Abstract
A novel enzyme choline oxidase is produced by culturing a microorganism belonging to the genus Arthrobacter, and particularly the species Arthrobacter globiformis B-0577 FERM-P No. 3518, NRRL B-11097, and isolating the choline oxidase thus produced from the culture medium. Choline oxidase is useful for the determination of choline or betaine aldehyde in a sample by mixing the new product with the sample and then measuring the generated hydrogen peroxide, betaine or consumed oxygen.
