Abstract:

For the optical resolution of R-(-)-mandelic acid from (±)-mandelic acid, Pseudomonas sp. MA02, which assimilated S-(+)-mandelic acid as carbon and energy source, was isolated from soil. Using the fed-batch culture under optimal condition, R-(-)-mandelic acid was accumulated up to the maximum theoretical yield of 50% (30 g l^−1) and entiomeric excess of 99.4%.

Keywords: fed-batch fermentation; mandelic acid; optical resolution; Pseudomonas sp.
