Availability of inorganic nutrients, particularly nitrogen and phosphorous, is often a primary control on crude oil hydrocarbon degradation in marine systems. Many studies have empirically determined optimum levels of inorganic N and P for stimulation of hydrocarbon degradation. Nevertheless, there is a paucity of information on fundamental kinetic parameters for nutrient enhanced crude oil bio...

Produced water (PW) and spent oil-based wastewaters are some of the largest mineral oil produced. Due to high toxicity hydrocarbons, several countries set stringent discharge limits its treatment is compulsory before discharge. In this work, biological coupled with production bacterial lipids demonstrated in sequential batch airlift reactors (SBAR). Two SBAR (2 L working volume) were used for P...

The diversity and degradation capacity of hydrocarbon-degrading consortia from surface deep waters the Eastern Mediterranean Sea were studied in time-series experiments. Microcosms set up ONR7a medium at situ temperatures 25 °C 14 for Surface Deep consortia, respectively, crude oil as sole source carbon. consortium was additionally investigated to allow direct comparison rates consortium. In to...

Marine hydrocarbonoclastic bacteria, like Alcanivorax borkumensis, play a globally important role in bioremediation of petroleum oil contamination in marine ecosystems. Accumulation of storage lipids, serving as endogenous carbon and energy sources during starvation periods, might be a potential adaptation mechanism for coping with nutrient limitation, which is a frequent stress factor challeng...

Large pilot scale bioremediation approaches were implemented for the treatments of oily sludge (OS) characterised by alkaline pH (pH > 9), high concentration metals (3% dry weight) and total petroleum hydrocarbons content (TPH) rangingbetween 22,000 67,300 mg kg ?1 from a Tunisian refinery. The included bioaugmentation biostimulation with autochthonous isolated bacterial strains consortia. Chem...
