Effect of Temperature on Fermentation Temperature changes have profound effects upon living things. Enzyme-catalyzed reactions are especially sensitive to small changes in temperature. Because of this, the metabolism of poikilotherms, organisms whose internal body temperature is determined by their surroundings, are often determined by the surrounding temperature. Bakers who use yeast in … At the 2011 National Homebrewers Conference, Jamil Zainasheff, co-author of Yeast: The Practical Guide to Beer Fermentation and Chief Heretic at Heretic Brewing Company, gave a presentation on Growing, Harvesting, and Pitching Yeast. The rate of alcoholic fermentation in yeasts can be measured by collecting the amount of carbon dioxide given off during fermentation. Factors such as temperature, pH, carbon and nitrogen sources, oxygen and water availability, can affect the rate of yeast fermentation. Introduction Yeasts are unicellular microorganisms that are classified in the Kingdom Fungi. In the absence of oxygen, yeast[…]
