The Deepwater Horizon oil spill is unparalleled among environmental hydrocarbon releases, because of the tremendous volume of oil, the additional contamination by dispersant, and the oceanic depth at which this release occurred. Here, we present data on general toxicity and mutagenicity of upper water column waters and, to a lesser degree, sediment porewater of the Northeastern Gulf of Mexico (NEGOM) and west Florida shelf (WFS) at the time of the Deepwater Horizon oil spill in 2010 and…

Paul et al. imply that the spill has a major lingering acute toxicity, but they neglect the following: the magnitudes of field responses under documented field exposures are inconsistent with the much higher exposures required to demonstrate such responses; field samples exhibited stimulatory effects of the same magnitude as samples judged to be toxic, seriously questioning the precision and accuracy of the tests for delineating toxicity gradients.

Results have shown an unexpectedly rapid response of deep-sea Gammaproteobacteria to oil and gas and documented a distinct succession correlated with the control of the oil flow and well shut-in.

The data suggest that hydro - carbon-degrading bacteria are inhibited by chemical dispersants, and that the use of dispersants has the potential to diminish the capacity of the environment to bioremediate spills.

Hydrocarbon-Degrading Bacteria and the Bacterial Community Response in Gulf of Mexico Beach Sands Impacted by the Deepwater Horizon Oil Spill

It is concluded that oil contamination from the DH spill had a profound impact on the abundance and community composition of indigenous bacteria in Gulf beach sands, and evidence points to members of the Gammaproteobacteria (Alcanivorax, Marinobacter) and AlphaproteOBacteria (Rhodobacteraceae) as key players in oil degradation there.
Deep-Sea Oil Plume Enriches Indigenous Oil-Degrading Bacteria

It is reported that the dispersed hydrocarbon plume stimulated deep-sea indigenous γ-Proteobacteria that are closely related to known petroleum degraders, and the potential exists for intrinsic bioremediation of the oil plume in the deep-water column without substantial oxygen drawdown.
Propane Respiration Jump-Starts Microbial Response to a Deep Oil Spill

Investigation of deep underwater hydrocarbon plumes in the Gulf of Mexico found propane and ethane trapped in the deep water may promote rapid hydrocarbon respiration by low-diversity bacterial blooms, priming bacterial populations for degradation of other hydrocarbons in the aging plume.
