binomial name given to yeast‚ which is a fungi used in brewing‚ baking and wine making. In brewing yeast is added to the cooled wort in the fermenting vessel. The yeast is initially exposed to high oxygen levels so they can divide‚ but then conditions become anaerobic and the yeast converts the sugars to ethanol and carbon dioxide. After this the yeast is filtered out leaving beer‚ but the yeast can be reused to inoculate the next batch or sold for products such as Marmite‚ yeast extract. Cheese is another
