Biodegradation of Lignin by White Rot Fungi

Fungal Genetics and Biology, 1999
A review is presented related to the biochemistry of lignocellulose transformation. The biodegradation of wood constituents is currently understood as a multienzymatic process with the mediation of small molecules; therefore, this review will focus on the roles of these small molecular compounds and radicals working in concert with enzymes.

Vanillic acid metabolism by selected soft-rot, brown-rot, and white-rot fungi

Archives of Microbiology, 1982
Metabolism of vanillic acid, a product of lignin degradation, has been studied in selected representatives of soft-rot, brown-rot and white-rot fungi. All of the brown-and white-rot species examined decarboxylated vanillate to methoxyhydroquinone oxidatively.

Efficacy of Pinosylvins against White-Rot and Brown-Rot Fungi

Holzforschung, 1999
Summary Three stilbenes, pinosylvin (PS), pinosylvin monomethyl ether (PSM) and pinosylvin dimethyl ether (PSD), were extracted from white spruce (Picea glauca), jack pine (Pinus banksiana), and red pine (Pinus resinosa) pine cones, and their structures were confirmed by spectroscopic and chromatographic (HPLC, GC/MS, NMR and FTIR) analysis.

Biodegradation by White-Rot Fungi

2002
White-rot basidiomycete fungi selectively decay lignin in plant tissues. They are the only organisms known which are able to extensively mineralise lignin to carbon dioxide and water. This ability is unusual because lignin is a particularly complex aromatic macromolecule intrinsically resistant to enzymatic and hydrolytic attack.

Biological control of onion white rot

Soil Biology and Biochemistry, 1980
Abstract Six bacteria and one fungus isolated from sclerotia of Sclerotium cepivorum, the causal agent of white rot of onions, produced diffusible antibiotics antagonistic to growth of S. cepivorum on potato dextrose agar. Three of the bacterial isolates applied as seed treatments to onions grown in non-sterile muck soil in a controlled environment ...

Feasibility of bioremediation by white-rot fungi

Applied Microbiology and Biotechnology, 2001
The ligninolytic enzymes of white-rot fungi have a broad substrate specificity and have been implicated in the transformation and mineralization of organopollutants with structural similarities to lignin. This review presents evidence for the involvement of these enzymes in white-rot fungal degradation of munitions waste, pesticides, polychlorinated ...

Lignin degradeation by white rot fungi

Plant, Cell and Environment, 1987
Abstract. The wood‐degrading white‐rot fungus Phanerochaete chrysosporium, has been the subject of intensive research in recent years and, based upon isolation of the extracellular enzyme ligninase, major advances have now been made toward elucidating the mechanism by which this fungus degrades lignin.

Degradation of Xenobiotics by White Rot Fungi

1991
White rot fungi such as P. chrysosporium degrade the nonrepeating, nonstereoselective, insoluble polymer lignin under conditions of nutrient limitation. The attack on lignin principally involves extracellular peroxidases (ligninases) and hydrogen peroxide. Hydroxyl radicals may also make a significant contribution.

Allium white rot and its control

Soil Use and Management, 1990
Abstract. White rot ( Sclerotium cepivorum ) causes serious losses in Allium crops throughout the world. The pathogen produces sclerotia which survive for long periods and are the main source of inoculum.
