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 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.

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 ...

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.

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 ...

12. Lignin Biosynthesis and Lignin Manipulation

2012
Many 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 ...

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 ...
