Abstract

2-Ketogluconate present in a mixture with 2-ketogulonate is destroyed by fermentation with a strain of Pseudomonas fluorescens leaving desired 2-ketogulonate intact. Subsequent hydrolysis of the 2-ketogulonate yields ascorbic acid. The preferred Pseudomonas strains are NRRL B10 and ATCC 13430.
