Research output: Contribution to conferencePaperpeer-review


Ultrasonic irradiation onto starch-glycolipid mixture solution, which induced the proximity effect between glycosyl donor and acceptor, enhanced a transglycosylation reaction activity of α-amylase having low transglycosylation efficiency. The transglycosylation efficiency strongly depended on the reaction temperature and the initial soluble starch concentration, because these reaction conditions affected the proximity effect and transglycosylating/hydrolyzing activity ratio of this reaction system.
