Characterization of white zones produced on Pinus radiata wood chips by Ganoderma australe and Ceriporiopsis subvermispora

Abstract

White zones produced on biodegraded Pinus radiata wood chips were characterized by micro-localized-FTIR (Fourier Transformed Infra Red) spectroscopy and scanning electron microscopy. Both techniques permitted assignment of the white zones to a selective lignin removal process. Although both fungi studied have degraded lignin selectively in these restricted superficial areas, chemical analysis of the wood chips indicated that Ganoderma australe removed 16% of the initial amount of glucan at the 20% weight loss level. Ceriporiopsis subvermispora did not remove glucan at weight loss values below 17%. Prolonged biodegradation resulted in reduction of white zones by G. australe, and increased white zones from C. subvermispora decayed samples.
