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.

Insects, unlike vertebrates, are widely believed to lack male-biased sex steroid hormones1. In the malaria mosquito Anopheles gambiae, the ecdysteroid 20-hydroxyecdysone (20E) appears to have evolved to both control egg development when synthesized by females2 and to induce mating refractoriness

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

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
