The low number and activity of hydrocarbon-degrading bacteria and the low solubility and availability of hydrocarbons hamper bioremediation of oil-contaminated soils in arid deserts, thus bioremediation treatments that circumvent these limitations are required. We tested the effect of Ethylenediaminetetraacetic acid (EDTA) addition, at different concentrations (i.e. 0.1, 1 and 10 mM), on bacter...

We describe an assembled marine bacterial consortium designed for bioremediation of oil-contaminated seawater, based on a statistical method using Plackett-Burman (PB) experimental approach. The final consists four bacteria isolated from the Gulf Mexico, genera: Pseudomonas, Halopseudomonas, Paenarthrobacter , and Alcanivorax . Individually, oil removal by these microorganisms was evaluated gra...

Hydrocarbonoclastic bacteria (HCB) play a key role in the biodegradation of oil hydrocarbons in marine and other environments. A small number of taxa have been identified as obligate HCB, notably the Gammaproteobacterial genera Alcanivorax, Cycloclasticus, Marinobacter, Neptumonas, Oleiphilus, Oleispira, and Thalassolituus, as well as the Alphaproteobacterial genus Thalassospira. Detection of H...
