General description
Yeast extract is produced by various yeast species mainly by Saccharomyces cerevisiae or baker’s yeast. [1] In addition to its use as a supplement in culture media for microbial research and biotechnology, [1] yeast extract is also used as a component of the complex media for industrial fermentations.[2]It also serves as a nutritional source for various microbial media.
Application
For general bacteriological use with a variety of microorganisms.
Yeast Extract has been used as a component of:
Yeast extract is used as a bacteriological media component for a variety of microorganisms and molecular genetics applications.
Other Notes
Water soluble portion of autolyzed yeast with intact B-complex vitamins. Yeast extract is a mixture of amino acids, peptides, water soluble vitamins and carbohydrates and can be used as additive for culture media.
