Summary: Syringic acid pretreatment was found to coproduce xylooligosaccharides, glucose, and less-condensed lignin from sugarcane bagasse. Syringic acid acted as a catalyst and lignin condensation inhibitor during the pretreatment. The addition of syringic acid increased the glucose yield and decreased the degree of lignin condensation.

Summary: Recently, mild acid hydrolysis has been proposed as a novel method to transform biomass into bioplastics. However, the alkaline hydrolysis of plant residues has not been studied for this purpose. In this study, a comprehensive comparative analysis was conducted on the physicochemical, thermal, mechanical, and morphological properties of bioplastics produced by acid and alkaline hydrolysis from two different plant residues. The results showed that the alkaline hydrolysis produced bioplastics with superior mechanical and barrier properties compared to the acid hydrolyzed biomass.

Summary: This study investigated the effect of sulfuric acid-based phenoxyethanol pretreatment on the enzymatic digestibility of bamboo by examining the changes in lignin/xylan content and intercellular structures. The highest removal of lignin and xylan, achieved by pretreatment with a phenoxyethanol-acid ratio of 4:1 at 120 degrees C, resulted in pretreated bamboo with an enzymatic digestibility of 79.25%. Micro-computed tomography revealed that the macrostructure of bamboo cell wall was destroyed, exposing the macrofibers. Fluorescence microscopy showed the removal of lignin from the intercellular complex layer and a more severe destruction of the hemicellulose main chain during pretreatment. The structures of dissolved lignin in the pretreatment hydrolysate varied with the phenoxyethanol-acid ratio used.

Summary: In this study, molded fiber products (MFPs) were prepared using enzymatic hydrolysis lignin (EHL) as a bio-phenol, compounded with Lewis acid-modified fibers. The reactivity of enzymatic lignin was improved by hydroxylation modification, resulting in enhanced mechanical properties of the MFPs through the generation of a resin structure. The application of high lignin content fibers in molded fibers is expected to be promoted by the results of this study.

Summary: This study reported cubosomes stabilized by two types of softwood hemicelluloses for the first time, showing that SSL-extracted hemicellulose yields the most stable cubosomes based on monoolein (GMO) without significantly affecting their size, morphology, and inner structure. The stability of these particles was also tested under physiological conditions relevant to possible application as drug carriers, indicating their potential in nanomedicine platforms.

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.

Summary: This study investigated the impact of magnetite on the nitrogen cycle of pig manure biostabilisation. The addition of magnetite increased N2O emissions and decreased NH3 emissions during composting. It also increased the total nitrogen content but should be considered for its significant increase in N2O emissions in engineering practice.
