Comparison of different fermentation modes.

Mode	Ethanol concentration(%)	Ethanol yield(%)	Residual sugar (g/L)	Inulinase activity (U/mL)	COD of effluent (mg/L)	Remarks	Reference
SSF a	10.82 ± 0.37	40.2 ± 0.25	5.8 ± 0.11	20.18 ± 0.31	54612 ± 169	Different strains, same processb	11

^aSSF: Conventional simultaneous saccharification and fermentation; ASSF: Adsorptive simultaneous saccharification and fermentation.

^bDifferent strains, same process: Because the strains used in the reference could be not obtained in this study, we could only use the strains used in ASSF process, which was conducive to the comparison between different processes.
