Microbial degradation of lignocellulose: the lignin component.

A new procedure was developed for the study of lignin biodegradation by pure or mixed cultures of microorganisms. Natural lignocelluloses were prepared containing C in primarily their lignin components by feeding plants l-[U-C]phenylalanine through their cut stems. Lignin degradation was observed in numerous soils by monitoring evolution of CO(2) from [C]lignin-labeled oak (Quercus albus), mapl...

Lignin degradation: A microbial approach

Enzymatic Degradation of Lignin in Soil: A Review

Lignin is a major component of soil organic matter and also a rich source of carbon dioxide in soils. However, because of its complex structure and recalcitrant nature, lignin degradation is a major challenge. Efforts have been made from time to time to understand the lignin polymeric structure better and develop simpler, economical, and bio-friendly methods of degradation. Certain enzymes from...

Biodegradation of lignocellulosics: microbial, chemical, and enzymatic aspects of the fungal attack of lignin.

Wood is the main renewable material on Earth and is largely used as building material and in paper-pulp manufacturing. This review describes the composition of lignocellulosic materials, the different processes by which fungi are able to alter wood, including decay patterns caused by white, brown, and soft-rot fungi, and fungal staining of wood. The chemical, enzymatic, and molecular aspects of...
