Photoelectrochemical degradation of lignin
Journal of Applied Electrochemistry, 2000We have evaluated the efficient of degradation of lignin by an photoelectrochemical process. Using a Ti/Ru0.1Sn0.6Ti0.3O2 electrode, a quartz reaction device and an artificial ultraviolet light, decoloration ratios higher than 70%, and reductions of 51% and 83% in TOC and total phenol products, respectively, were observed for a reaction time of 6 h ...

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.

Biotechnology of Lignin Degradation
1995Lignin is second only to cellulose in its abundance as a renewable carbon source. Because it serves to protect cellulose from most forms of microbial attack, its biodegradation also serves as the key to the utilization of cellulose. Lignin is a major waste product of the pulp and paper industry. Its utilization has long been envisioned and investigated.

Microbiological Degradation of Lignin
Russian Chemical Reviews, 1975The problems of the microbiological degradation of lignin, closely related to the solution of a number of important theoretical and practical problems, have been continually attracting attention in recent years. The most recent studies in this field are analysed in the present review.

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.

Lignin Degrading Fungal Enzymes
2016Lignin is a complex heterophenolic biopolymer present in plant cell walls. It supports plants growth by providing structural integrity, impermeability, protection against pathogenic infection and pest damage. Being the second most abundant polymer on the earth, it plays a major role in carbon recycling.

Lignin degradation by selected fungal species
Bioresource Technology, 2013As biological decomposition of plant biomass represents a popular alternative environmental-friendly and economically justified process, screening of ligninolytic enzyme systems of various fungal species is a topical study area. The goal of the study was to obtain clear insight into the dynamics of laccase, Mn-dependent peroxidase, and Mn-independent ...

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 ...

Enzymatic Degradation of Lignin
Agricultural and Biological Chemistry, 1962Oxidation of homogentisic acid and gentisic acid by the enzyme of Poria subacida and the effect of α,α′-dipyridyl on their oxidation were studied through oxygen uptake using Warburg apparatus. The oxidation products of these two acids were investigated by their ultraviolet absorption spectra and by paperchromatography.

Nylon biodegradation by lignin-degrading fungi
Applied and Environmental Microbiology, 1997The biodegradation of nylon by lignin-degrading fungi was investigated. The fungus IZU-154 significantly degraded nylon-66 membrane under ligninolytic conditions. Nuclear magnetic resonance analysis showed that four end groups, CHO, NHCHO, CH3, and CONH2, were formed in the biodegraded nylon-66 membranes, suggesting that nylon-66 was degraded ...
