Whole Cell Bioconversion of Ricinoleic Acid to 12-Ketooleic Acid by Recombinant Corynebacterium glutamicum-Based Biocatalyst.

The biocatalytic efficiency of recombinant Corynebacterium glutamicum ATCC 13032 expressing the secondary alcohol dehydrogenase of Micrococcus luteus NCTC2665 was studied. Recombinant C. glutamicum converts ricinoleic acid to a product, identified by gas chromatography/mass spectrometry as 12-ketooleic acid (12-oxo-cis-9-octadecenoic acid).
