Application

Yeast from Saccharomyces cerevisiae has been used:
  • in yeast sample preparation for tube-gel electrophoresis (TGE) fractionation
  • as a diet supplement to study its effect on the utilization of food waste as a diet for grass carp
  • for fermentation of miscanthus and the cellulose-rich extract samples to produce ethanol

Biochem/physiol Actions

Saccharomyces cerevisiae is a unicellular fungus. Yeast from S. cerevisiae is the widely used yeast species in bread and sourdoughs. It is used to produce several fermented beverages (cider, beer, 85s, and wine) and distilled beverages (brandy, sake, vodka, and whisky). S. cerevisiae has better tolerance for fermentation stresses than any other yeast species. Hence, it is a preferred starter culture for industrial fermentation.

Caution

Only approx. 10% will autolyze in aqueous buffer at 37 °C.

Preparation Note

Fast dried to yield 90% active, viable yeast in a convenient solid form.

Biofilm-related infections are a major contributor to human disease, and the capacity for surface attachment and biofilm formation are key attributes for the pathogenesis of microbes. Serratia marcescens type I fimbriae-dependent biofilms are coordinated by the adenylate cyclase, CyaA, and...

Indole and its derivatives have been shown to interfere with the quorum sensing (QS) systems of a wide range of bacterial pathogens. While indole has been previously shown to inhibit QS in Serratia marcescens, the effects of various indole derivatives...

As the process of top-down mass spectrometry continues to mature, we benchmark the next installment of an improving methodology that incorporates a tube-gel electrophoresis (TGE) device to separate intact proteins by molecular mass. Top-down proteomics is accomplished in a robust...

The vacuolar H+-ATPase, or V-ATPase, is a highly-conserved multi-subunit enzyme that transports protons across membranes at the expense of ATP. The resulting proton gradient serves many essential functions, among them energizing transport of small molecules such as neurotransmitters, and acidifying...
