Summary: In this study, a novel ternary deep eutectic solvent (DES) was developed to enhance component separation and enzymatic saccharification of wheat straw (WS), leading to the production of ethanol. The DES treatment effectively removed xylan and lignin from WS, resulting in high cellulose recovery and glucose yield. The maximum ethanol yield of the DES-treated WS was also improved.

Summary: The combination of waste distillery stillage and sugar-rich beet molasses for ethanol production showed promising results in increasing ethanol concentration and yield. However, attempts to use cellulases for hydrolysis to increase fermentable sugars were unsuccessful, leading to increased concentrations of ethyl acetate and other volatile by-products in the fermentation media. Further optimization of the cellulose enzymatic hydrolysis process is needed for efficient use of the raw material.

Summary: This study analyzed the biorefining process using deep eutectic solvent pretreatment, showing that acidic DES had better results in biomass refining. The choline chloride/lactic acid pretreatment process had higher bioethanol yield and lower MESP. Sensitivity analysis indicated that factors like cellulose conversion rate, acetone price, and lactic acid price significantly affected the MESP fluctuation.

Summary: This study focused on decomposing lignocellulosic biomass into monosaccharides using chemical and biological pretreatments, followed by long-term fermentation/co-fermentation for bioethanol production. Results showed high sugar utilization efficiency and bioethanol yield in the first cycle, but a decline in bioethanol production in subsequent cycles. The use of immobilized yeasts for co-fermentation was effective in improving bioethanol production from pretreated lignocellulosic biomass.

Summary: A combinatorial pretreatment process with liquid hot water (LHW) and sodium hydroxide was explored for ethanol production. The results showed that 200°C LHW combined with 1% NaOH achieved the highest ethanol yield of 50.90% and ethanol concentration of 22.71 g/L, which was attributed to the removal of hemicellulose and delignification. The study also analyzed the key factors related to biomass recalcitrance and found that an increased cellulose crystallinity index (CrI)/accessibility and decreased cellulose degree of polymerization (DP) improved fermentation yield.
