Lignin depolymerization through peroxide oxidation produces dicarboxylic acids (DCA), especially C4-DCA, like succinic acid. In this work, the effect of methoxy substituents on C4-DCA production using lignin model compounds (p-hydroxybenzoic acid, vanillic and syringic acid) hardwood softwood samples was studied. It concluded that increased reactivity toward oxidation. The acid yield higher for...

The most prominent aromatic feedstock on Earth is lignin, however, lignin valorization still an underrated subject. principal preparatory strategies for are fragmentation and depolymerization which help in the production of fuels chemicals. Owing to lignin’s structural heterogeneity, these result product generation requires tedious separation purification extract target products. bacterial genu...

This paper presents the results from an assessment of the application of a new molecular analytical procedure, CTMAH thermochemolysis, to study the chemical modi®cation of lignin by white-rot and brown-rot fungi. This technique di€ers from other molecular chemolysis procedures (e.g. TMAH thermochemolysis and CuO alkaline oxidation) as it enables one to determine the amount of hydroxylated aroma...

Ligninolytic extracellular enzymes, including lignin peroxidase, are topical owing to their high redox potential and prospective industrial applications. The prospective applications of lignin peroxidase span through sectors such as biorefinery, textile, energy, bioremediation, cosmetology, and dermatology industries. The litany of potentials attributed to lignin peroxidase is occasioned by its...

Background Lignin valorization has recently been considered to be an essential process for sustainable and cost-effective biorefineries. Lignin represents a potential new feedstock for value-added products. Oleaginous bacteria such as Rhodococcus opacus can produce intracellular lipids from biodegradation of aromatic substrates. These lipids can be used for biofuel production, which can potenti...

Wood is a highly intractable food source, yet many insects successfully colonize and thrive in this challenging niche. Overcoming the lignin barrier of wood is a key challenge in nutrient acquisition, but full depolymerization of intact lignin polymers has only been conclusively demonstrated in fungi and is not known to occur by enzymes produced by insects or bacteria. Previous research validat...
