Bacterial community structures were evaluated in oil samples using culture-independent pyrosequencing, including oil mousses collected on sea surface and salt marshes during the Deepwater Horizon oil spill, and oil deposited in sediments adjacent to the wellhead 1 year after the spill. Phylogenetic analysis suggested that Erythrobacter, Rhodovulum, Stappia, and Thalassospira of Alphaproteobacteria were the prevailing groups in the oil mousses, which may relate to high temperatures and strong irradiance in surface Gulf waters. In the mousse collected from the leaves of Spartina alterniflora, Vibrio of Gammaproteobacteria represented 57% of the total operational taxonomic units, suggesting that this indigenous genus is particularly responsive to the oil contamination in salt marshes. The bacterial communities in oil-contaminated sediments were highly diversified. The relatively high abundance of the Methylococcus, Methylobacter, Actinobacteria, Firmicutes, and Chlorofexi bacteria resembles those found in certain cold-seep sediments with gas hydrates. Bacterial communities in the overlying water of the oil-contaminated sediment were dominated by Ralstonia of Betaproteobacteria, which can degrade small aromatics, and Saccharophagus degradans of Gammaproteobacteria, a cellulose degrader, suggesting that overlying water was affected by the oil-contaminated sediments, possibly due to the dissolution of small aromatics and biosurfactants produced during biodegradation. Overall, these results provided key information needed to evaluate oil degradation in the region and develop future bioremediation strategies.

“…Two microorganisms with proved hydrocarbon-degrading potential, R. picketti BP20 and A. piechaudii KN1were used in the present study. Plaza and coauthors reported that co-culture of these strains removed 91% of TPH in oilcontaminated waste after 30 days incubation [17]. The initial TPH load in cultivation/degradation media was 1.9%.…”

Biodegradability of drilling fluid waste is essential in the development of environmentally compatible oil and gas drilling. Biodegradation is determined not only by the enzymatic potential, but also microbial tolerance to hydrocarbons. The present study investigated the hydrocarbon degradation and tolerance of Ralstonia pickettii BP20 and Alcaligenes piechandii KN1 to drilling fluids with diesel and low-aromatic continuous phases in respect to their state: non-emulsified oil, direct (O/W) and invert (W/O) emulsions; and the concentrations affecting microbial activity and viability. In general, A. piechaudii KN1demonstrated higher tolerance than R. picketti BP20 did; but, the impacts of different drilling fluids on viability and activity of both microbial strains had similar trends. Microbial growth and hydrocarbons degradation rates increased when diesel was replaced with low aromatic oil, and emulsified. The higher productivity was observed in direct (O/W) emulsions than in invert (W/O) emulsions. Similarly, viability of microorganisms in low aromatic fluids and emulsions was higher than in corresponding diesel drilling fluids. Tolerance to low aromatic fluids increased in the order: non-emulsifier oil < invert emulsion < direct emulsion. In contrast, for diesel based drilling fluids, direct emulsion enhanced, but invert emulsion reduced microbial viability compared to non-emulsified oil.

Crude oil is a complex mixture of hydrocarbons, basically composed of aliphatic, aromatic and asphaltene fractions along with nitrogen, sulfur and oxygen containing compounds. Major causes of oil contaminated soils include: leakage of storage tanks and pipelines, land disposal of petroleum wastes and accidental spills. Apart from damaging crops and affecting the fertility of soil, crude oil on the fi elds also affects livestock. The loss of soil fertility and toxicity of petroleum hydrocarbon at higher concentrations have been linked to displacement of nutrients and nutrient linkage, reduction in phosphorus and nitrogen availability, and anoxic conditions. Moreover, it can cause microbial community structure changes and a decrease in microbial diversity. The aromatics in crude oils such as a -pinene, limonene, camphene, and isobornyl acetate were observed to be inhibitory to the microorganisms. In recent years, there has been increasing interest in developing on site and in situ techniques for remediation of oil-contaminated soils. Bioremediation can be achieved by natural attenuation, biopiling, bioaugmentation, phytoremediation or rhizoremediation, singly or in combination. Numerous genera of bacteria are known as good hydrocarbon degraders. Most of them belong to Aeromonas, Alcaligenes, Acinetobacter, Arthobacter, Bacillus, Brevibacterium, Mycobacterium, Pseudomonas, Rhodococcus, Sphingomonas,
