Abstract: Our research aims at understanding the chemical resistance mechanisms of durable woods against fungi. Our ultimate goal is to isolate and identify antifungal compounds from these woods that could be used for the treatment of human fungal diseases. We therefore screened highly durable Amazonian wood selected from technical databases [1] and demonstrated that bioactive secondary metabolites responsible of the natural durability of the woods [2] can also be used to treat mycoses. This screening has given a very high ...

Chevalier, M., Roos, C., Tomi, F., Sutour, S., & Lebrini, M. (2015). Corrosion inhibition of C38 steel in 1M HCl media by alkaloidic extract from Xylopia frutescens amazonian tree. In ECS Transactions (Vol. 64, pp. 1–28).
Abstract: The use of Xylopia frutescens extract as a C38 steel corrosion inhibitor in 1 M HCl solution was investigated by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. Potentiodynamic polarization curves indicated that Xylopia frutescens extract behaves as mixed-type inhibitor. Graphical methods are illustrated by synthetic data to determine the parameter of CPE (α Q). The adsorption of the extract constituents was further discussed in view of angmuir adsorption isotherm. The effect of temperature on the inhibition efficiency was investigated using EIS and potentiodynamic polarization. SEM and EDX observations confirmed the existence of protective inhibitor film on metal surface. © The Electrochemical Society.

Gibernau, M. (2015). Pollination ecology of two Dieffenbachia in French Guiana. Aroideana, 38E(2), 38–66.
Abstract: The reproductive ecology of two species of Dieffenbachia (D. seguine [Jacq.] Schott and D. paludicola N.E. Br. ex Gleason) was studied at the Nouragues field station research in French Guiana. As in other known Dieffenbachia, the two studied species presented the classical cyclocephaline (dynastine scarab beetle) pollination system: Nocturnal anthesis with a strong odor, protogynous and short anthesis over 2 (3) days, female flowers being receptive on the first night and pollen being released on the second night. Inflorescences of D. seguine were visited by two species of scarab beetles (Cyclocephalini, Dynastinae): the dark brown Cyclocephala rustica and the black Erioscelis proba; while Inflorescences of D. paludicola were only visited by Erioscelis proba. Scarab beetles were efficient pollinators resulting in a high reproductive success even if some self-pollination can occur. Original data were gathered on flower and fruit predation leading to pollen and seed loss but their effect of the reproductive success still needs to be quantified.
