yeast, any of about 1,500 species of single-celled fungi, most of which are in the phylum Ascomycota, only a few being Basidiomycota. Yeasts are found worldwide in soils and on plant surfaces and are especially abundant in sugary mediums such as flower nectar and fruits. There are hundreds of economically important varieties of ascomycete yeasts; t...
As fungi, yeasts are eukaryotic organisms. They typically are about 0.075 mm (0.003 inch) in diameter and have many forms, from spherical to egg-shaped to filamentous. Most yeasts reproduce asexually by budding: a small bump protrudes from a parent cell, enlarges, matures, and detaches. A few yeasts reproduce by fission, the parent cell dividing in...
In food manufacture, yeast is used to cause fermentation and leavening. The fungi feed on sugars, producing alcohol (ethanol) and carbon dioxide; in beer and wine manufacture the former is the desired product, in baking it is the latter. In sparkling wines and beer some of the carbon dioxide is retained in the finished beverage. The alcohol produced in bread making is driven off when the dough is baked. The fermentation of wine and sourdough breads is often initiated by naturally occurring yeasts present in air. One yeast cell can ferment approximately its own weight of glucose per hour.
In commercial production, selected strains of yeast are fed a solution of molasses, mineral salts, and ammonia. When growth ceases, the yeast is separated from the nutrient solution, washed, and packaged. Yeast for baking is sold in compressed cakes containing starch or in a dry granular form mixed with cornmeal.

Biofilm, or bacterial aggregates, are microorganisms embedded in a thick, slimly barrier of sugars and proteins. This barrier shields microorganisms from a patient’s natural immune system and from many antimicrobial agents. 1 Biofilm can form in a wound within 24 hours.
Flor (Spanish and Portuguese for flower) in winemaking, is a film of yeast on the surface of wine, important in the manufacture of some styles of sherry. The flor is formed naturally under certain winemaking conditions, from indigenous yeasts found in the region of Andalucía in southern Spain.
