Medical term:

Yeast

yeast

[yēst]

any of various unicellular, nucleated, usually rounded fungi that reproduce by budding; some are fermenters of carbohydrates, and a few are pathogenic for humans.

brewer's yeast Saccharomyces cerevisiae, used in brewing beer, making alcoholic liquors, and baking bread.

dried yeast dried cells of any suitable strain of Saccharomyces cerevisiae, usually a by-product of the brewing industry; used as a natural source of protein and B-complex vitamins.

yeast

(yēst),

A general term denoting true fungi of the family Saccharomycetaceae that are widely distributed in substrates that contain sugars (such as fruits), and in soil, animal excreta, the vegetative parts of plants, etc. Because of their ability to ferment carbohydrates, some yeasts are important to the brewing and baking industries.

yeast

(yēst)

a. Any of various unicellular fungi of the genus Saccharomyces, especially S. cerevisiae, reproducing asexually by budding or sexually through the production of ascospores and capable of fermenting carbohydrates.

b. Any of numerous fungi that exhibit a one-celled growth form and reproduce by budding, including certain candidas that can cause infections in humans.

2. Froth consisting of yeast cells together with the carbon dioxide they produce in the process of fermentation, present in or added to fruit juices and other substances in the production of alcoholic beverages.

3. A powdered or compressed commercial preparation of yeast cells, used chiefly as a leavening agent or as a dietary supplement.

yeast

A unicellular spherical-to-oval 3–5 µm budding fungus that reproduces both sexually and asexually, primarily by budding–some by binary fission which, when adherent in end-to-end rows are termed pseudohyphae; most fungi are saprobes; many are used in commercial fermentation of foods and beverages; 7 genera–class Deuteromycetes–Imperfect Fungi–are human pathogens: Candida, Crytococcus, Geotrichum, Pityrosporum, Rhodotorula, Torulopsis, Trichosporon. See Candida, YAC cloning.

BUDDING YEAST: (×400)

1. Any of several unicellular fungi of the genera Saccharomyces or Candida, which reproduce by budding. They are capable of fermenting carbohydrates. Yeasts, esp. Candida albicans, may cause systemic infections as well as vaginitis and oral thrush. Yeast infections are frequently present in patients with malignant lymphomas, poorly controlled diabetes mellitus, AIDS, or other conditions causing immunocompromise. Synonym: Saccharomyces See: illustration; Candida; candidiasis; fungi

2. A commercial product composed of meal impregnated with living fungi, used, for example, in fermenting beer and ale and baking bread.

brewer's yeast

Yeast obtained during the brewing of beer. It is a rich source of folic acid and chromium.

dried yeast

Dried yeast cells from strains of Saccharomyces cerevisiae. It is used as a source of proteins and vitamins, esp. B complex.

yeast

a collective name for those unicellular fungi, typically in the ASCOMYCOTA, of economic importance in the brewing and bread-making industries (see SACCHAROMYCES). Yeasts secrete ENZYMES that convert sugars into alcohol and carbon dioxide (see ALCOHOLIC FERMENTATION) and it is the CO₂ which causes bread to ‘rise’.
