Lignin-modifying enzymes of Flavodon flavus, a basidiomycete isolated from a coastal marine environment
Article Abstract:
The first report on the production of all three major classes of lignin-modifying enzymes (LMEs) by Flavodon flavus, which highlights the bioremediation potential of this organism in both terrestrial and marine environments, is presented. These three major classes of extracellular LMEs are manganese-dependent peroxidase (MNP), lignin peroxidase (LIP) and laccase. Low MNP and laccase activities were observed in high-nitrogen medium, but no LIP activity was detected. Meanwhile, relatively high MNP and moderate levels of laccases were seen in media containing lignocellulosic substrates, but LIP production was either absent or minimal.

Demonstration of laccase in the white rot basidiomycete Phanerochaete chrysosporium BKM-F1767
Article Abstract:
Laccase plate assays show that cultures of the Phanerochaete chrysosporium BKM-F1767 placed in a medium containing cellulose and ammonium tartrate produce extracellular laccase. Spectrophotometric assay and sodium dodecyl sulfate-polyacrylamide gel electrophoresis also show laccase activity in the concentrated extracellular culture medium. Induced laccase activity is observed in cultures containing cellulose but not in those containing glucose. Laccase is involved in lignin biodegradation.

Degradation of benzene, toluene, ethylbenzene, and xylenes (BTEX) by the lignin-degrading basidiomycete Phanerochaete chrysosporium
Article Abstract:
The simultaneous degradation of benzene, toluene, ethylbenzene and xylenes (BTEX) is discussed. Gas chromatography, high performance liquid chromatography and mineralization experiments were made on bacterial strains of the white rot fungus Phanerochaete chrysosporium to test its degradation of BTEX. The extentive degradation of BTEX was accomplished to include its toluates.
