“…The alkaline pretreatment with NaOH solution led to the highest glucose yield after enzymatic hydrolysis basis on per unit mass of dried raw material (0.245 g/g raw material). The ethanol yield of SSF on alkaline‐pretreated Napier grass obtained in this work (75.4%) was also higher than that from Napier grass pretreated by low‐moisture anhydrous ammonia (LMAA) and 1% NaOH . The dilute acid pretreatment yielded biomass that was relatively difficult to be hydrolyzed in the SSF process, in comparison with those treated by alkaline and two‐stage methods.…”

“…The ethanol yield of SSF on alkaline-pretreated Napier grass obtained in this work (75.4%) was also higher than that from Napier grass pretreated by low-moisture anhydrous ammonia (LMAA) 5 and 1% NaOH. 26 The dilute acid pretreatment yielded biomass that was relatively difficult to be hydrolyzed in the SSF process, in comparison with those treated by alkaline and two-stage methods. Results suggested that the removal of lignin from the lignocellulose feedstock favored the hydrolysis by cellulases and also the SSF process on the pretreated biomass.…”

“…However, it was found that the alkali-pretreatment was not a useful method for the biological process of napiergrass with its low lignin-content, because of the retardation of the fermentation rate by the inhibitory materials derived from the alkali-pretreatment and the loss of nutrients for the fermentation [19]. The LMAA-pretreatment did not take place in the retardation of fermentation, as shown in Figure 1 where the time profile of CO 2 evolution per 1 g of hollocellulose were compared among LMAA-pretreated, non-treated, and alkali-pretreated napiergrass.…”

“…However, the total ethanol yield was still low (44.2%). Moreover, usual alkali-pretreatment did not operate effectively to enhance the ethanol yield [19]. Therefore, we applied a LMAA pretreatment to enhance the ethanol yield from napiergrass.…”

“…EH and SSF are affected by chemical and physical properties of substrates including lignin, hemicelluloses and acetyl groups content, as well as cellulose crystallinity [2], polymerization degree, specific surface area [3,4], pore volume [5], particle size [6,7], among others. Several studies show that the lignin content negatively affects the enzymatic digestibility [4,[8][9][10][11][12], possibly acting as a physical barrier to restrict the access of cellulases to cellulose [5,10,13]. However, the way in which lignin protects the polysaccharides from enzymatic attack is not clear to date.…”
