What does fermentation mean?

Pinyin: Fā Jiào

English: ferment; zymolysis; zymosis; leaven

Broadly speaking, fermentation refers to the process of biochemical reactions that utilize the metabolic functions of living organisms (including microorganisms, plant cells, and yeasts) to break down organic matter.

For example, brewing wine, making vinegar, fermenting dough, generating biogas, and rotting garbage ......

Narrow concept of fermentation: the process by which microorganisms convert sugars into ethanol through anaerobic oxidation.

Fermentation is divided into aerobic and anaerobic (anaerobic) fermentation.

For example, wine is fermented under anaerobic conditions, while vinegar is fermented under aerobic conditions.

Fermentation engineering is to give microorganisms the most suitable conditions for growth, the use of microbial metabolic functions, through modern technology to produce products needed by mankind. Some people also call it microbial engineering. To put it simply, it is a purposeful fermentation production process for humans.
