Switchgrass is used for ethanol production. The compositions of the switchgrass are 37% cellulose, 24% xylan, 3% galactan, 4% arabinan, 20% lignin, 7% extractives, and 5% ash. 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 are decomposed to furfural. Assume there is no decomposition of the hydrolyzed hexoses. How much sugars (glucose, xylose, galactose, and arabinose, respectively) are produced when pretreating 1,000 kg (dry matter) switchgrass?
