Abstract

Cyclodextrins (CDs) are maltooligosaccharides produced from starch by cyclodextrin glycosyltransferase (CGTase) enzyme. This research aimed at establishing method for strains selection for CGTase production and enzyme purification. The microorganisms were selected from 53 analyses of starch cultures soils on plates containing specific culture medium for strains selection that produce CGTase. The enzymes were obtained by culturing these microorganisms in liquid medium. The enzyme activity was determined with photospectrometric methods and precipitation with trichloroethylene. The strain isolated from oat soil was the one that showed the highest activity [0.1864 µmol of ß-CD (min mL)-1]. This strain was used for enzyme production in laboratory scale and purification by biospecific affinity chromatography. The strain selected in this research opens new perspectives for enzymes production and CDs in industrial scale.
