Summary: This study reports the role of high moisture pelleting in improving the enzymatic digestibility of corn stover for ethanol production. Pelleting increases the glucan conversion from 8.2% to 15.5% at 5% solid loading. The composition analysis shows that loose and pelleted corn stover have similar nondissolvable compositions, but their extractives are different. The improved digestibility may be attributed to decreased particle size, improved substrate accessibility, and hydrolysis of cross-linking structures induced by pelleting.

Summary: Based on alkaline H2O2 pretreatment, the effects of reaction time, alkali concentration, and H2O2 concentration on the enzymatic digestion of corn stover were examined using photocatalytic alkaline H2O2 pretreatment (U-AHP). The optimum process conditions were found to be 1% NaOH, 2% H2O2, and a reaction time of 8 h, resulting in a lignin removal efficiency of 90.2% and a saccharification yield of 94.7%. Furthermore, U-AHP pretreatment caused structural damage to the maize straw and increased the crystallinity of the cellulose, suggesting a complex and multiple synergistic reaction mechanism.

Summary: This study investigated the feasibility of using corn stover hydrolysate (CSH) as a carbon source for the production of palmitoleic acid (POA) by engineered S. cerevisiae. Although the growth of yeast was inhibited by CSH to some extent, the POA production with CSH was slightly higher than that with pure glucose. The C/N ratio of 120 and the addition of 1 g/L lysine increased the POA titer. Under optimized conditions, a high POA content of 57.5% (v/v) and a highest POA titer of 6.56 g/L were achieved.

Summary: High-density culture is crucial for commercial-scale biodiesel production from low-cost lignocellulosic feedstocks. This study achieved high solids content saccharification of corn stover and obtained liquid hydrolysates for seed culture, fermentation, and feeding during fed-batch culture. Cutaneotrichosporon oleaginosum showed excellent capacity for lipid production using the fed-batch culture mode. Overall, the use of fed-batch mode resulted in higher hydrolysis yield and lipid yield, making it suitable for high-quality biodiesel production.

Summary: This research demonstrates that thioglycolic acid (TA) significantly accelerates Fenton pretreatment (FP) of corn stover (CS) and improves enzymatic hydrolysis of cellulose and xylan. TA-assisted FP greatly improves the removal of hemicellulose and lignin, resulting in an increase in pore volume, pore size, and cellulose exposure, thus promoting the enzymatic saccharification of CS.

Summary: The study demonstrates that pretreatment using ethylene glycol and dilute sulfuric acid for lignocellulose fractionation is a simple, efficient, and promising process for corn stover biorefinery. Delignification and cellulose retention rates are high, leading to a significant increase in enzymatic hydrolysis sugar yield compared to untreated corn stover. The regenerated lignin can also be utilized to produce renewable aromatic chemicals and alkane fuels.

Summary: This study investigated the depolymerization products, biomethane production, and microbial community of corn stover depolymerized with urea using a hydrothermal approach. The addition of urea facilitated the breakage of the ester bonds in lignocellulose structure, increasing the levels of volatile fatty acids and phenol. Depolymerization with 2% urea and 10 min of hydrothermal time produced higher cumulative biomethane yield. The combined depolymerization enhanced the acetate-methane pathway by promoting the growth of specific microbial species, resulting in increased biomethane production.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
