lignin degradation by white rot fungi on spruce Wood Shavings during short time solid state fermentations monitored by near infrared spectroscopy
Enzyme and Microbial Technology, 2006Co-Authors: Karin Fackler, Cornelia Gradinger, Barbara Hinterstoisser, Kurt Messner, Manfred SchwanningerAbstract:Due to their outstanding capability of degrading the recalcitrant biomacromolecule lignin, white rot fungi have been attracting interest for several technological applications in mechanical pulping and Wood surface modification. However, little is known about the time course of delignification in early stages of colonisation of Wood by these fungi. Using a Fourier transform near infrared (FT-NIR) spectroscopic technique, lignin loss of sterilised spruce Wood Shavings (0.4–2.0 mm particle size) that had been degraded by various species of white rot fungi could be monitored already during the first 2 weeks. The delignification kinetics of Dichomitus squalens, three Phlebia species (Phlebia brevispora, Phlebia radiata and Phlebia tremellosa), three strains of Ceriporiopsis subvermispora as well as the white rot ascomycete Hypoxylon fragiforme and the basidiomycete Oxyporus latemarginatus were determined. Each of the fungi tested was able to reduce the lignin content of spruce Wood significantly during the first week. The amount of delignification achieved by the selected white rot fungi after 2 weeks ranged from 7.2% for C. subvermispora (FPL 105.752) to 2.5% for P. radiata. Delignification was significant (P = 95%) already after 3 days treatment with C. subvermispora and P. tremellosa. Activities of extracellular ligninolytic enzymes (laccase, manganese peroxidase and/or lignin peroxidase), expressed by each of the tested fungi, were determined. Lignin was degraded when peroxidase activity was detected in the fungal cultures, but only a low level of correlation between enzyme activities and the extent of delignification was found.
