Fig. 6From: Stereoselective biotransformation of racemic mandelic acid using immobilized laccase and (S)-mandelate dehydrogenaseResults of biotransformation reaction using different concentration of MA as the substrate catalyzed by the improved bi-enzymatic system after 14 h. The reaction system contained different concentration of MA, 10 mM potassium ferrocyanide, 1.0 g immobilized SMDH, 1.0 g immobilized laccase, and 50 mL Na2HPO4-citric acid buffer (200 mM, pH 6.0). Reactions were performed in triplicate, and error bars represented standard deviations (StDev)Back to article page
