Degradation of Lignin by Pyrolysis
2017Fast pyrolysis is an efficient technique for thermal degradation of lignin to bio-oils containing bio-phenols for the synthesis of adhesives, resins, and polymers. Lignin has a complex structure, and hence a large number of pyrolytic components are generated during the pyrolysis process.

Bacteria and lignin degradation
Frontiers of Biology in China, 2008Lignin is both the most abundant aromatic (phenolic) polymer and the second most abundant raw material. It is degraded and modified by bacteria in the natural world, and bacteria seem to play a leading role in decomposing lignin in aquatic ecosystems.

Radiation degradation of lignin
Chemistry of Natural Compounds, 1990An analysis is given of literature information on the radiation degradation of lignin. The following questions are discussed: 1) the formation of radicals in the radiolysis of lignin and compounds modeling it; 2) the chemical properties of irradiated lignin; 3) the low-molecular-mass products of the radiolysis of lignin; and 4) the radioprotector ...

Bacterial degradation of lignin
Enzyme and Microbial Technology, 1988Abstract During the year 1983, there was a breakthrough in the field of lignin biodegradation when fungal ligninases and their hydrogen peroxide requirement were described. A comparable progression has not yet occurred with ligninolytic bacteria, although it is expected to take place in the near future once depolymerizing enzymes are isolated ...

Biomimetic degradation of lignin
Journal of Biotechnology, 1993Abstract The ligninolytic cultures of Phenarochaete chrysosporium produce two major groups of lignin degrading enzymes, the lignin peroxidase (Tien and Kirk, 1983) and the manganese-dependent peroxidase (Kuwahara et al., 1984). Both enzymes are hemeproteins and catalyze the oxidation of lignin model compounds by one-electron oxidations.

Lignin is a complex high-molecular compound in which the phenylpropane units are linked to each other by a variety of carbon-to-carbon and ether linkages. Three cinnamyl alcohol precursors, p-coumaryl, coniferyl, and sinapyl alcohols are subjected to dehydrogenative polymerization to form lignin.

Lignin degradation by bacteria
2002Publisher Summary The complex aromatic polymer lignin comprises about 25% of the land based biomass on earth, and its recycling is a vital component of the earth's carbon cycle. Its breakdown involves multiple biochemical reactions. Though the role of fungal lignin peroxidases has been well established only in recent years, bacterial lignin ...

Abstract The substantial potential applications of lignin-degrading microbes and enzymes have spurred research on lignin biodegradation in recent years. As described here, that research has led to the discovery in the basidiomycete Phanerochaete chrysosporium of the first lignin-degrading enzymes and elucidation of their mode of ...
