Calcium lignosulfonate as a biopolymer component was incorporated into acrylonitrile butadiene rubber in the amount—50 phr. Four low-molecular organic molecules—1,4-butanediol, ethylene glycol, and two glycerols with different purity—were used plasticizers. They were applied compounds amount ranging from 5 to 30 The influence of plasticizers on curing process, cross-link density, morphology, physical–mechanical properties investigated. blooming also under observation. results revealed that application resulted deceleration kinetics reduction torque increments, pointing decrease compounds’ viscosity. This subsequently confirmed by rheological measurements. softened matrix well filler. higher polarity plasticizer, plasticizing effect lignosulfonate. increased following order: 1,4-butanediol < glycol glycerols. Softened formed small, soft filler-like domains distributed within matrix. Good compatibility adhesion between their interface observed, leading enhancement tensile characteristics vulcanizates plasticized

Recent Advances in Characterization and Valorization of Lignin and Its Value-Added Products: Challenges and Future Perspectives

Biomass, Год журнала: 2024, Номер 4(3), С. 947 - 977

Опубликована: Сен. 2, 2024

Lignin, the earth’s second-most abundant biopolymer after cellulose, has long been relegated to low-value byproducts in pulp and paper industry. However, recent advancements valorization are transforming lignin into a sustainable versatile feedstock for producing high-value biofuels, bioplastics, specialty chemicals. This review explores conversion of lignin’s complex structure, composed syringyl (S), guaiacyl (G), p-hydroxyphenyl (H) units, value-added products. We critically assess various biochemical analytical techniques employed comprehensive characterization. Additionally, we explore strategies upgrading functionalization enhance its suitability advanced biomaterials. The emphasizes key areas valorization, including catalytic depolymerization methods, along with associated challenges advancements. discuss potential as diverse products such carbon fibers, adhesives, phenolic compounds. Furthermore, briefly inherent properties UV protectant antioxidant, alongside incorporation polymer blends composites. By presenting case studies from literature, this highlights significant economic environmental benefits waste reduction, lower greenhouse gas emissions, decreased reliance on non-renewable resources. Finally, address future perspectives achieving large-scale, techno-economically feasible, environmentally valorization.

Manganese Peroxidase Participates in the Liquid–Solid–Gas Triphase Regulation on Microbial Degradation of Lignocellulose in Solid‐State Fermentation

Biotechnology and Bioengineering, Год журнала: 2025, Номер unknown

Опубликована: Янв. 14, 2025

The three-phase structure of solid-state fermentation (SSF) directly affects substrate degradation and efficiency. However, the mechanism regulation on lignocellulose utilization microbial metabolism is still unclear. Based comparative transcriptome analysis, a degrading enzyme, manganese peroxidase (GlMnP), which was significantly affected by water stress meanwhile related to triphase utilization, screened reveal using Ganoderma lucidum as reference strain. results showed that GlMnP participates in positively regulating activity carboxymethylcellulase (CMCase), filter paper (FPAse), laccase (LACase) enzymes, indirectly negatively redox levels microorganisms. In addition, can also control glycolysis rate enhance utilization. indicated liquid-solid-gas G. SSF.
