Method for preparing 2,5-diketo-D-gluconic acid

摘要

2,5-Diketo-D-gluconic acid is prepared in high yield and in high broth concentration by cultivating newly isolated microorganisms of genus Erwinia in an aqueous nutrient medium in the presence of D-glucose. The production is also possibly by simple contact of said microorganisms or their processed products therefrom, with D-glucose.
