Enzyme hydrolysis improvement through the use of mechanical refining alone (7a) and refining + oxygen delignification (7b). Enzyme hydrolysis efficiency based on carbohydrate content in pretreated substrate (77%). From Koo[13]. GL = Green Liquor Pretreatment”. GL-4 = “Green Liquor Pretreatment with 4% Total Titratable Alkali”. GL-4-O = “Green Liquor Pretreatment with 4% Total Titratable Alkali + Oxygen Delignification”.
