basal Glucose Yeast Peptone (GYP) medium.[2]
As nitrogen supplement in the culture medium of Ceriporiopsis subvermispora.[3]
Culture medium of Methylobacterium rhodesianum and Ralstonia eutropha.[4]
