The profile of 2-HPP production by the encapsulated P. putida. A: 2-HPP production by a benzaldehyde concentration of 20 mM and with 0.033 g WCW/mL of immobilized cells load. B: 2-HPP production by a benzaldehyde concentration of 40 mM and with 0.033 g WCW/mL of immobilized cells load. C: 2-HPP production by a benzaldehyde concentration of 20 mM and with 0.055 g WCW/mL of immobilized cells load. Biotransformation was carried out aerobically with a constant acetaldehyde concentration of 600mM, 200 beads in 6 mL buffer at 30 ^°C and pH 7 with shaking at 200 rpm. Data are results of triplicate experiments ± SD
