Transforming Lignin Biomass to Value: Interplay Between Ligninolytic Enzymes and Lignocellulose Depolymerization

Abstract Lignin is the main constituent of lignocellulosic biomasses, which have a significant untapped ability to replace ecologically unfavorable and non-renewable fossil fuels. The lignin broken down by ligninolytic bacteria, also use peripheral pathway transform heterogeneous derivatives into central intermediates like protocatechuate or catechol. By undergoing ring cleavage through -ketoadipate pathway, these become metabolites producing acetyl-CoA for internal product biosynthesis, including creation triacylglycerols polyhydroxyalkanoates. Expanding our understanding microbial communities, strains, enzymes bioprospecting can help us better understand metabolism aromatics. most viable idea sustainable development valorization biopolymers as well other high-value goods. This process now being used generate variety biopolymers, polyesters, epoxies, phenol resins, poly (lactic acids), hydroxyl alkanoates, polyurethanes. Furthermore, recalcitrance remained possible barrier efficient valorization, prompting several efforts design high-efficiency bioprocesses produce specific polymer types important bioproducts.
