Summary: This study investigated the effects of using urea combined with steam explosion on the enzymatic hydrolysis and ethanol production of corn stover. The results showed that optimal conditions for ethanol production were 4.87% urea addition and 1.22 MPa steam pressure. The addition of urea and steam explosion significantly increased the reducing sugar yield and degradation rates of cellulose, hemicellulose, and lignin.

Summary: This study investigated the effect of the GVL/H2O pretreatment system on bamboo for enzymatic hydrolysis and ethanol fermentation. The results showed that the cellulose in bamboo could be effectively separated and converted into bioethanol through the GVL/H2O pretreatment system, with a high conversion yield. The recovered substrates could also be used for other high-valued utilization, and the fermentation inhibitors formed after pretreatment had weak inhibition to the subsequent reaction.

Summary: In this study, statistical design and mathematical modeling were used to investigate the fed-batch enzymatic hydrolysis process of steam-exploded sugarcane bagasse. A Box-Behnken experimental design was used to evaluate the effects of enzyme loading, stirring speed, and substrate total solids on glucose release after 48 hours of hydrolysis. A simplified kinetic model was used to fit the experimental data and predict the effects of substrate and enzyme intermittent feedings in fed-batch hydrolysis experiments. The proposed fed-batch procedure was found to significantly increase GlcEq productivity compared to batch experiments at 20 wt%.

Summary: This study introduces a novel combined pretreatment approach involving steam explosion and GVL/water delignification to improve the enzymatic saccharification efficiency of corn stalk. The method effectively removes lignin and enhances glucan content in the solid material, leading to significantly increased glucose concentration during high-solid loading enzymatic hydrolysis with relatively low cellulase addition. The combined pretreatment shows promise for green lignocellulosic biorefinery by fractionating corn stalk and producing a glucan-enriched solid with enhanced enzymatic digestibility.

Summary: This study fabricates nitrogen-doped porous carbon coembedded with lanthanum and cobalt (La-Co@NPC) as a dual-functional catalyst for sulfite oxidation and arsenic removal in the desulfurization process. The La-Co@NPC/S(IV) catalytic system generates strongly oxidizing free radicals for sulfite oxidation and oxidizes As(III) into As(V). The results show high efficiency in ammonium sulfite oxidation and arsenic removal, making it significant for the high-value recovery of sulfur resources in coal-fired desulfurization.

Summary: The research found that humic acids (HA) negatively affected enzymatic hydrolysis efficiency in lignocellulose pretreatment, but introducing metallic cations (Fe3+) to associate with HA can improve enzymatic hydrolysis efficiency. This strategy provides an economically viable means for future biorefinery developments to produce valuable biochemicals, biofuels, and biomaterials.

Summary: This study utilized enzymatic hydrolysis lignin (EHL) extracted from bio-ethanol production residue and purified it to remove cellulose and hemicellulose, obtaining purified lignin (EHL-P) through alkaline solution extraction. The thermal performance and pyrolytic product distribution of EHL-P-SE (obtained from EHL-P by steam explosion) were analyzed and compared with EHL-P. The results revealed differences in weight loss, char yields, and evolution of gaseous products between EHL-P and EHL-P-SE. The study also tracked the variations of phenols with increasing degradation temperature and found that demethoxylation was more likely to occur at higher temperatures.

Summary: This study investigated the pretreatment of reed using different alkali chemicals and found that ammonia and sodium sulfite had the best pretreatment effect. The pretreatment with 10 wt% of ammonia and 10% of sodium sulfite at 172 degrees C for 20 min resulted in the removal of 90.36% of lignin. The pretreated reed achieved 85.6% of enzymatic hydrolysis efficiency and 64.83% of total sugar yield.

Summary: This study investigated the potential of broom biomass to produce oligo- and monosaccharides through mild sulfite pretreatment and enzymatic hydrolysis. Response surface methodology was used to optimize the extraction of hemicellulose and achieve a 60% enzymatic yield. The mildest pretreatment conditions allowed for the separation of polysaccharides in oligomer form, while enzymatic hydrolysis successfully extracted sugars from the cellulose-rich residue.
