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

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

In this paper, the production of a second-generation bioethanol from lignocellulosic vineyard cutting wastes was investigated in order to define the optimal operating conditions of the autohydrolysis pretreatment, chlorite delignification and simultaneous saccharification and fermentation (SSF). The autohydrolysis of vine-shoot
