Purification and characterization of a putative virulence factor, serine protease, from Vibrio parahaemolyticus.

abstract：:The degradation of a series of nitroaromatic compounds by the lignin-degrading fungus Phanerochaete chrysosporium was examined. From 4-nitrotoluene (4-NT), several metabolic intermediates were identified. Initially, 4-NT was converted to 4-nitrobenzyl alcohol (4-NBA), followed by the oxidation reactions to form 4-nitr...
