Última Biodegradation du petrole en mer. Influence de l'apport d'azote et de phosphore sous forme minerale ArchiMer Lepetit, J; Guiot, J; Martin, Y; Tagger, S. To exploit the presence in the sea of microorganisms capable of degrading petroleum products a mineral fertilizer, containing immediatly assimilable nitrogen and phosphorus compounds, was used to increase the microbial population and therefore, the degradation potential of treated polluted waters. The fertilizer supply caused an increase in heterotrophic and hydrocarbon-splitting bacteria and an increase in the phytoplanktonic biomass. The latter is characterized by an increase in a few selected species; it constitutes an important supply of organic substances, and it is responsible for increasing the dissolved oxygen which is essential for petroleum oxidation. Supplying the fertilizer results in an increase in the treated water degradation potential and a...

Ano: 1984 URL: http://archimer.ifremer.fr/doc/1984/acte-1020.pdf Etude des liens trophiques au sein d'une communaute bacterienne selectionnee a partir d'un sediment marin sur le cyclohexene-4 dicarboximide-1,2 (THPI) ArchiMer Terrom, G; Gil, G; Lepetit, J. A bacterial community has been selected from a marine sediment on 4-cyclohexene-1,2 dicarboximide or THPI (fungicide). This community consists of nine strains. The "principal" strain, Photobacterium mandapamensis , degrades THPI by different metabolic pathways many of which require co-oxidative sequences. The other eight "auxiliary" strains occur at different states along the trophic chain formed by the "principal" strain, so increasing velocity and intensity of the THPI biodegradation.
