“…g -1 DW at SF of 3.94 for SPS. For both presoaking conditions (SPS and WPS, Fig.1), the extraction 10 yields increased with the increase of SF until a SF of 3.94 which is in line with yields obtained after treatment of wood chips of Norway spruce (17, 19 and 43 mg. g -1 at SF of 2.7, 3 and 3.4 respectively) (Wojtasz-Mucha et al, 2017). A further increase of the SF of treatment led to a strong decrease in the hemicellulose's recovery.…”

“…Several publications described the extraction of hemicelluloses in oligomeric and/or polymeric forms from agricultural residues (Krawczyk et al, 2008;Schultz et al, 1984;Sun et al, 2014) or wood (Palm and Zacchi, 2003;Simangunsong et al, 2018;Wojtasz-Mucha et al, 2017) in the liquid effluents of a steam explosion pretreatment. In fact, this process has been shown to be effective in opening up the lignocellulose structure, increasing the accessibility of polysacharides to hydrolysis.…”

“…Hot water pretreatment is a typical biomass pretreatment technology which is conducted on biomass at high temperature (≥160 °C) in a sealed vessel with liquid water . Under such conditions, the cleavage of acetyl groups first occurs on acetylated hemicelluloses such as glucomannan, glucuronoxylan and arabinoxylan . The deacetylation process results in free acetyl groups, which increases the acidity of the environment.…”

“…[22][23][24][25][26] Under such conditions, the cleavage of acetyl groups first occurs on acetylated hemicelluloses such as glucomannan, glucuronoxylan and arabinoxylan. 27 The deacetylation process results in free acetyl groups, which increases the acidity of the environment. The pH of the process ranges from 2-4 depending on the type of biomass as well as the pretreatment temperature.…”
