Description

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:

• complex media for culturing E. coli clones for shake flask experiments [3]
• culture media for culturing bacterial species Gluconacetobacter xylinus [4]
• yeast extract beef (YEB) media for the transformation of Agrobacterium [5]

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.
