Antinomic natural self-protection mechanism in long-lasting woods: a case study with three tropical species from French Guiana
2009 - IRG/WP 09-10696
We demonstrate in this work through 3 examples that Amazonian trees may specialize long-lasting woods by means of at least to different approaches. Wallaba impregnates its wood with large amounts of weakly antifungal compounds acting in synergy, while tatajuba and louro vermelho woods are naturally impregnated with antifungal agents. Comparison of biological activities in vitro and concentrations ...

Wood natural durability an asset to the circular economy of wood industry: valorization of waste from sawmills for the cosmetics sector through the ValorExtr@ct project
2019 - IRG/WP 19-10954
The French Guiana ‘s forest is characterized by its incredible biodiversity; more than 1200 wood species have been listed to date. Some argue that this diversity would be linked to the hot, humid climate with no seasonal variation, which would be ideal conditions for the installation of a constant "arms race" between predators and prey. Thus, to cope with biotic and abiotic attacks, wood species...
