Abstract
A process for the production of cyclodextrins, comprising reacting non-treated starch with cyclodextrin-glycosyl-transferase produced by Bacillus ohbensis (FERM BP-3180), or produced by a mutant derived from Bacillus ohbensis (e.g., FERM BP-3180), or produced by any other strain in which the CGTase gene from B. ohbensis has been cloned, in an aqueous solution at pH between 6.5 and 8.8 and extracting the cyclodextrins from the reaction mixture by ultrafiltration, is provided.
