Answers:
Yeast are simple, unicellular fungi. The most common forms of yeast -- baker's and brewer's yeast -- are strains of the species Saccaromyces cerevisiae. Yeast is often taken as a vitamin supplement because it is 50 percent protein and is a rich source of B vitamins, niacin, and folic acid.
Yeast microbes are probably one of the earliest domesticated organisms. People have used yeast for fermentation and baking throughout history. Archaeologists digging in Egyptian ruins found early grinding stones and baking chambers for yeasted bread, as well as drawings of 4,000-year-old bakeries and breweries. Only in the last 150 years, since the experiments of Louis Pasteur, have scientist begun to explore how yeast works. Pasteur first proposed the production of carbon dioxide from yeast as responsible for raising a loaf of bread in 1859.
