What Is Casein Tryptone?
Casein tryptone, CAS 91079-40-2, is a soluble casein hydrolysate that supplies peptides, amino acids and organic nitrogen for microbial growth. It is used in culture media for bacteria and fungi, in industrial fermentation, and in vaccine and enzyme production.
The specification sets total nitrogen ≥12% and amino nitrogen ≥3%, pH 5.0–7.0, with limits on ash and moisture. It dissolves completely in water.
It is not regulated as dangerous goods. Keep bags sealed, as the powder absorbs moisture. Pharmaceutical and diagnostic uses need a grade qualified for that purpose.
As a casein tryptone supplier and exporter in China, ZXCHEM packs the light yellow powder in 25 kg lined bags.
