Additional file 4: Fig. S4. Malate and itatartarate production by various Ustilaginaceae and their mutants transformed with Umag_ria1, Uc_ria1, Pt_ria1, Si_ria1. Malate (gMal g GLC −1 , gITA g GLY −1 ) yield and itatartarate titer after 120 h or 384 h System Duetz® cultivations in screening medium containing glucose (GLC) and glycerol (GLY), respectively. A dash (–) indicates the negative control without an overexpression construct. Error bars indicate standard deviation from the mean (n = 3)
