Traditional remediation strategies include chemical, physico-chemical and thermal techniques, which are still widely used. Recommendations offered include encouraging asphalthene biodegradation by combining heat application (80C), biosurfactant (thermophilic emulsifier) and bioagumentation (using a consortium containing Bacillus lentus and Pleurotus tuberregium as members) but as a temporary measure, adopting the use of booms and skimmers and organic sorbents for water and land clean-up, respectively. For three field seasons, we examined the hexadecane, phenanthrene, and. The involvement of both governmental and non-governmental environmental institutions in sponsoring field studies in order to improve the reliability of bioremediation research. Bacterial bioreporters are versatile tools that can help to monitor the trend of the treatment, can substantially improve the systematic protocols, and have provided evidence for an inhibitory effect of high cell densities in the medium, in particular after 24h of the treatments. Bacteria and microbes break down the complex chemicals into simpler substances such as carbon dioxide and fatty acids etc. J. A method and system for one or more pollutants has been provided. The containment of a summertime oil spill requires rapid (within hours) deployment of a surrounding boom to be followed by vacuum pumping and physical removal. However, such compounds are not only toxic, but bacteria in oil spill bioremediation efforts are constrained by the However, more research on the factors influencing theabundance and productivity of oil-degrading anaerobes may need to be carried out. This is often followed by the mopping up of as much oil as possible using sheets of absorbent materials. bioremediation practices, more work is needed to enhance the efficiency [1] "BP Statistical Biotechnol. This paper. Individual microbial agents or mixed microbial consortia able to remediate these pollutants in marine environments have been identified, and the most relevant mechanisms of biodegradation of pollutants are characterised. fuel and fuel oils), in general bioremediation is a significantly more economic option to straight disposal, however it can take anything from 1 month to several months to carry out.
