ABSTRACT:
An improved process for preparing glyoxylic acid comprising using the enzyme glycolate oxidase in the form of permeabilized microbial cell transformants selected from Aspergillus nidulans, Hansenula polymorpha, Pichia pastoris and Escherichia coli to oxidize glycolic acid with oxygen in an aqueous solution that includes an amine.
