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.

Preparation Note

Dried to avoid inactivation of enzymes.

Disclaimer

Autolyzes in aqueous buffer at 37 °C.

Domande

1–2 di 2 domande  
  1. Hi We would like to expand this yeast in our lab for an experiment. Would you please recommend best growth media for expanding this Yeast.

    1 risposta
    1. This product is specifically prepared to undergo autolysis in aqueous buffer solution at 37°C, optimized for retaining enzyme activity post-drying, though not for cell viability or growth. It serves as an excellent starting point for enzyme extraction processes. For proliferation, Product YSC2 is a viable baker’s yeast, ready to grow once rehydrated, with only about 10% subject to autolysis at the same temperature. It is the preferred option for those looking to cultivate yeast effectively.

      Utile?

  2. What are the differences between YSC1 and YSC2?

    1 risposta
    1. YSC1 is dried to prevent enzyme inactivation during enzyme extractions from yeast. On the other hand, YSC2 is fast dried and yields 90% viable cells in solid form. The primary difference lies in the method of preparation, particularly in the drying process.
