What Is Fermentation? 1.发酵(ferme: To many people,fermentation simply means the produc- tion of alcohol.Grains and fruits are fermented to pro- duce beer and wine.If a food soured,you might say it was "off"or fermented.Here are some definitions of fer- 有机物氧化 mentation.They range from informal,general usage to more scientific definitions.Fermentation is: 氧化的某种中 1.Any process that produces alcoholic beverages or acidic dairy products(general use). 种不同的代诲 2.Any spoilage of food by microorganisms (general use). 3.Any large-scale microbial process occurring with or without air(common definition used in industry). 4.Any energy-releasing metabolic process that takes place only under anaerobic conditions(becoming more scientific). 5.All metabolic processes that release energy from a sugar or other organic molecule,do not require oxygen or an electron transport system,and use an organic molecule as the final electron acceptor. This is the definition we will use in this book
