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...

Comparison of 1H qNMR and NIR spectroscopic methods to predict heartwood decay resistance in Dicorynia guianensis Amsh
2017 - IRG/WP 17-20601
Dicorynia guianensis is by far the most exploited wood in French Guiana, as it is an abundant tree species associated with good technological properties. However, the decay resistance of D. guianensis wood against lignivorous fungi pathogens is sometimes variable. Therefore, the development of tools to predict the decay resistance of D. guianensis heartwood is relevant in wood science and agrofore...

Evaluation of ecotoxicological effects of different coniferous wood treatments on two marine bioindicator species
2022 - IRG/WP 22-10999
Coniferous wood panels (Picea abies) were treated with two concentrations of copper-based impregnating agent to increase its durability in marine and brackish environment. In order to assess the environmental compatibility of the treatments a laboratory experiment was conducted with two marine invertebrate species: bivalve Mytilus galloprovincialis and a gastropod Steromphala albida. The bioindica...
