This study demonstrates sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL) for robust bioconversion of hardwoods. With only about 4% sodium bisulfite charge on aspen and 30‐min pretreatment at temperature 180°C, SPORL can achieve near‐complete cellulose conversion to glucose in a wide range of pretreatment liquor of pH 2.0–4.5 in only about 10 h enzymatic hydrolysis. The enzyme loading was about 20 FPU cellulase plus 30 CBU β‐glucosidase per gram of cellulose. The…

TLDR
For more accurate comparison of different pretreatment methods it is necessary to improve the assessment methods under real process conditions, as the various pret treatment methods give different types of materials.
Steam pretreatment of H(2)SO(4)-impregnated Salix for the production of bioethanol.
TLDR
Steam pretreatment of fast-growing Salix impregnated with sulfuric acid has been investigated, and high sugar recoveries were obtained and the highest yields of glucose and xylose after the subsequent enzymatic hydrolysis step were 92% and 86% of the theoretical, respectively, based on the glucan and xylan contents of the raw material.
Effect of Inhibitors Released during Steam‐Explosion Treatment of Poplar Wood on Subsequent Enzymatic Hydrolysis and SSF
TLDR
Steam‐exploded (SE) poplar wood biomass was hydrolyzed by means of a blend of Celluclast and Novozym cellulase complexes in the presence of the inhibiting compounds produced during the preceding steam‐explosion pretreatment process to show that untreated SE biomass during the enzymatic attack gives rise to a nonfermentable hydrolysate, which becomes fermentable when rinsed SE biomass is used.

TLDR
This paper reviews process parameters and their fundamental modes of action for promising pretreatment methods and concludes that pretreatment processing conditions must be tailored to the specific chemical and structural composition of the various, and variable, sources of lignocellulosic biomass.
