Overview
Malt Peptone MA2 is a soy and wheat and malt-derived peptone, used as a nitrogen and growth-factor source in culture media. It is suited to the cultivation of yeast and mold. Non-GMO, animal-free; contains gluten and soy allergens. Supplied by STBIO MEDIA with a COA for every batch; samples and specifications are available on request.
Choosing a plant peptone by raw material
Plant peptones contain no animal components, which suits Halal, vegetarian and animal-free formulations; raw materials differ in amino acid profile and allergens. Rice peptone carries a low allergen risk and suits gluten-free and hypoallergenic formulations. Pea and mung bean peptones contain no soy or gluten and often replace soy peptone. Wheat peptone is naturally rich in glutamine but contains gluten. Guar peptone is common in industrial fermentation. Plant peptone blends combine several raw materials designed for a given use. To avoid a particular allergen, check the allergen field on the product page first.

Frequently asked questions
01Can plant peptones fully replace animal peptones?
In most fermentation and cell culture it can, but it needs verifying. Animal peptones have an amino acid profile closer to microbial needs, and a single plant source may run low in some amino acids; the usual approach is to combine two plant peptones (pea with rice, for example) or use a plant peptone blend. Trial and compare growth curves and product.
