The conversion of soluble starch to cyclomaltohexaose (α-CD), cyclomaltoheptaose (β-CD), cyclomaltooctaose (γ-CD) and cyclomaltononaose (δ-CD) by cyclodextrin glycosyltransferases (E.C. 220.127.116.11) from Bacillus spp. and bacterial isolates was studied. The results show that δ-CD was formed by all the enzymes investigated in the range of 5%–11.5% of the total amount of α-, β-, γ-, and δ-CD produced.
