Mode of coniferous wood decay by the white rot fungus Phanerochaete carnosa as elucidated by FTIR and ToF-SIMS

The softwood degrading white-rot fungus, , was investigated for its ability to degrade two coniferous woods: balsam fir and lodgepole pine. grew similarly on these wood species, and like the hardwood-degrading white-rot fungus , demonstrated selective degradation of lignin, as observed by Fourier transform infrared spectroscopy and time-of-flight secondary ion mass spectrometry (ToF-SIMS). Lignin degradation across cell walls of decayed pine samples was also evaluated by ToF-SIMS and was shown to be uniform. This study illustrates softwood lignin utilization by a white-rot fungus and reveals the industrial potential of the lignocellulolytic activity elicited by this fungus.
