Ethanol production performance of S. stipitis NRRL Y-7124 using three different fermentation medium

Fermentation medium	Ethanol (g/l)	YX/S	YP/S	Qp	Qx	Qs
1	8.6 ± 0.1	0.26	0.22	0.12	0.14	0.55
2	8.1 ± 0.1	0.33	0.19	0.11	0.19	0.58
3	7.4 ± 0.2	0.34	0.18	0.10	0.20	0.58

Fermentation medium #1 (detoxified sugarcane bagasse acid hydrolysate + RBE + ammonium sulfate + calcium chloride), fermentation medium #2 (detoxified sugarcane bagasse acid hydrolysate + yeast extract + peptone) and fermentation medium #3 (detoxified sugarcane bagasse acid hydrolysate + yeast extract + peptone + malt extract) after 72 h of incubation

Y_x/s biomass yield and Y_P/S ethanol yield are in g/g and Q_x biomass productivity, Q_p ethanol productivity and Q_s sugar consumption rate in g/l h
