title: Production of cyclomaltononaose (delta-cyclodextrin) by cyclodextrin glycosyltransferases from Bacillus spp. and bacterial isolates.
abstract: The conversion of soluble starch to cyclomaltohexaose (alpha-CD), cyclomaltoheptaose (beta-CD), cyclomaltooctaose (gamma-CD) and cyclomaltononaose (delta-CD) by cyclodextrin glycosyltransferases (E.C. 2.4.1.19) from Bacillus spp. and bacterial isolates was studied. The results show that delta-CD was formed by all the enzymes investigated in the range of 5%-11.5% of the total amount of alpha-, beta-, gamma-, and delta-CD produced.
