General description

Yeast extract is produced by various yeast species mainly by Saccharomyces cerevisiae or baker’s yeast. In addition to its use as a supplement in culture media for microbial research and biotechnology, yeast extract is also used as a component of the complex media for industrial fermentations.It also serves as a nutritional source for various microbial media.

Application

Yeast Extract has been used as a component of:
  • complex media for culturing E. coli clones for shake flask experiments
  • culture media for culturing bacterial species Gluconacetobacter xylinus
  • yeast extract beef (YEB) media for the transformation of Agrobacterium
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.
