Cyclomaltodextrin glucanotransferase, process for its preparation and novel microorganism useful for the process.

摘要

Described is a novel cyclomaltodextrin transferase (EC. 2.4.1.19) which preferentially produces beta -cyclodextrin from starch or partial hydrolysates thereof and produces a carbohydrate mixture containing beta -cyclodextrin as the main component, and a method for its preparation which comprises cultivating a cyclomaltodextrin glucanotransferase producing microorganism belonging to the species B.coagulans.
