EVALUATION OF KLUYVEROMYCES-MARXIANUS FOR THE PRODUCTION OF LACTASE SIMULTANEOUSLY TO PECTINASE OR INULINASE

Five strains of K. marxianus were evaluated for the production of intracellular lactase, intra and extracellular pectinase and intra and extracellular inulinase. The strain NRRL-Y-1109 showed the highest lactase activity, but the strain CDBB-L-278 produced notably higher activities of inulinase and pectinase than the rest of the strains tested. The strain CDBB-L-278 was selected for the simultaneous production of two enzymes. Two enzymes fermentations were achieved with productions of 44% lactase and 53% pectinase, or 26% lactase and 47% inulinase compared to the single enzyme levels.
