Description

General description

M-Gredient^® Casein Peptone A1 (Tryptone) Pancreatically Digested, Granulated, Prime, for Biotechnology and Microbiology is obtained by pancreatic digestion of acid precipitated, food-grade casein, bovine casein using porcine pancreatin. It is a commonly used peptone known for its high tryptophan content, that can be deployed individually or blended with soy, yeast extract, or meat peptones. It supports the vigorous growth of lactic acid bacteria, yeasts, and filamentous molds. Its low calcium content makes it appropriate for culture media with elevated phosphate levels.

Our special granulation of the casein peptone ensures rapid and uniform dissolution in water, as well as convenient and safe handling, as it prevents clumping and inhalation of the airborne powder.

Application

Peptone from casein is commonly used as an ingredient in many microbial culture media for the growth and identification of bacteria, yeasts and molds from various pharmaceutical, environmental, food and beverage samples.

Features and Benefits

Our Granulated media are:

Safer - Significant reduction of inhalation of toxic and allergenic substances resulting in fewer allergic responses. Less contamination of working tools and environment
Accurate - No separation of components and no clumping, even under humid or warm conditions, ensure a uniform product with higher performance accuracy
Fast - Rapid and uniform dissolution in water
Easier - Easier handling and weighing due to the better flow properties. Media do not stick to the flask or container
Reliable - Homogenous distribution of ingredients guarantees high reproducibility even if only small amounts of media are used.
