∙ 9y agoYeast requires carbohydrates such as sugar and starch to grow. The sugar or starch produces carbon dioxide (C02), alcohol and gas. Yeast is responsible for rising of bread dough, and fermentation of some Alcoholic Beverages. Yeast also play a role in vinegar making.
Depending on its use, temperature can effect yeast growth. Some uses, such as fermentation of wines and beer often require a temperature of 7 degrees celsius, whereas the ideal temperature of the water to activate yeast for bread making is around 100 degrees F.
Sugar, salt, starch, light, and temperature all have an effect on the growth of yeast.
