Enzyme Engineering

In short, enzyme engineering is to the enzyme or microbial cells, animal and plant cells, organelles, etc in a certain biological reaction device, this enzyme has the function of biological catalysis, engineering means the corresponding materials into useful material and used in the social life of a science technology. It includes the preparation of enzyme preparation, enzyme immobilization, enzyme modified and retrofit and enzyme reactor in terms. The application of enzyme engineering, mainly in the food industry, light industry and pharmaceutical industry.
Main application
As a kind of biological enzyme catalysts, has been widely applied to the production field all light industry. In recent decades, with enzyme engineering technical breakthrough, constantly in industry, agriculture, medicine and health, energy development and environmental engineering, the application of more and more widely.
-food processing applications
Enzyme in the food industry is the biggest use of starch processing, the second is dairy processing, juice processing, baking food and beer fermentation. In connection with the various enzymes such as amylase, glucose heterogeneous enzyme, lactose enzyme, curd enzyme, protease of enzyme preparation, more than half of the market.
At present, the help and promote the enzyme digestion become the main development direction of food markets, including promotes protein digestion enzyme (pineapple proteinase, pepsin, trypsin, etc.), promote digest cellulose enzyme (cellulose enzyme, xylanolytic enzymes, etc), promote digest lactose enzyme (lactose digestion enzyme) and promote adipose the enzyme (lipase, ester enzyme), etc.
Second, the application of light industry
In light of the enzyme engineering industry USES include: detergent manufacturing (enhancement to scale ability), fur industry, gelatin manufacturing, and collagen fiber manufacturing (adhesive) toothpaste and cosmetics production, papermaking, photographic materials production, waste water waste treatment and feed processing, etc.
The application of the three, medicine
Recombinant DNA technology to promote the of all kinds of medical value of the enzyme mass production. Used for clinical of all kinds of enzyme varieties increase gradually. In addition to the routine treatment used for the enzyme, can also be used as some part of medical engineering and medical role play. As in extracorporeal circulation device, with enzymes remove waste, prevent blood clots formed in the body and enzyme drug release system etc. Control In addition, as the clinical testing reagents in vitro enzyme, can quickly, sensitive and accurate determination of some metabolic product in the body, will also is in the medical enzyme an important applications.
Four, the application of energy development
In the world of new type energy development trend, using microorganism or enzyme engineering technology from the biology of the production is people are seeking fuel a new road. For example, the use of plants, crops, forest products the cellulose of waste, hemicellulose, and lignin substances, starch, producing hydrogen, raw materials such as methane gas, such as fuel and ethanol and methanol liquid fuel. In addition, in the development of petroleum resources, as the microorganism oil exploration, secondary oil, petroleum refining means at home and abroad in recent years is also of common concern to the subject.
Five, the environment of engineering application
In the science and technology of the high development of the at the same time, environmental purification, especially industrial wastewater and sewage purification, as a measure of the protection of nature, have very important sense.
In the existing wastewater cleaning method, biological purify is often the most feasible and lowest cost. Microbial metabolism process, can use some of the material as organic wastewater required source of nutrients. So the microorganism in the body of the enzyme function, and can be the organic wastewater to material into the use of small molecules, and achieve the purpose of purifying the wastewater. People use genetic engineering technology to create efficient strains, and use the immobilized microorganism cells and other methods, live in wastewater treatment and environmental protection work made remarkable results.
In addition, the emergence of biological sensors for environmental monitoring the continuous and automation provides, and to reduce the environmental monitoring may be the cost of the environment, to strengthen the supervision of strength.
