Anti-Saccharomyces cerevisiae antibodies (ASCAs) are antibodies against antigens presented by the cell wall of the yeast Saccharomyces cerevisiae. These antibodies are directed against oligomannose sequences α-1,3 Man (α-1,2 Man α-1,2 Man) n (n = 1 or 2). [ 1 ]
Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times.
A killer yeast is a yeast, such as Saccharomyces cerevisiae, which is able to secrete one of a number of toxic proteins which are lethal to susceptible cells. [1] These "killer toxins" are polypeptides that kill sensitive cells of the same or related species, often functioning by creating pores in target cell membranes.
Symptoms can range from mild to extreme—often described as extreme flu-like symptoms. Many symptoms may be associated with fungemia, including pain, acute confusion, chronic fatigue, and infections. Skin infections can include persistent or non-healing wounds and lesions, sweating, itching, and unusual discharge or drainage. [citation needed]
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
Saccharomyces is a genus of fungi that includes many species of yeasts. Saccharomyces is from Greek σάκχαρον (sugar) and μύκης (fungus) and means sugar fungus.Many members of this genus are considered very important in food production where they are known as brewer's yeast, baker's yeast and sourdough starter among others.
Sic1, a protein, is a stoichiometric inhibitor [1] of Cdk1-Clb (B-type cyclins) complexes in the budding yeast Saccharomyces cerevisiae.Because B-type cyclin-Cdk1 complexes are the drivers of S-phase initiation, Sic1 prevents premature S-phase entry. [2]
The Crabtree effect, named after the English biochemist Herbert Grace Crabtree, [1] describes the phenomenon whereby the yeast, Saccharomyces cerevisiae, produces ethanol (alcohol) in aerobic conditions at high external glucose concentrations rather than producing biomass via the tricarboxylic acid (TCA) cycle, the usual process occurring aerobically in most yeasts e.g. Kluyveromyces spp. [2 ...
