Phanerochaete flavido-alba ligninolytic activities and decolorization of partially bio-depurated paper mill wastes

Among 12 basidiomycetaceous fungal strains, Phanerochaete chrysosporium SC26 and K3 and Phanerochaete flavido-alba FPL 106507 were the most efficient in decolorizing paper mill wastes. Enzymatic activities attributable to both families of extracellular ligninases, lignin peroxidase (LiP) and manganese peroxidase (MnP), have been detected in P. flavido-alba FPL 106507. Both peroxidase activities seem to be implicated in the decolorization of partially bio-depurated paper mill waste waters, but LiP activity seems to play a more important role.
