General description
A water-soluble extract of autolyzed yeast cells, yeast extract is a mixture of amino acids, peptides, and water-soluble vitamins, for example, intact vitamin B12 complex and carbohydrates, and can be used as an additive for culture media and fermentation media. It can also be used in the resuscitation of a large variety of fastidious microorganisms.
Application
Yeast extract is recommended for use in culture media and the cultivation of various microorganisms. It provides multi-functional nutrient supplements that can also be used in microbial fermentation.
