Profiles of selective oxidation of D-galactose to D-galactonic acid and HMF to HMFCA using P. putida ATCC 47054 cells without (a, b) or with HMF induction (c, d). Reaction conditions: 5 mL of phosphate buffer (200 mM, pH 6.0) containing 8 gcdw/L cells, 50 g/L D-galactose, 10 g/L HMF, and CaCO3 at half molar concentration of substrate, 35 °C and 200 rpm. Error bars represented standard deviations
