Effect of biocatalyst and 1,3PDO concentrations on specific initial oxidation rate by G. oxydnas. a Effect of biocatalyst concentration (mg/mL) on specific initial 1,3PDO (10 mg/mL) conversion rate (µg/mgCDW.min) using resting cells of G. oxydans. b Specific initial reaction rates of ADH (filled diamond) and ALDH (filled square) calculated from the data collected after 3 h during biotransformation of 1,3PDO using resting cells of G. oxydans. Asterisk indicates a significant difference between the marked data points. The data for the first substrate concentration (5 mg/ml) was ignored from Fig. 3b since the reaction was marginal after 2 h
