Bio-productions of Hydrogen and Ethanol from Sugarcane

The technologies for hydrogen and ethanol productions from sugarcane juice were described based on information from laboratory-scale experiments. Bioconversions of sugarcane bagasse to hydrogen and ethanol were also discussed in terms of bagasse pretreatment and detoxification of the inhibitors in the hydrolysate. Two process configurations used in the ethanol fermentation process, i.e., separate hydrolysis/fermentation and simultaneous saccharification/fermentation, were also presented.
