The effect of selected imidazolium IL on the sugar consumption and lipid coefficient of G. fermentans. a Glucose consumption, b xylose consumption, and c lipid coefficient. Squares [Emim][DEP], circles [Emim]Cl, up triangles [Amim]Cl, down triangles [Bmim]Cl, left triangles [Emim][OAc], right triangles [Bmim][OAc], diamonds [Bzmim]Cl. 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 various concentration of IL; the C/N molar ratio was 163. The medium without IL was used as the control
