Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملBiodegradation of Polychlorinated Biphenyls by and Isolated from Contaminated Soil
Polychlorinated biphenyls (PCBs) cause many significant ecological problems because of their low degradability, high harmfulness, and solid bioaccumulation.Two bacterial strains were isolated from soil that had been polluted with electrical transformer liquid for more than 40 years. The isolates were distinguished as Lysinibacillus macrolides DSM54Tand Bacillus firmus NBRC1530...
متن کاملEnhanced Biodegradation of Petroleum Hydrocarbons in Contaminated Soil
Soil samples taken from a contaminated site in Northern Quebec, Canada, exhibited a low capacity for biodegradation of total petroleum hydrocarbons (TPH), despite a high capacity for the mineralization of aromatic hydrocarbons and a low toxicity of soil leachates as measured by Microtox assay. Toxicity assays directly performed on surface soil, including earthworm mortality and barley seedling ...
متن کاملEnhanced Bio-Immobilization of Pb Contaminated Soil by Immobilized Bacteria with Biochar as Carrier
This paper examines the potential value of phosphate-solubilizing bacteria(PSB) in the dissolution of soil phosphorus and in the subsequent immobilization of lead (Pb), both in bacterial growth medium and in soil. In growth medium, Pseudomonas chlororaphis showed both phosphate-solubilizing and Pb-immobilizing capability, the immobilization of Pb was attributed to pyromorphite formation, as ind...
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...
