Figure 5From: Rationally re-designed mutation of NAD-independent l-lactate dehydrogenase: high optical resolution of racemic mandelic acid by the engineered Escherichia coliTime course of the kinetic resolution of racemic mandelic acid by whole cells of E. coli expressing V108A l -iLDH. (♦) l-mandelic acid; (▪) d-mandelic acid; (□) benzoylformic acid. Accurate concentrations of benzoylformic acid and mandelic acid in the reaction mixture were analyzed by HPLC at the indicated times. Values are the mean ± SD of 3 separate determinations.Back to article page
