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.

Um processo melhorado para preparar o ácido glyoxylic que compreende usando o oxidase do glycolate do enzyme no formulário de permeabilized os transformants microbial da pilha selecionados dos nidulans do aspergilo, do polymorpha de Hansenula, dos pastoris de Pichia e dos escherichia coli para oxidar o ácido glycolic com oxigênio em uma solução aqueous que incluísse um amine.
