outside it was a lot of research. Representative of the domestic units: Sichuan University, major research production of αamylase strains and culture conditions。 Jiangnan University, the main research structure of αamylase and application performance, such as heat resistance, acid resistance。 Northwest universities, major research denatured αamylase and the environment on the mechanism of αamylase。 South China University of Technology, the main αamylase of immobilization and dynamic nature。 there Huazhong Agricultural University, Chinese Academy of Sciences Institute of Applied Ecology in Shenyang, Tianjin University, Nankai University, College of Life Sciences, Chinese Academy of Agricultural Sciences, Chinese Academy of Sciences Institute of Microbiology and a number of research institutions on a variety of bacterial αamylase production of a amylase gene cloning and expression. Representative of foreign research units are: Canada UniversityofBritishColumbia, they were a pancreatic amylase structure and mechanism of indepth research。 Denmark39。s Carlsberg Research Laboratory of the main structure of barley αamylase domain and binding sites。 . WesternRegionalResearchCenter major study αamylase in barley and the role of antibiotics and the barley αamylase active site. 3, αamylase conclusion has bee the industrial application of one of the most important enzymes, and a large number of microanisms can be used for efficient production of amylase, but largescale mercial production of the enzyme is still limited to some specific fungi and bacteria. For the effective demand for αamylase more and more, this enzyme by chemical modification of existing or improved technology through the white matter are. Benefit from the development of modern biotechnology, α an amylase in the pharmaceutical aspects of growing importance. Of course, the food and starch industries is still the main market, α amylase in these areas, a demand is still the largest. Journal of Southeast University(English Edition)2020 24( 4)
