aThe cane yield, sugar juice, sucrose and bagasse content for varieties 55, 70 and 74 were provided by SASRI, and they represent the average of two harvests (2009 and 2011).
bThe cane yield, sugar juice and bagasse content for sample 120 were obtained from the literature according to the average values of the industrial sugarcane.
1Juice ethanol is the ethanol that can be produced by fermentation of juice sugars (sucrose, glucose and fructose).
2Bagasse ethanol is the ethanol that can be produced by fermentation of the xylose obtained after pretreatment and SSF of the pretreated bagasse.
3Combined ethanol yield is the realistic total ethanol that can be obtained from the sugar juice and bagasse.
