Summary: The aim of this study is to efficiently produce xylanase from agro-industrial waste. The culture conditions for three strains of Aspergillus fumigatus were optimized, and the most prolific strain produced the highest xylanase activity at pH 9.0 and 30°C using yeast extract as a nitrogen source. Wheat bran was found to be the most fermentable material, yielding 66.0 U/gds of xylanase. The synthesized xylanase displayed maximum activity at pH 6.0 and 45°C, with a strong affinity for birchwood xylan as opposed to other substrates.

Summary: The increasing population and industrialization have led to a higher demand for liquid fossil fuels, resulting in increased greenhouse gas emissions. Bioethanol, produced from lignocellulosic biomass through enzymes, is considered a potential alternative to fossil fuels. Cellulases have been identified as the limiting factor for bioethanol production, but advances in bioprocesses have significantly reduced their cost, making bioethanol production cost-effective.

Summary: The study investigated the biohydrogen and biomethane potential of palm oil mill effluent (POME) in a two-stage anaerobic digestion system under thermophilic and mesophilic conditions. The results showed that the best production potentials were obtained from POME with an initial 0.5 g-COD loading, and the energy yield achieved from two-stage AD was significantly higher than single-stage AD. Continuous production of hydrogen and methane revealed that the highest yields were generated at specific hydraulic retention times, with an overall COD removal of approximately 66.27%.

Summary: In this study, lignocellulolytic enzymes were efficiently produced from industrial crop wastes, specifically palm empty fruit bunches (EFB), using different fermentation modes and co-cultivation of filamentous fungi. Aspergillus tubingensis TSIP9 showed the highest cellulase and xylanase activities, while Trichoderma reesei QM9414 exhibited the highest beta-glucosidase activity. Co-cultivation significantly improved overall enzyme production, leading to enhanced activities of cellulase, xylanase, and beta-glucosidase after optimization and scaling up in a bioreactor with a helical impeller. These enzymes are highly active and stable under specific pH and temperature conditions, making them promising for low-cost production and biorefinery applications.

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.
