The influence of the buffer concentration on the acid production. pH (▽) and concentration of itaconate (■), malate (▲) and erythritol (◇) produced by A: U. maydis 2229 (solid lines) and B: U. cynodontis 2217 (dashed lines) after 120 h and C: U. maydis 2162 (dotted lines) after 72 h cultivation in screening medium containing different MES concentrations. The values are the arithmetic mean of two biological determinations. Error bars indicate deviation from the mean.
