Lignin valorization through integrated biological funneling and chemical catalysis.
Lignin is an energy-dense, heterogeneous polymer comprised of phenylpropanoid monomers used by plants for structure, water transport, and defense, and it is the second most abundant biopolymer on Earth after cellulose. In production of fuels and chemicals from biomass, lignin is typically underused as a feedstock and burned for process heat because its inherent heterogeneity and recalcitrance m...
متن کاملLignin valorization: improving lignin processing in the biorefinery.
Research and development activities directed toward commercial production of cellulosic ethanol have created the opportunity to dramatically increase the transformation of lignin to value-added products. Here, we highlight recent advances in this lignin valorization effort. Discovery of genetic variants in native populations of bioenergy crops and direct manipulation of biosynthesis pathways ha...
متن کاملChemical Constituents from the Stem Barks of Plumeria rubra L.
Background and objectives: Plumeria rubra L. (Apocynaceae) is a deciduous shrub or small tree cultivated in subtropical and tropical countries. Its bark is prescribed to treat amoebic dysentery, dropsy, jaundice, scabies, gonorrhea, venereal affections and wounds. In the present research, we aimed to isolate and identify the chemical constituents of the bark of ...
متن کاملLignin valorization: lignin nanoparticles as high-value bio-additive for multifunctional nanocomposites
BACKGROUND Although conversion of low value but high-volume lignin by-product to its usable form is one of the determinant factors for building an economically feasible integrated lignocellulose biorefinery, it has been challenged by its structural complexity and inhomogeneity. We and others have shown that uniform lignin nanoparticles can be produced from a wide range of technical lignins, des...
متن کاملFrom gene to biorefinery: microbial β-etherases as promising biocatalysts for lignin valorization
The set-up of biorefineries for the valorization of lignocellulosic biomass will be core in the future to reach sustainability targets. In this area, biomass-degrading enzymes are attracting significant research interest for their potential in the production of chemicals and biofuels from renewable feedstock. Glutathione-dependent β-etherases are emerging enzymes for the biocatalytic depolymeri...
