uses of yeast in science

The yeast Saccharomyces cerevisiae is a model organism widely used to study cell biological processes because of its easy genomic manipulation and its close relatedness to higher eukaryotes. It's different from the active dry yeast you use in baking because it doesn't foam or froth. The scientific name for the yeast that baker’s use is Saccharomyces Cerevisiae, or “sugar-eating fungus”. A very long name for such a tiny organism! It is one of the simplest eukaryotic (consists of cells that contain a nucleus) organisms. Because it's inactive, it can't cause dough or bread to ferment or rise. The carbon dioxide gas makes the dough rise. Yeast works best in a warm, moist environment, which is why it’s best to … Key facts. Yeast is also incredibly flexible. Yeast can be used in the process of brewing beer, to ferment the mixture and make it alcoholic. Yeast converts sugar and starch ( from the sugar and flour in the bread mix ) into carbon dioxide and ethanol. Yeast is a living single celled organism commonly used in baking. Yeast are placed in huge vats of corn or other organic material. It is commonly used in the bread-making industry. Saccharomyces cerevisiae is a type of yeast, a single-celled organism. Yeast is a type of leavener ( baking soda and baking powder can also be used as leaveners ). (Along with the additional flavors of hops, that can vary the tastes of different types of beer.) There are thousands of different species and strains, each with its own genetic makeup. When fermentation takes place, the yeast convert the organic material into ethanol fuel. For electron microscopy, the good freezing properties and the small size of yeast cells make it a nearly ideal specimen for the development of cryopreparation techniques. This species of yeast is very strong and capable of fermentation, the process that causes bread dough to rise. In recent times, yeast have been used to aid in the production of alternative energy sources that do not produce toxic chemicals as byproducts. When baked, the live yeast dies, but the air bubbles are kept, and give bread and other baked goods their soft, spongy texture.
