Effect of the substrate-to-biocatalyst ratio (whole-cell biocatalyst) on product enantiopurity. Blue diamonds show the conversion of 100 mM rac-2-phenylpropanal with 4 and 10 gCDW biocatalyst, green diamonds with 1 M substrate and 40 gCDW, red diamonds with 1 M substrate and 20 gCDW, black crosses with 2 M substrate and 40 gCDW. (Data with error bars from reactions with 6 mM NAD+ are depicted. See also the section Optimization of 2-phenylpropanal bioreduction, Table 3)
