Fermentation technology is one of the earliest biotechnologies mastered by mankind, with a long history and wide application. Fermentation system refers to a set of equipment and technology system used for microbial fermentation production, which includes fermenter, control system, medium preparation, product extraction and purification. With the progress of science and technology, fermentation system plays an increasingly important role in the fields of food, medicine, biochemicals and so on. In this article, we will discuss the principle, technical points, development trend and practical application of fermentation system, and bring you to enjoy the charm of this traditional process and modern technology integration.

Basic principle of fermentation system

Definition of fermentation: Fermentation is the process of utilizing the organic matter by microorganisms under the condition of anoxic or microoxic. or microaerobic conditions, utilizing organic matter for growth and reproduction, and producing target metabolites.

FERMENTATION PROCESS: The fermentation process mainly includes the steps of strain screening and cultivation, fermentation condition control, product extraction and purification.

Technical points of the fermentation system

Strain selection and breeding: excellent strains are the key to successful fermentation. Through mutation breeding, genetic engineering and other methods, new strains with high yield, stability and adaptability are screened.

Medium optimization: Reasonable configuration of the composition of the medium, to provide sufficient nutrients for microorganisms, is conducive to improving the fermentation yield and product quality.

Fermentation conditions control: including temperature, pH, dissolved oxygen, stirring speed, replenishment strategy, etc., to achieve the best fermentation results.

Fermenter design: the design of the fermenter should meet the needs of microbial growth and metabolism, and ensure the efficiency of mass and heat transfer.

The development trend of fermentation system

Automation and Intelligence: the fermentation process is gradually realizing the automation control, real-time monitoring and adjustment of fermentation conditions through the computer system, and improving the production efficiency.

Integration: fermentation, separation, purification and other links are integrated in one system, simplifying the process and reducing production costs.

Scale and continuity: with the increase of market demand, the fermentation system to scale and continuity to improve production.

Green: the fermentation system pays more attention to environmental protection in the utilization of raw materials and energy, and reduces waste emissions.

Practical application of fermentation system

Food industry: Fermentation technology has a wide range of applications in the production of traditional foodstuffs, such as soy sauce, vinegar, yoghurt, and beer.

Pharmaceutical manufacturing: fermentation technology is indispensable for the production of antibiotics, vitamins, hormones and other biological drugs.

Biochemicals: fermentation systems are increasingly used in the fields of biopesticides, biofuels, and bioplastics.

Environmental protection: Fermentation technology can be used to treat organic wastewater and waste gas, and to realize pollutant degradation and resource recovery.

Fermentation system, as an important part of biotechnology, has a bright future. With the continuous progress of science and technology, fermentation system will play an important role in more fields and contribute to the sustainable development of human society. In the face of challenges, China's fermentation industry should increase research and development efforts to promote the development of fermentation technology to a higher level, and to realize the perfect integration of traditional technology and modern technology.
