Bioremediation of Contaminated Sites
Bioremediation is a process in which microorganisms metabolize contaminants either through oxidative or reductive processes. Under favorable conditions, microorganisms can oxidatively degrade organic contaminants completely into non-toxic by-products such as carbon dioxide and water or organic acids and methane. Highly electrophilic compounds such as halogenated aliphatics and explosives typica...
متن کاملBioremediation of organic contaminated soils*
The term bioremediation covers a wide variety of engineered systems which utilize microorganisms to degrade, detoxify and immobilize organic contaminants. These systems include: l solid-phase treatment using unlined iand treatment systems or prepared bed bioreactors, l slurry-phase treatment systems completed either in-place or within tanks or impoundments, and l in situ treatment systems. Bior...
متن کاملEffect of Electrokinetic on Bioremediation of Disulfide Oil Contaminated Soil
The removal of disulfide oil (DSO) from contaminated soil was studied by the bioremediation method and the influence of electrokinetic on the bioremediation process was investigated. The bacillus subtilis strain was used in the bioremediation process. The effects of humidity, time and DSO concentration in soil was studied. The experimental results for the bioremediation of DSO show, the removal...
متن کاملEnhanced anoxic bioremediation of PAHs-contaminated sediment.
In this study, the biodegradation of 16 polycyclic aromatic hydrocarbons (PAHs) in marine sediment was investigated under three different anoxic conditions, i.e. sulfate-only, nitrate-only and mixed nitrate/sulfate as electron acceptors. All two-, three- and four-ring PAHs showed significant biodegradation with the removal efficiencies ranging from 42% to 77%, while five- and six-ring PAHs show...
متن کاملBioremediation of Herbicide-Contaminated Soil and Water
The contamination of soils, groundwater and surface waters by herbicides poses major clean-up problems. At present, the most common approach is containment, involving costly removal of highly contaminated soils to landfill sites. Bioremediation methods for in situ treatment are needed as alternative and/or supplementary approaches for cost-effective and residue-free clean-up. This project focus...
