Description

General description

Peptone (vegetable) No. 2 is prepared under controlled conditions by enzymic digestion of vegetable proteins and therefore an animal-free alternative to traditional peptones. It has nutritional characteristics that match Gelatin peptones (Catalog No. 70176). It can be employed in media for fermentation studies: Purple Agar base, Sugar-free Agar, MacConkey Agars, Violet Red Bile Agar, etc.

Application

Peptone (vegetable) No. 2 is a universal complex media component that is used for the isolation and cultivation of microorganisms.
Vegetable peptone facilitates the growth of a broad range of microbes, from fastidious aerobic bacteria to yeasts and molds. It also prevents contamination from possible Bovine Spongiform Encephalopathy (BSE) or Transmissible Spongiform Encephalopathy (TSE).
It is also used in media fill tests to assess the quality of the aseptic filling process as stipulated by FDA guidelines
