Effects of D-glucal on kojic acid production, glucose consumption and NOR accumulation. (A) Production of kojic acid by A. flavus grown in GMS media with or without 40 mg/mL D-glucal. Values are presented as means ± S.D. (n = 3), from three independent experiments. (B) Glucose contents in media at different time points when cultured in the presence of 40 mg/mL D-glucal. (C) D-glucal inhibited NOR accumulation. The amount of NOR in GMS medium lacking D-glucal was set to 1, those in other samples were calculated accordingly. Values are presented as means ± S.D. (n = 3).
