MindMap Gallery Fermentation engineering and its applications
This is a mind map about fermentation engineering and its applications. Fermentation engineering is a new technology that utilizes the specific functions of microorganisms to produce products useful to humans, or directly applies microorganisms to industrial production processes.

Fermentation engineering and its applications
1. Basic links of fermentation engineering

common problem
(1) Why does it need to be "ventilated first and then sealed" during the yeast alcohol fermentation process? The purpose of "aeration" is to allow yeast to carry out aerobic respiration and multiply; The purpose of "sealing" is to allow yeast to undergo alcoholic fermentation to produce alcohol. (2) In beer production, fermentation is an important step. In the later stage of fermentation, if the sealing is not tight, the beer will become sour. Do you know what has changed? Alcohol is oxidized under the action of acetic acid bacteria to produce acetaldehyde, which eventually becomes acetic acid.

2. Application of fermentation process
food industry
Produce traditional fermented products, such as soy sauce, various wines, etc.
Example 1: Producing soy sauce
Soybean → Aspergillus niger → Protein hydrolyzed into small molecule peptides and amino acids → Elution and preparation → Soy sauce
Example 2: Brewing
Cereals or fruits → Saccharomyces cerevisiae → Alcoholic beverages
Produces a wide range of food additives
Production of enzyme preparations
Pharmaceutical industry
Drugs produced by fermentation engineering
Antibiotics, amino acids, hormones, immunomodulators
Combining genetic engineering, protein engineering and fermentation engineering
Agriculture and animal husbandry
Produce microbial fertilizers
Utilize the organic acids and bioactive substances produced by microorganisms during the metabolic process to increase soil fertility, improve soil structure, promote plant growth, and enhance plant disease resistance and stress resistance.
Common microbial fertilizers
Rhizobium fertilizer, nitrogen-fixing bacteria fertilizer
Production of microbial pesticides
Using microorganisms or their metabolites to control pests and diseases
Common microbial pesticides
Producing microbial feed
Single-cell protein: A large number of microbial cells obtained through fermentation using hydrolysates of starch or cellulose, sugar industry waste, etc. as raw materials. Obtained by filtration, precipitation, etc.
Adding lactic acid bacteria to silage can improve the quality of the feed, keep the feed fresh, and improve the immunity of animals after eating it.
Other applications
Solve resource shortage and environmental pollution problems
Utilizing fiber waste fermentation to produce alcohol, ethylene and other energy substances
Utilization of extremophiles (living in high temperature, high pressure, high salt and low temperature environments)
Utilizing thermophilic and halophilic bacteria to produce detergents
