Coula edulis baill an unknown wood species as an alternative to the main durable wood species used in Gabon
2019 - IRG/WP 19-10945
The Congo Basin hosts an exceptional biodiversity of trees, flora and fauna. However, the immense natural heritage of the forests in this area is increasingly threatened by many anthropogenic factors, due to selective exploitation of certain wood species. In Gabon, whose ecosystem is representative of this area, the forest represents nearly 80% of the national territory. Only a minority of wood sp...

Invasion and colonisation of bamboo culm material by stain and decay fungi
2002 - IRG/WP 02-10453
Two distinct stages of the fungal infection of bamboo culms can be identified: entry into the culm itself (invasion) and further colonisation by spread within the culm wall tissue. This laboratory study aimed to characterise different invasion strategies of a variety of fungi. Well-known isolates of white- (Coriolus versicolor, Schizophyllum commune), brown- (Coniophora puteana, Gloeophyllum tra...

Chemical composition, antitermite and antifungal activity of Dacryodes edulis oleoresin
2019 - IRG/WP 19-20653
Damages to wood structures and other cellulosic materials caused by wood destroying insects and fungi are estimated to several billions of dollars each year in the world. Among these, termites are considered as one of the most economically important pests for wooden structures. In the past, several wood protection chemicals like CCA, creosote, lindane or pentachlorophenol have been used. However, ...

Efficiency of three resin fractions from Aucoumea Klaineana Pierre, Canarium schweinfurthii Engl and Dacryodes edulis (G. Don) H. J. Lam from Gabon combined with Tebuconazole as wood preservatives
2022 - IRG/WP 22-10998
Pure resins from Aucoumea Klaineana, Canarium schweinfurthii and Dacryodes edulis were harvested and then hydro-distilled to obtain essential oils and purified resins fractions. Due to the potential leaching and volatility hazards of the compounds that constitute these fractions, resins and essential oils were combined with tebuconazole to produce both antifungal and anti-termite wood preservative...
