Aniba rosaeodora – antitermitic – european standard – screening test. |
| Abstract |
Aniba rosaeodora, is a slow growing evergreens of the Lauraceae family which are
indigenous over a wide range of the Greater Amazon Region (the Guianas and Venezuela, Brazilian Amazon…). The essential oil obtained from the wood has a characteristic aroma and is a long-established ingredient in the more expensive perfumes. The wood is also composed with alkaloid compounds like anibin. These compounds contribute to the protection of the wood against insects and fungi. This work is focused on the valorization of steam distillated sawdust; the sawdust was extracted with methanol in order to study the antitermitic activity of the extract. The methanolic extract shows an efficacy against termites at low concentrations according to the EN 117 standard. |

| Abstract |
Aniba rosaeodora, is a slow growing evergreens of the Lauraceae family which are indigenous over a wide range of the Greater Amazon Region (the Guianas and Venezuela, Brazilian Amazon…). The essential oil obtained from the wood has a characteristic aroma and is a long-established ingredient in the more expensive perfumes. Around the olfactive characteristic of the essential oil is due to the presence of levogyre linalol. The steam distilled wood oil is obtained in a yield ranging around 1% and up to 90% of the oil consists of optically active linalol. This work is focused on the valorization of steam distillated sawdust, waste obtained from extraction of essential oil. After steam distillation, the sawdust was extracted by ethyl acetate and methanolic solvents and the antifungal activity was evaluated against basidomycetes fungi. The both extracts were active in vitro against white and brown rot fungi and allowed to propose these extractives as wood preservative agent. |

| Abstract |
L’UMR Ecofog étudie les forêts tropicales guyanaises, leur diversité et leur fonctionnement L’équipe « Ecologie des Communautés et des Ecosystèmes » comprenant le laboratoire de microbiologie des sols a pour mission d’étudier certains organismes pour mieux les comprendre. Dans les sols guyanais d’une part des bactéries sont capables de nitrifier et de dénitrifier en anaérobiose mais leur identification n’est pas encore faite, d’autre part il existe un panel de champignons qui ne sont pas répertoriés. Par conséquent il faut identifier les bactéries capables de nitrifier et dénitrifier en anaérobiose mais aussi lister les champignons récoltés sur divers sites. Cette identification se fait à l’aide des outils de biologie moléculaire qui permettent d’obtenir des séquences à partir de l’ADN extrait des souches bactériennes isolées en culture ou de fragments de champignons récoltés. Les séquences obtenues sont confrontées aux bases de données de référence ce qui permet d’identifier les espèces en présence. Ce stage de six semaines a mis en évidence 7 souches bactériennes anaérobies isolées des sols et devrais permettre de cataloguer des champignons. |
