Title:
ENZYME FOR PRODUCING GLYOXYLIC ACID AND METHOD FOR PRODUCING GLYOXYLIC ACID BY USING THE SAME
Document Type and Number:
Japanese Patent JP2007228926
Kind Code:
A
Abstract:
To provide an oxidase or a microorganism, acting on glyoxal but not acting on glyoxylic acid, and to provide a method for efficiently producing glyoxylic acid by using low price material glyoxal.
The oxidase acting on glycolaldehyde in the presence of oxygen to produce glyoxal and hydrogen peroxide is provided, wherein, as substrate specificity, the oxidase exhibits activity to glyoxal, glycolaldehyde, formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde and isobutyraldehyde but substantially does not exhibit activity on glyoxylic acid, wherein the most suitable acting pH is 4.5-5.5 and the most suitable acting temperature is 65-75°C.
