Effects of D-glucal and D-galactal on AF production and sporulation. (A) Amounts (μg per mL media) of AFB1 produced by A. flavus with different concentrations of D-glucose, D-glucal, or D-galactal (0, 2.5, 5, 10, 20 or 40 mg/mL). Data are presented as means ± S.D. (n = 3), from 3 independent experiments. (B) TLC analyses of AF production by A. flavus cultured in GMS media with different concentrations of D-glucal (0, 2.5, 5, 10, 20 or 40 mg/mL). (C) Growth curves of mycelia cultured in media with 40 mg/mL D-glucose, D-glucal, or D-galactal for 5 d. (D) Numbers of spores produced per mL culture with D-glucose, D-glucal, or D-galactal. Data are presented as means ± S.D. (n = 3).
