Yeast is the colloquial name for members of the fungal families, ascomycetes, basidiomycetes and imperfect fungi, that tend to be unicellular for the greater part of their life cycle. Commercially important yeasts include Saccharomyces cerevisiae ; pathogenic yeasts include the genus Candida . See also Schizosaccharomyces pombe > Schizosaccharomyces pombe.
A unicellular ascomycete that multiplies typically by a budding process.
One-celled fungi that reproduce by budding. Some ferment carbohydrates (starches and sugars), important for baking and brewing. Many biochemical properties of yeast are similar to those of higher organisms.

A handy microorganism, without which we wouldn't have bread, beer or wine. Yeasts eat the sugar in grape juice and excrete alcohol and carbon dioxide as waste products. They keep going until all the sugar is gone, or until the alcohol level reaches about 16%, at which point they die. The selection of the appropriate yeast strain -- or indeed the de...Found on http://www.encyclo.co.uk/local/20433
Yeast are micro-organisms, which activate the fermentation process, converting the malt sugars into alcohol and carbon dioxide. Most breweries raise their own strains of yeast to guarantee the consistency of their beers.

Yeast: A group of single-celled fungi that reproduce by budding. Most yeast are harmless (some are used in baking and brewing). Yeast is commonly present on normal human skin and in areas of moisture, such as the mouth and vagina, usually without causing any problems. However, yeast can produce disease in people. For example, the yeast Candida (onc...Found on http://www.medterms.com/script/main/art.asp?articlekey=6051
