Abstract:Cyclodextrin glycosyltransferase (CGTase) degrades starch into cyclodextrin via enzymatic activity. In this study, we immobilize CGTase from Thermoanaerobacter sp. on two supports, namely graphene nanoplatelets (GNP) consisting of short stacks of graphene nanoparticles and a calcium‐based two‐dimensional metal organic framework (Ca‐TMA). The uptakes of CGTase on GNP and Ca‐TMA reached 40 and 21 mg g−1 respectively, but immobilized CGTase on Ca‐TMA showed a higher specific activity (38 U mg−1) than that on GNP … Show more
