Biological Activity

[Description]:

Yeast extract is a concentrate of the soluble part of yeast, especially Saccharomyces cerevisiae. The main nutritional components of yeast extract include partly hydrolyzed protein with 35-40% of free amino acid, and it also contain B vitamins and some trace elements. Yeast extract can be used as nutrients for bacterial culture media[1].
