Sažetak
The continuous conversion of phenylglyoxylic acid to (R)-mandelic acid was performed in an enzyme membrane reactor with simultaneous coenzyme regeneration employing mandelate dehydrogenase and formate dehydrogenase. A mathematical model of the coupled enzyme reactions was formulated and applied to determine optimal conditions for (R)-mandelic acid production. The experiments and calculations showed that the optimal operational points depend strongly on enzyme kinetics. The individual kinetic parameters determined were appropriate for the description of (R)-mandelic acid production in the simultaneous two-enzyme process. Space time yields of 700 g/(l· day) were obtained at low enzyme consumption.
