Abstract

Novozyme 435 (commercially immobilized lipase B from Candida antarctica) was found to catalyze the intramolecular Cannizzaro reaction of phenylglyoxal in aqueous medium forming mandelic acid. Simultaneously, the oxidation of phenylglyoxal to phenylglyoxylic acid was also found to take place. For optimization of conversion of each of these products, different enzymes were tried as the biocatalyst. The presence of various organic co-solvents was also found to have a marked effect of the course of the reaction.
