Field evaluations of marine oil spill bioremediation.
Bioremediation is defined as the act of adding or improving the availability of materials (e.g., nutrients, microorganisms, or oxygen) to contaminated environments to cause an acceleration of natural biodegradative processes. The results of field experiments and trials following actual spill incidents have been reviewed to evaluate the feasibility of this approach as a treatment for oil contami...
متن کاملBioremediation of Oil Spill
At present, petroleum hydrocarbon is one of the most serious Abstract: environmental problem. Oil spill occurring accidently in the ocean during transportation or other working places like refineries causes great threat to the flora and fauna existing nearby. Modern methods of remediation such as incineration, land filling, burning, etc. are expensive as well as their byproducts produced are of...
متن کاملMicrobial population changes during bioremediation of an experimental oil spill.
Three crude oil bioremediation techniques were applied in a randomized block field experiment simulating a coastal oil spill. Four treatments (no oil control, oil alone, oil plus nutrients, and oil plus nutrients plus an indigenous inoculum) were applied. In situ microbial community structures were monitored by phospholipid fatty acid (PLFA) analysis and 16S rDNA PCR-denaturing gradient gel ele...
متن کاملBioremediation of oil by marine microbial mats.
Cyanobacterial mats developing in oil-contaminated sabkhas along the African coasts of the Gulf of Suez and in the pristine Solar Lake, Sinai, were collected for laboratory studies. Samples of both mats showed efficient degradation of crude oil in the light, followed by development of an intense bloom of Phormidium spp. and Oscillatoria spp. Isolated cyanobacterial strains, however, did not deg...
متن کاملEffective bioremediation strategy for rapid in situ cleanup of anoxic marine sediments in mesocosm oil spill simulation
The purpose of present study was the simulation of an oil spill accompanied by burial of significant amount of petroleum hydrocarbons (PHs) in coastal sediments. Approximately 1000 kg of sediments collected in Messina harbor were spiked with Bunker C furnace fuel oil (6500 ppm). The rapid consumption of oxygen by aerobic heterotrophs created highly reduced conditions in the sediments with subse...
