KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen. What is Fermentation? • Cellular respiration refers to a process by which cells convert food into energy. • Fermentation is a specific chemical reaction within the respiration cycle. It takes place when the cells do not have access to oxygen, a condition also known as anaerobic respiration. • The process of fermentation generates far less energy than aerobic, or oxygen-based, respiration. Fermentation allows glycolysis to continue ...
TYPES OF FERMENTATION 1.Batch types fermentation 2.Fed batch fermentation 3.Continuous fermentation 4.Solid state fermentation 5.Anaerobic Fermentation 6.Aerobic Fermentation 2 BATCH FERMENTATION: Batch fermentation is a discontinuous process and the fermentor has to be cleaned after each process and a fresh batch started. It includes the following 5 steps: 1.Medium added 2.Fermentor sterilised 3.Inoculum added 4.Fermentation followed to completion 5.Culture harvested. 3 Characteristics of a batch fermentation system Simplest fermentor ...
Basic Principles of Food Fermentation • Introduction • Fermentation and Fermenting Microorganisms A)Food Fermentation B)Fermented Foods: An ancient Tradition C)Factors Influencing Fermentation D)Biological Agents Responsible in Food Fermentation “fermentation, far from being a lifeless phenomenon, is a living process” - Louis Pasteur The Chemistry of Fermentation - Aerobic & Anaerobic Cellular Respiration - Glycolysis - Alcoholic Fermentation - Lactic Acid Fermentation Aerobic Cellular Respiration • Aerobic means “with air”. This type of respiration needs oxygen for ...

Metabolism Anaerobic Cellular Respiration & Fermentation From the Virtual Cell Biology Classroom on ScienceProfOnline.com Everyday Biology What causes smelly farts? - Most people pass gas at least 10 – 25x a day. - Farts are mostly a byproduct microbial anaerobic respiration & fermentation in the colon (large intestine). - Over 99% of fart volume is non-smelly gases, including oxygen, nitrogen, carbon dioxide, hydrogen and methane. - Smelly farts are caused by microbes that generate volatile sulfur compounds ...
