Description

General description

Casein hydrolysates are used in the formulation of culture media for the cultivation of heterotrophic microorganisms. N-Z-Case^® Plus is a high-quality source of peptides produced by enzymatic digestion of casein. It is a uniform, high quality peptone providing superior growth characteristics. N-Z-Case^® Plus is refined hydrolysate, with very high solubility and clarity in solution. It is used in laboratory media and fermentation, especially where high clarity of solution is required.

Application

Casein hydrolysates are used in the formulation of culture media for the cultivation of heterotrophic microorganisms. This casein hydrolysate suits for the growth of probiotics (Bifidobacterium, Lactobacillus), starter cultures and media for diagnostics

Other Notes

Enzymatic hydrolysis has been optimized to produce rich growth of most bacteria.
