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: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
