Abstract

Simultaneous liquefaction and cyclodextrin (CD) production were conducted on potato starch using cyclomaltodextrin glucanotransferase (CGTase) from a mutant strain MNNG 8 of Bacillus stearothermophilus No. 239. A high concentration (30%) of potato starch was converted to cyc1o-dextrins (CDs) with 29% yield in the conditions of pH 6.0, temperature $80^{\circ}C$, 4.3 mM $CaCl_2$, CGTase addition of 3.0 dextrinizing activity unit (DAU) at $40^{\circ}C$/g starch.
