“…As mentioned above, the decrease in phenanthrene/chrysene ratio from OSS, CT to MP mousse could indicate some biodegradation (Pastor et al 2001, Zhou et al 2012. However, alkylated phenanthrenes in the oil mousse decreased at similar rates, suggesting that the weathering was not controlled by biodegradation, as the biodegradation rate decreases with the number of alkyl groups on the PAH nucleus (Prince 2002). Alternatively, alkylated phenanthrenes might be as labile as phenanthrene in the Gulf waters.…”

“…Biodegradation of cycloalkanes has been studied to a lesser extent than the biodegradation of n-alkanes and aromatic hydrocarbons (Prince, 2002;Van Hamme et al, 2003). Axenic bacterial strains hitherto reported to grow with cycloalkanes were aerobic.…”

Microbial nitrate-dependent cyclohexane degradation coupled with anaerobic ammonium oxidation

et al. 2010

An anaerobic nitrate-reducing enrichment culture was established with a cyclic saturated petroleum hydrocarbon, cyclohexane, the fate of which in anoxic environments has been scarcely investigated. GC-MS showed cyclohexylsuccinate as a metabolite, in accordance with an anaerobic enzymatic activation of cyclohexane by carbon-carbon addition to fumarate. Furthermore, long-chain cyclohexyl-substituted cell fatty acids apparently derived from cyclohexane were detected. Nitrate reduction was not only associated with cyclohexane utilization but also with striking depletion of added ammonium ions. Significantly more ammonium was consumed than could be accounted for by assimilation. This indicated the occurrence of anaerobic ammonium oxidation (anammox) with nitrite from cyclohexane-dependent nitrate reduction. Indeed, nitrite depletion was stimulated upon further addition of ammonium. Analysis of 16S rRNA genes and subsequent cell hybridization with specific probes showed that approximately 75% of the bacterial cells affiliated with the Geobacteraceae and approximately 18% with Candidatus 'Brocadia anammoxidans' (member of the Planctomycetales), an anaerobic ammonium oxidizer. These results and additional quantitative growth experiments indicated that the member of the Geobacteraceae reduced nitrate with cyclohexane to nitrite and some ammonium; the latter two and ammonium added to the medium were scavenged by anammox bacteria to yield dinitrogen. A model was established to quantify the partition of each microorganism in the overall process. Such hydrocarbon oxidation by an alleged 'denitrification' ('pseudo-denitrification'), which in reality is a dissimilatory loop through anammox, can in principle also occur in other microbial systems with nitrate-dependent hydrocarbon attenuation.

“…On rocky shores the usual response is to wash the oil back into the sea, and collect it with skimmers, as was done following the 1989 Exxon Valdez spill in Alaska [15]. Any residual oil will either leave the shoreline flocculated with small neutrally buoyant particles of silt [16], and be biodegraded [17], or eventually be biodegraded on the beach [3][4][5][6][7]. As we shall see below, the stimulation of this process by adding fertilizers has been shown to be safe and effective.…”

Bioremédiation des pollutions maritimes pétrolières -À long terme, la biodégradation constitue l'ultime étape du devenir du pétrole déversé en mer qui ne peut être ramassé ou brûlé. La stimulation de cette biodégradation est donc une option importante pour optimiser l'élimination du pétrole de l'environnement et minimiser l'impact environnemental d'un déversement. Pour le traitement de l'huile flottant à la surface de la mer, les produits dispersants sont intéressants car ils augmentent au maximum l'aire interfaciale disponible pour les attaques microbiennes et favorisent ainsi la biodégradation. Si le pétrole se répand sur les côtes, il est probable que la biodégradation soit limitée par des nutriments tels que l'azote et le phosphore, d'autre part, l'application raisonnée d'engrais stimule la biodégradation du pétrole résiduel en place. Ces approches constituent un parfait exemple de technologies environnementales modernes : fonctionner en s'appuyant sur les phénomènes naturels afin d'obtenir un nettoyage rapide tout en minimisant les effets indésirables sur l'environnement.Abstract -Bioremediation of Marine Oil Spills -In the long run, biodegradation is the eventual fate of oil spilled at sea that cannot be collected or burnt. Stimulating this biodegradation is thus an important option for maximizing the removal of oil from the environment, and minimizing the environmental impact of a spill. For handling oil while it is still floating on the sea surface, dispersants are advantageous because they maximize the surface area available for microbial attack, and stimulate biodegradation. If oil beaches on a shoreline, it is likely that biodegradation is limited by nutrients such as nitrogen and phosphorus, and the careful application of fertilizers stimulates the biodegradation of residual beached oil. These approaches epitomize modern environmental technologies; working with natural phenomena to achieve a more rapid clean-up while minimizing undesirable environmental impacts.
