The Deepwater Horizon oil spill was one of the largest oil spills in history, and the fate of this oil within the Gulf of Mexico ecosystem remains to be fully understood. The goal of this study—conducted in mid-June of 2010, approximately two months after the oil spill began—was to understand the key role that microbes would play in the degradation of the oil in the offshore oligotrophic surface waters near the Deepwater Horizon site. As the utilization of organic carbon by bacteria in the… 
Microbial responses to the Deepwater Horizon oil spill: from coastal wetlands to the deep sea.
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.
Rapid degradation of Deepwater Horizon spilled oil by indigenous microbial communities in Louisiana saltmarsh sediments.
It is suggested that Gulf of Mexico marsh sediments have considerable biodegradation potential and that natural attenuation is playing a role in impacted sites.
Microbial degradation of hydrocarbons in the marine environment, with a focus on the microbial response to the Deepwater Horizon oil spill
The release of petroleum hydrocarbons into marine environments can occur naturally as well as through anthropogenic activities. The entry of hydrocarbons in the environment can lead to changes in
Nutrient depletion as a proxy for microbial growth in Deepwater Horizon subsurface oil/gas plumes
The Deepwater Horizon accident resulted in a substantial uncontrolled hydrocarbon release to the northern Gulf of Mexico, much of which was entrained in deep submerged plumes. While bio-degradation
Response of microbial communities to oil spill in the Gulf of Mexico: A review
The response mechanism of microorganisms and how they help in hydrocarbon degradation are outlined and factors such as nutrient limitation, hydrocarbon availability, ocean mixing and circulation among others limit the rate at which microbial communities degrade hydrocarbons.
Microbial Dynamics Following the Macondo Oil Well Blowout across Gulf of Mexico Environments
The Macondo blowout released roughly 5 million barrels of oil and up to 500,000 tons of natural gas into Gulf of Mexico at a depth of 1500 meters. Inarguably, the gas released from the Macondo
Marine Oil Biodegradation.
Data that encompass everything from the ecosystem to the molecular level are needed for understanding the complicated process of petroleum biodegradation in marine environments.


A Persistent Oxygen Anomaly Reveals the Fate of Spilled Methane in the Deep Gulf of Mexico
This methane release simulates a rapid and relatively short-term natural release from hydrates into deep water and suggests that a vigorous deepwater bacterial bloom respired nearly all the released methane within this time, and that by analogy, large-scale releases of methane from hydrate in the deep ocean are likely to be met by a similarly rapid methanotrophic response.
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.
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.
Oil carbon entered the coastal planktonic food web during the Deepwater Horizon oil spill
The Deepwater Horizon oil spill was unprecedented in total loading of petroleum hydrocarbons accidentally released to a marine ecosystem. Controversial application of chemical dispersants presumably
Tracking Hydrocarbon Plume Transport and Biodegradation at Deepwater Horizon
The Deepwater Horizon blowout is the largest offshore oil spill in history. We present results from a subsurface hydrocarbon survey using an autonomous underwater vehicle and a ship-cabled sampler.
Fate of dispersants associated with the deepwater horizon oil spill.
It is shown that DOSS was sequestered in deepwater hydrocarbon plumes at 1000-1200 m water depth and did not intermingle with surface dispersant applications, and underwent negligible, or slow, rates of biodegradation in the affected waters.
Enhanced bacterioplankton activity after the Prestige oil spill off Galicia, NW Spain
Investigation of the response of coastal bacterioplankton communities to the 'Prestige' oil spill in November 2002 found that bacterial abundance did not change but bacterial activity was significantly enhanced, especially during winter and summer, compared to data obtained before the spill.
Microbial degradation of hydrocarbons in the environment.
Rates of biodegradation depend greatly on the composition, state, and concentration of the oil or hydrocarbons, with dispersion and emulsification enhancing rates in aquatic systems and absorption by soil particulates being the key feature of terrestrial ecosystems.
Relation between Bioavailability and Fuel Oil Hydrocarbon Composition in Contaminated Soils
Bioavailability of oil components in contaminated soils is an important regulating factor for biodegradation rates. Changes in the composition of mineral oil can provide information regarding the
