| 中文摘要 | A challenge for lignocellulosic pretreatment is how to retain hemicellulose as much as possible. To reduce the degradation of hemicellulose and increase the recovery of sugars, an effective pH pre-corrected liquid hot water pretreatment (LHWP) was developed by employing a small amount of NaOH (<= 5/100 g substrate) to accelerate the hemicellulose deacetylation and simultaneously pre-correct the acid hydrolyzate in situ. The results showed that the pH pre-correction can control the hydrolyzate pH. Under the pretreatment severity (PS) of 4.0, the pH pre-corrected LHWP reduced the hemicellulose degradation by 35.3-92.3%, decreased furfural formation by 90.5-99.8%. The highest hemicellulose recovery of 96.38% was obtained with pH pre-corrected by 2 g NaOH/100 g substrate. Enzymatic hydrolysis (EH) and simultaneous saccharification and fermentation (SSF) on the whole slurry from the pH pre-corrected LHWP showed that the hemicellulose retained in the solid residue did not bring significant resistance to cellulose EH (p = 0.837).
