Fig. 6From: Drug metabolite synthesis by immobilized human FMO3 and whole cell catalystsa Determination of the optimal ratio (wet cell weight) of FMO3-containing E. coli JM109 and GDH-containing E. coli BL21. Optimizing the b cell concentration (with a constant WFMO3-JM109/WGDH-BL21 ratio of 3) and investigating the effects of c citrate addition, d benzydamine concentration and e NADP+ concentration on biotransformation.
