A novel cost-effective technology to convert sucrose and homocelluloses in sweet sorghum stalks into ethanol

Table 1 Ethanol distillation of the fermented sweet sorghum bagasse

	Normal distillation		Distillation with 10% (w/w DM) NaOH
	Before	After	Before	After
Sample mass for distillation (g)	4000	4962	4076	4828
Ethanol content in the sample (g/100 g WM^a)	6.01	0.02	5.69	0.02
Ethanol in sample (g)	240.6	0.9	231.9	0.9
Recovered ethanol^b (g)		239.0		230.8
Ethanol recovery (%)		99.5		99.5

^aWM represents the wet mass of sweet sorghum bagasse; ^bThe mass of recovered ethanol is calculated by the concentration (g/mL) of the distillate multiplied by the volume (mL) of the distillate. DM, dry mass.
