Yeast - Life Cycle, The Importance Of Yeast For Humans, Biotechnology And Yeast
celled fungi single
Yeasts are single-celled fungi, belonging mainly to the Ascomycetes, that serve as nutrient recyclers in nature, but are also important in industry, biotechnology, and as the agents of disease in humans. The term yeast is generically used in reference to many species of single-celled, budding fungi, including Saccharomyces—used in baking and brewing—and Candida—an infectious yeast common in people with compromised immune systems, such as AIDS victims.

Yeasts secrete enzymes that break down carbohydrates (through fermentation) to yield carbon dioxide and alcohol. The source of carbohydrates are either living hosts or non-living hosts such as rotting vegetation, or the moist body cavities of animals. Yeasts are considered by some scientists to be closely related to the algae, lacking only in photosynthetic capability—perhaps as a result of…
People have been using yeast in bread baking for centuries, but suffering from its scourges for much longer. The biochemical by-products of yeast sugar metabolism—carbon dioxide and alcohol—are essential in baking and brewing. Bakers yeast (Saccharomyces cerevisiae), when added to baker's dough, produces carbon dioxide pockets that make bread rise. Brewer's yeast, anoth…
Yeasts are rising stars in the toolbox of biotechnologists. Early in the development of biotechnology, which used cells as recipients of transplanted genes, bacteria were the organism of choice. However, limitations involving differences between bacterial cells and our own have relegated bacteria to a second place behind yeasts. Both yeast cells and human cells are eukaryotic—possessing a n…
