Lignin Biosynthesis

Annual Review of Plant Biology, 2003
The lignin biosynthetic pathway has been studied for more than a century but has undergone major revisions over the past decade. Significant progress has been made in cloning new genes by genetic and combined bioinformatics and biochemistry approaches.

Lignin engineering

Current Opinion in Plant Biology, 2008
Lignins are aromatic polymers that are present mainly in secondarily thickened plant cell walls. Several decades of research have elucidated the main biosynthetic routes toward the monolignols and demonstrated that lignin amounts can be engineered and that plants can cope with large shifts in p-hydroxyphenyl/guaiacyl/syringyl (H/G/S) lignin ...

Lignin Valorization: Improving Lignin Processing in the Biorefinery

Science, 2014
Background Lignin, nature’s dominant aromatic polymer, is found in most terrestrial plants in the approximate range of 15 to 40% dry weight and provides structural integrity. Traditionally, most large-scale industrial processes that use plant polysaccharides have burned lignin to ...

Lignin and Lignin-Modifying Enzymes

2014
There is increasing worldwide interest in the use of ligninolytic fungi for bioremediation purposes and for biopulping applications. Three families of fungal enzymes, designated lignin-modifying enzymes (LMEs), consist of lignin peroxidases (LiPs), manganese peroxidases (MnPs), and laccases (LACs), and these play a key role in lignin biotransformation.

Enzymatic monitoring of lignin and lignin derivatives biooxidation

Journal of Microbiological Methods, 2016
Lignin 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.

A Biomimetic Approach to Lignin Degradation

2001
An 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 ...

Lignin hydrogenolysis: Tuning the reaction by lignin chemistry

International Journal of Biological Macromolecules
Replacing 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 ...

Lignin Recovery and Lignin-Based Products

2012
An 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.

Fucus ‘lignin’: A reassessment

Phytochemistry, 1984
A ‘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.
