Industrial application of enzyme from microorganism has a history over 100 years, and for the this 40 years, there were the remarkable developments. Especially, a sweetener (isomerized sugar) produced from starch by enzymatic method was displaced to 30% of sugar consumed in Japan. In the production of the isomerized sugar, two enzymes were mainly used, which hydrolyzed starch to glucose and isomerized glucose to fructose, respectively. On the other hand, the discovery of two enzymes enabled the industrial production of trehalose from dextrin. One converted 1,4 linkage of glucose residue at reducing terminal in dextrin, to 1,1 linkage through the intramolecular transglycosylation and another released trehalose from the modified terminal. Thus various oligosaccharides and glycosides got to be industrially produced using various enzymatic transglycosylation. This review introduced the historty of enzyme developments.
