Bacillus sp. PS304 secreted extracellular cyclodextrin glycosyltransferase (CGTase) to produce cyclodextrins (CDs) from starch. The CDs concentration was quantitated using HPLC since it was a sensitive and reliable method. The optimum conditions for production of CDs were a pH 6.5 at temperature of 50 deg C using 4 percent soluble starch from Merck. The production of alpha, beta and gamma-CDs from Bacillus sp. PS304 in a fermentor was in the ratio 1:4.7:1.2 indicating that beta-CD was the predominant product. The production of CDs was growth associated and reached a maximum at 8 hours of cultivation.
