Fig. 2From: Acetate as substrate for l-malic acid production with Aspergillus oryzae DSM 1863Comparison of malic acid production with initial acetic acid concentrations of 10–55 g/L. Cultures were incubated at 32 °C, 120 rpm in the presence of 90 g/L CaCO3. Acetate consumption and acid production was fitted using Eq. 1. Results are the mean of triplicate experiments and error bars indicate the standard deviation. HAc acetic acidBack to article page
