General description

Yeast from Saccharomyces cerevisiae (Baker′s yeast) is the oldest microbial starter. It is a facultative anaerobe.

Application

Yeast from Saccharomyces cerevisiae has been used:
  • as a biocatalyst for the anode of yeast microbial fuel cell
  • for the production of ethanol for fuel use
  • to prepare yeast extract

Biochem/physiol Actions

Yeast from Saccharomyces cerevisiae (Baker′s yeast) is used as a protein supplement, energy booster and immune enhancer. It serves as a dough leavening agent in bread production by converting the fermentable sugars to CO2 and ethanol. Baker′s yeast exhibits aroma, anti-molding and nutritive properties. It acts as a cell factory.

Caution

Autolyzes in aqueous buffer at 37 °C.

Preparation Note

Dried to avoid inactivation of enzymes.

Storage Class Code
