Investigation on a Wood Decay Biomarker
2006 - IRG/WP 06-20336
HPLC evolution of beech wood extractives was investigated with or without exposure to Coriolus versicolor during one month. The nature and the quantity of extracts depends on the extraction conditions, but were also strongly influenced by the wood drying temperature and time leading to an important modification for higher drying temperature. After two weeks of exposure to Coriolus versicolor, resu...

Investigations on the durability of several Congo basin wood species
2015 - IRG/WP 15-10840
The sawdust of ten wood species was studied to assess their natural resistance to decay. The extractives and lignin contents were primarily determined (between 2.7-16.0% and 26.8-35.9% respectively) to give an overview of the chemical distribution. Then, a phytochemical screening (colorimetric methods) characterized the different chemical functional groups in all extracts studied. Antioxidant act...
