Summary: Supplementing commercial xylanase and cellulase with selected debranching enzymes only resulted in slight enhancement of enzymatic hydrolysis of wheat bran autohydrolysis residues, while a blend of enzymes from Aspergillus niger and Eupenicillium parvum achieved synergistic efficacy in this context. Using an equal mixture blend of these enzymes with the addition of ferulic acid esterase and further separation using an HP-20 resin, efficient wheat bran enzymatic saccharification and associated ferulic acid release can be achieved.

Summary: This study aims to recover ferulic acid from corn fibre through hydrothermal pretreatment and enzymatic hydrolysis, in order to produce natural extracts with high ferulic acid recovery yield and assess their antioxidant and antiproliferative properties, as well as cytotoxicity. Different enzyme preparations were tested for releasing ferulic acid from corn fibre, with Ultraflo (R) XL showing the best results. The use of hydrothermal pretreatment prior to enzymatic hydrolysis significantly increased the recovery yield of ferulic acid, while improving the quality of the extract in terms of bioactivity.

Summary: A gene encoding cold-adapted carboxylesterase in Arthrobacter soli Em07 was cloned and expressed in Escherichia coli, resulting in a carboxylesterase enzyme with a molecular weight of 37.2 KDa. The enzyme exhibited optimum activity at 10 degrees C and pH 7.0. Under the same conditions, the enzyme could degrade 20 mg of enzymatic pretreated de-starched wheat bran (DSWB) to produce 235.8 µg of ferulic acid, which was 5.6 times more than the control. Compared to chemical strategies, enzymatic pretreatment is environmentally friendly and the by-products are easily treated, providing an effective method for high-value utilization of biomass waste in agriculture and industry.

Summary: Historically, wheat and rye bran have been widely used in bakery production, with the majority of grain cultivated for flour manufacturing. However, the limited value of bran in food production is due to its structural complexity. By utilizing a biorefining process with multi-enzyme complexes, ferulic acid production from bran can be significantly increased.

Summary: Biocatalytical upgrading of side streams from agricultural biomass into multifunctional materials can increase the circularity of food and material systems. In this study, we designed radical scavenging hydrogels with mechanical integrity and protective effects against reactive oxygen species using enzymatic crosslinking of arabinoxylans (AX) extracted from corn fibre. The influence of two enzymatic systems, laccase/O-2 and peroxidase/H2O2, on the biochemical structure, assembly, properties, and radical scavenging activity of the hydrogels was compared. The results showed that the enzymatic system used for crosslinking affected the network organization and properties of the hydrogels.

Summary: The study focuses on the influence of surface chemical composition of lignocellulosic fibres on the products formed during reactions, utilizing a data-mining approach to analyze the relationship between different parameters. Crystalline and amorphous cellulose, xylans, mannans, and lignins were found to be correlated with specific reaction products at 25 degrees C, while only lignins and xylan were correlated at 60 degrees C. The study reveals the importance of fibres' surface composition in determining the extractive profiles and overall reaction outcomes.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
