Whole-cell biocatalyst-mediated synthesis of troxerutin propionyl derivatives: a catalytic performances of P. aeruginosa cells (left of dotted line) and P. stutzeri cells (right of dotted line), b effect of molar ratio of VP/troxerutin on the catalytic activity of P. aeruginosa after reacting for 7 h, and c effect of reaction time on the catalytic activity of P. aeruginosa when the molar ratio of VP/troxerutin was 30 after reacting for 120 h. Experiments were performed in triplicate, and data are presented as the mean ± SD
