- What other characteristics should a plant species have to be a good candidate for use in making cellulosic biofuel?arrow_forwardSwitchgrass is used for ethanol production. The composition of the switchgrass is 37% cellulose, 24% xylan, 3% galactan, 4% arabinan, 20% lignin, 7% extractives, and 5% ash. A dilute acid pretreatment method is applied to the switchgrass before enzymatic hydrolysis and fermentation. The pretreatment hydrolyzes 10% hexosan and 90% pentosan into monomeric sugars. Approximately 30% of the hydrolyzed pentoses further react & are decomposed to furfural. Assume that there is no decomposition of the hydrolyzed hexoses. Further Assume that lignin, extractives, and ash do not change during the pretreatment. • How much of each lignocellulosic sugar (glucose, xylose, galactose, and arabinose) is produced when pretreating 1,000 kg (dry matter) switchgrass? How much furfural is formed? • Is water consumed or produced in these pretreatment hydrolysis and dehydration reactions? How much in each?arrow_forwardWhat is the key difference between reactions that result in the final product of fermentation to form lactic acid or alcohol?
