- Ethanol yields are expressed as % of theoretical and g ethanol produced per 100 g of dry straw. The maximum amount of ethanol that could be produced from 100 g dry straw is 18.5 g
-
aDuration of prehydrolysis + duration of SSF
-
b% of theoretical, based on the glucan content in the pretreated solids
-
cDue to mixing difficulties, the SSF at 20 % WIS was run for 192 h
