Fig. 4From: Acetate as substrate for l-malic acid production with Aspergillus oryzae DSM 1863Evaluation of malic acid production with different CaCO3 concentrations. Cultures were incubated at 32 °C, 120 rpm with 45 g/L acetic acid. Acetate consumption and acid production was fitted using Eq. 1. Results are the mean of triplicate experiments and error bars indicate the standard deviationBack to article page
