Enzymatic monitoring of lignin and lignin derivatives biooxidation
Journal of Microbiological Methods, 2016Lignin oxidation was enzymatically monitored by measuring methanol released during the reaction. The methanol was oxidized to formaldehyde and hydrogen peroxide, and the latter used to oxidize ABTS to a product measured spectrophotometrically. The efficiency was comparable to the commonly used gas chromatography method.

Lignin hydrogenolysis: Tuning the reaction by lignin chemistry
International Journal of Biological MacromoleculesReplacing fossil resource with biomass is one of the promising approaches to reduce our carbon footprint. Lignin is one of the three major components of lignocellulosic biomass, accounting for 10-35 wt% of dried weight of the biomass. Hydrogenolytic depolymerization of lignin is attracting increasing attention because of its capacity of utilizing ...

A Biomimetic Approach to Lignin Degradation
2001An overview of the state of the art for the use of synthetic metalloporphyrins in the catalytic oxidation of lignin and lignin model compounds is presented. The biomimetic oxidation of 5-5â€2 condensed and diphenylmethane lignin model compounds with several water soluble anionic and cationic iron and manganese porphyrins in the presence of hydrogen ...

Fucus ‘lignin’: A reassessment
Phytochemistry, 1984A ‘lignin’ fraction isolated by the Bjarkman method from the marine brown alga Fucus uesiculosus has beenexamined by 13CNMR and degradative analysis, and shown to consist of polyphloroglucinols identical to thosecharacterized earlier from Fucus. No evidence for the presence of lignin in F. uesrculosus could be found.

12. Lignin Biosynthesis and Lignin Manipulation
2012Many research projects are currently exploring the options for manipulating lignin to allow more efficient biofuel production from plant biomass. The difficulties in degrading lignin arise from the polymer's complicated structure. Efforts to manipulate lignin must achieve the required improved properties for industrial processing without interfering ...

Lignin Recovery and Lignin-Based Products
2012An overview is given of the recovery and use of wood lignin. Most of the lignin produced today is lignosulfonate from sulfite pulping processes. Lignin from the more common kraft pulping process is also becoming available due to new technology. Another industrial source is as a byproduct from wood-based ethanol production.
