An extracellular H2O2-requiring enzyme preparation involved in lignin biodegradation by the white rot basidiomycete Phanerochaete chrysosporium.
TLDR
An H2O2-requiring enzyme system was found in the extracellular medium of ligninolytic cultures of Phanerochaete chrysosporium and produced ethylene from 2-keto-4-thiomethyl butyric acid and partially degraded 14C-ring labeled lignin.About:

Lignin peroxidase of Phanerochaete chrysosporium
Ming Tien,T. Kent Kirk +1 more
TL;DR: The production of ligninase in shallow stationary cultures and in agitated cultures is described, which give somewhat more reliable and reproducible results than the agitated cultures.
Journal ArticleDOI
White-rot fungi and their enzymes for the treatment of industrial dye effluents.
TL;DR: The decolorization and detoxification potential of WRF can be harnessed thanks to emerging knowledge of the physiology of these organisms as well as of the biocatalysis and stability characteristics of their enzymes.
Journal ArticleDOI
Oxidation of persistent environmental pollutants by a white rot fungus.
TL;DR: Model studies suggest that the ability of Phanerochaete chrysosporium to metabolize these compounds is dependent on the extracellular lignin-degrading enzyme system of this fungus.
Journal ArticleDOI
Review: lignin conversion by manganese peroxidase (MnP)
TL;DR: The review summarizes and discusses different approaches to prove lignin decomposition in vitro and lists, in addition, other recalcitrant substances oxidizible by MnP.
Journal ArticleDOI
Separation and characterization of two extracelluar H2O2-dependent oxidases from ligninolytic cultures of Phanerochaete chrysosporium
TL;DR: Two H2O2‐dependent oxidases found in the extracellular medium of the white rot fungus Phanerochaete chrysosporium were separated by chromatography on blue agarose and an Mn2+‐dependent, lactate‐activated peroxidase was identified.

Ligninolytic enzyme system of Phanaerochaete chrysosporium: synthesized in the absence of lignin in response to nitrogen starvation.
P Keyser,T K Kirk,J G Zeikus +2 more
TL;DR: The results suggest that all or essential protein components of the ligninolytic enzyme system are synthesized as part of a series of physiological events that are initiated by nutrient nitrogen starvation.

Decomposition of lignin by white-rot fungi. II. Characterization of heavily degraded lignins from decayed spruce
T. Kent Kirk,Hou-min Chang +1 more
TL;DR: In this article, the authors compared three sound and three sound lignins from spruce on the basis of functional group analyses, spectroscopic characterizations and chemical degradation studies.
Journal ArticleDOI
The Involvement of Hydroxyl Radical Derived from Hydrogen Peroxide in Lignin Degradation by the White Rot Fungus Phanerochaete chrysosporium
TL;DR: The above results indicate that .OH derived from H2O2 is involved in lignin biodegradation by P. chrysosporium.

Effects of melecular oxygen on lignin degradation by Phanerochaete chrysosporium
S.S. Bar-Lev,T.K. Kirk +1 more
TL;DR: The study with Phanerochaete chrysosporium showed that immediately preceeding appearance of the lignin-degrading system the partial pressure of O2 determines the amount of ligninolytic activity that develops in cultures.
