A Effect of initial 1,6-hexanediol and adipic acid concentrations on the oxidation of 1,6-HD to AA via 6-HHA in 1 mL at 30 °C for 30 h without pH control by 3.2 mg CDW (obtained from 4 mL cell suspension) of G. oxydans 50049. B Effect of different starting concentrations of 1,6-HD and AA on the cell viability after 0, 3 and 24 h of oxidation at 30 °C for 30 h without pH control. The initial concentrations of 1,6-HD: AA in g/L were: A 0:0, B 5:0, C 10:0, D 15:0, E 20:0, F 10:10, G 10:30, and H 10:50
