Including preparation of enzyme preparations, immobilization of enzymes, modification and transformation of enzymes and enzyme reactors, etc.
Application:
As a kind of biological catalyst, enzymes have been widely used in various production fields of light industry. In recent decades, with the continuous technological breakthroughs of enzyme engineering, it has become more and more widely used in industry, agriculture, medicine and health, energy development and environmental engineering.
applications in food processing
The largest use of enzymes in the food industry is starch processing, followed by dairy processing, fruit juice processing, bakery and beer fermentation. Various related enzymes such as amylase, glucose isomerase, lactase, rennet, protease, etc. account for more than half of the enzyme preparation market.
Enzymes that help and promote food digestion have become the main direction of food market development, including enzymes that promote protein digestion (bromelain, pepsin, trypsin, etc.), enzymes that promote cellulose digestion (cellulase, glycanase, etc.), Enzymes that promote the digestion of lactose (lactase) and enzymes that promote the digestion of fats (lipase, esterase), etc.
Application in Light Industry
The uses of enzyme engineering in the light chemical industry mainly include: detergent manufacturing (enhancing detergency), fur industry, gelatin manufacturing, collagen fiber manufacturing (adhesive), toothpaste and cosmetic production, papermaking, photosensitive material production, wastewater waste Handling and feed processing, etc.
medical applications
Recombinant DNA technology has facilitated the large-scale production of various medically valuable enzymes. Various types of enzymes for clinical use are gradually increasing. In addition to being used as conventional treatments, enzymes can also play a medical role as some components of medical engineering. For example, in extracorporeal circulation devices, enzymes are used to remove blood waste, prevent thrombosis, and in vivo enzyme-controlled drug release systems. In addition, as a clinical in vitro detection reagent, enzymes can quickly, sensitively and accurately determine certain metabolites in the body, and will also be an important application of enzymes in medical care.
energy development
Under the general trend of developing new energy sources all over the world, the use of microbial or enzyme engineering technology to produce fuels from living organisms is also a new way that people are exploring. For example, using raw materials such as cellulose, hemicellulose, lignin, starch, etc. in plants, crops, and forestry product wastes to produce gaseous fuels such as hydrogen and methane, and liquid fuels such as ethanol and methanol. In addition, in the development of petroleum resources, the problem.
Environmental Engineering
With the high development of science and technology, environmental purification, especially the purification of industrial wastewater and domestic sewage, is of great significance as a measure to protect nature.
Enzyme engineered food
Among existing wastewater purification methods, biological purification is often the lowest cost and most feasible. The metabolic process of microorganisms can utilize certain organic substances in wastewater as a required source of nutrients. Therefore, by using the action of enzymes in microorganisms, organic substances in wastewater can be converted into usable small molecular substances, and the purpose of purifying wastewater can be achieved at the same time. People use genetic engineering technology to create high-efficiency strains, and use methods such as immobilizing live microbial cells, and have achieved remarkable results in wastewater treatment and environmental protection.
