Abstract
Ethanolamine in a sample can be assayed by treating the sample with ethanolamine oxidase, thereby to catalyze a reaction-consuming ethanolamine, oxygen and water, and forming glycolaldehyde, ammonia and hydrogen peroxide. The amount of consumed oxygen or the amount of generated ammonia or hydrogen peroxide is then determined, as a measure of the ethanolamine that was originally the sample. The ethanolamine can appear in the sample as such, or can be liberated simultaneously with or prior to the catalysis reaction, from an ethanolamine derivative, e.g. phosphatidyl ethanolamine by the action of phospholipase D. Ethanolamine oxidase can be produced from Bacillus sp. B-0783 FERM-P No. 5798 in a conventional culture medium, preferably by submerged aeration liquid culturation.
