Table 6 Ethanol yield per hectare from different varieties of sugarcane (55, 70, 74 and 120)

From: Impact of cultivar selection and process optimization on ethanol yield from different varieties of sugarcane

  55 70 74 120
Cane yields (wet ton/ha) 105.5a 108a 105.5a 65b
Sucrose content (kg/ton wet cane) 127.5 a 152 a 137 a 126b
Sugar juice content (kg/ton wet cane) 149a 163a 149a 140b
Bagasse content (kg/ton wet cane) 147a 127a 161a 133b
Ethanol yield (L/ha)     
1Juice ethanol 9 045 10 169 9 074 5 248
2Bagasse ethanol (glucose + xylose) 3 888 3 554 3 574 1 814
3Combined (juice + bagasse) 12 933 13 723 12 648 7 062
  1. 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).
  2. 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.
  3. 1Juice ethanol is the ethanol that can be produced by fermentation of juice sugars (sucrose, glucose and fructose).
  4. 2Bagasse ethanol is the ethanol that can be produced by fermentation of the xylose obtained after pretreatment and SSF of the pretreated bagasse.
  5. 3Combined ethanol yield is the realistic total ethanol that can be obtained from the sugar juice and bagasse.
