Lignin degradation by biocatalysts is a key strategy to develop plant-based sustainable carbon economy and thus alleviate global climate change. This process involves synergy between ligninases auxiliary enzymes. However, enzymes within secretomes, which are composed of thousands enzymes, remain enigmatic, although several ligninolytic have been well characterized. Moreover, it challenge understand synergistic lignin via diverse array especially in bacterial systems. In this study, the coexpression network periplasmic proteome uncovers potential accessory for B-type dye-decolorizing peroxidases (DypBs) Pseudomonas putida A514. The catalytic DypBs-based multienzyme complex DypBs couple with quinone reductases nitroreductase participate redox cycling. They work superoxide dismutase induce Fenton reaction oxidation. A synthetic enzyme cocktail (SEC), recruiting 15 was consequently designed four functions. It overcomes limitation repolymerization, exhibiting capacity comparable that native secretome. Importantly, we reveal mechanism SEC-A514 cell system, incorporates advantages vitro catalysis vivo microbial catabolism. Chemical analysis shows system significantly reduces molecular weight lignin, substantially extends spectra functional groups, efficiently metabolizes derivatives. As result, 25% utilized, its average reduced 27%. Our study advances knowledge lignin-degrading multienzymes provides viable strategy.

Recent Advances in Depolymerization and High-Value Utilization of Lignin: A Review

Industrial & Engineering Chemistry Research, Год журнала: 2024, Номер 63(46), С. 19916 - 19935

Опубликована: Ноя. 7, 2024

Given the global greenhouse effect caused by excessive CO2 emissions and fossil energy exploitation, cleaner sources are crucial for modern developments. Lignin present in biomass is being considered to replace petroleum due its abundance reproducibility. Although depolymerization of lignin produce high-value chemicals has gained attention, it encounters significant challenges. possesses a high molecular weight, structural changes during separation often diminish potential producing value-added chemicals. This study reviews recent research on using three traditional methods, including hydrolysis, pyrolysis, hydrogenolysis. First, hydrolysis presented, where properties mechanisms under various conditions detailed. Subsequently, pyrolysis mechanism, products, methods (catalytic microwave molten salt pyrolysis) discussed detail. In addition, this provides comprehensive summary hydrogenolysis terms both solvent selection catalytic system. Finally, addresses challenges proposes solutions future research.
