Microbial Fermentation Services

Microbial fermentation refers to the use of microorganisms, under suitable conditions, the raw materials through a specific metabolic pathway into the products needed by human beings. The production level of microbial fermentation mainly depends on the genetic characteristics and culture conditions of the strain itself. According to the requirements of fermentation conditions, microbial fermentation process can be divided into aerobic fermentation and anaerobic fermentation. Aerobic fermentation methods include liquid surface culture fermentation, porous or granular solid medium surface fermentation and aerobic submerged fermentation. The submerged fermentation with no oxygen was used in the anaerobic fermentation. Therefore, both aerobic and anaerobic fermentation can be realized by deep culture, which is completed in a cylindrical fermentor with a certain ratio of diameter to height.

Application of Microbial Fermentation

Fermentation engineering has the characteristics of mild production conditions, rich sources of raw materials and low price, specific products, low environmental pollution and easy disposal of waste. It has been widely used in pharmaceutical industry, food industry, agriculture, metallurgy industry, environmental protection and many other fields, and gradually formed a large-scale fermentation industry. As far as the application of fermentation engineering in pharmaceutical industry is concerned, it has achieved remarkable results, such as antibiotics, vitamins, animal hormones, medicinal amino acids, nucleotides (such as inosine) and so on. At present, there are more than 100 kinds of antibiotics, such as penicillins, cephalosporins, erythromycin and tetracyclines. In addition, a large number of genetic engineering drugs produced by fermentation engineering, such as human growth hormone, recombinant hepatitis B vaccine, some kinds of monoclonal antibodies, IL-2, anti-hemophilia factor and so on.
