The cell morphology of G. fermentans after 4 days of fermentation in the presence of selected imidazolium IL. a Control, b [Emim][DEP], c [Emim]Cl, d [Amim]Cl, e [Bmim]Cl, f [Bzmim]Cl, g [Emim][OAc], and h [Bmim][OAc]. The fermentation medium contained (g/L): glucose 40, xylose 20, peptone 1.05, yeast extract 0.375, MgSO4 0.4, NaH2PO4 2.0, MnSO4·7H2O 0.003, CuSO4·5H2O 0.0001, and 30 mM IL. The C/N molar ratio was 163. The medium without IL was used as the control
