Biofermentation is a process that utilizes the metabolic activities of microorganisms to convert raw materials into products desired by humans. As the core technology of fermentation engineering, biofermentation system is widely used in food, medicine, agriculture, environmental protection and other fields. In this paper, we will introduce the principle, application and its development trend of biofermentation system in detail.

Principles of biofermentation systems

1. Definition of fermentation

Fermentation is a biochemical process by which microorganisms metabolize organic substances under anaerobic or microaerobic conditions to produce energy, grow and reproduce, and produce metabolites.

2. Composition of a biofermentation system

The biofermentation system consists of the following main components Components:

(1) Fermenter: It is the main equipment of the fermentation process and is used to provide suitable conditions such as temperature, humidity and oxygen.

(2) Strain: the core of the fermentation process, different strains have different metabolic pathways and products.

(3) Medium: provides microorganisms with nutrients needed for growth, including carbon sources, nitrogen sources, vitamins, minerals and so on.

(4) Control system: used to monitor and regulate the temperature, humidity, oxygen, pH and other parameters in the fermentation process.

3. Key factors of fermentation process

(1) Bacteria strains: choosing the right bacteria strains is the fermentation The key to the success of fermentation.

(2) Medium: optimize the medium formula to meet the growth requirements of microorganisms.

(3) Fermentation conditions: control the appropriate fermentation temperature, humidity, oxygen, pH, etc..

(4) Fermentation time: Determine the appropriate fermentation time according to the characteristics of the strain and the law of product generation.

Applications of Bio-fermentation Systems

1. Foods Fermentation

Food fermentation is an important application of biofermentation systems in the food industry, such as soy sauce, vinegar, bean curd milk and yogurt. Fermented foods have rich nutritional value, unique flavor and health care functions.

2. Pharmaceutical fermentation

Pharmaceutical fermentation is Biofermentation systems are used in the field of pharmaceuticals, such as antibiotics, vaccines, hormones, and so on. Fermented drugs are characterized by good efficacy and low side effects.

3. Agricultural fermentation

Agricultural fermentation is mainly used to produce microbial fertilizers, pesticides, feed, etc. Microbial fertilizers can improve soil fertility and promote crop growth; microbial pesticides are environmentally friendly and efficient.

4. Environmental protection

Biological fermentation system It is widely used in the field of environmental protection, such as wastewater treatment, exhaust gas treatment and solid waste treatment. Microorganisms can decompose organic substances and reduce the concentration of pollutants during the fermentation process.

Trends in biofermentation systems
