anaerobic fermentation的意思|示意

An anaerobic fermentation process is a process used to produce energy-rich molecules such as glucose, ethanol, or lactic acid in the absence of oxygen. This process is essential to many industrial processes because it can be used to convert renewable agricultural raw materials into products that can be used in food, chemical, and pharmaceutical production.

Anaerobic fermentation is a two-step process that can take place in either a discontinuous or continuous system. In the first step, the microorganisms break down complex macromolecules into simpler metabolites that can be used to produce energy. These metabolic pathways can be either homofermentative, in which one primary product is produced, or heterofermentative, in which several products are formed. In the second step, the metabolites are converted into energy-rich molecules.

The substrates used in anaerobic fermentation processes can range from simple sugars to complex molecules such as proteins, lipids, and carbohydrates. During fermentation, bacteria, yeasts, and other microbes break down these substrates to produce energy-rich molecules. For example, in the production of alcohols, yeasts break down carbohydrates to produce alcohols, while in the production of lactic acid, bacteria break down carbohydrates to produce lactic acid.

Anaerobic fermentation processes are essential to many industrial processes, and have been used in the production of a wide range of products including alcohols, acids, and enzymes. They are also used in the production of biodegradable plastics, biochemicals, and biofuels. In addition, anaerobic fermentation processes can be used to produce a wide range of foods, such as bread, beer, cheese, and yogurt.
