biodegradation of petroleum hydrocarbons in soil
biodegradation of petroleum hydrocarbons (20 g/kg dw soil) was investigated in 3 media, differing in the kind of petroleum fractions. in the laboratory experiments, during 5 months, the activities of petroleum hydrocarbon-degrading microorganisms and dehydrogenase activity of soil was determined. gas chromatographic analysis showed the biological decontaminations for gas oil, kerosene and synth...
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 کاملPetroleum Hydrocarbons And Chlorinated Hydrocarbons Differ In Their Potential For Vapor Intrusion
Response issued draft vapor intrusion guidance (EPA, 2002), which specifically states that it is not recommended for Subtitle I underground storage tank (UST) sites. EPA's Office of Underground Storage Tanks (OUST) is thus currently developing guidance to address petroleum vapor intrusion (PVI) at UST sites. In September 2009, OUST assembled experts in the field of vapor intrusion and petroleum...

EPA's Office of Underground Storage Tanks (OUST) is thus currently developing guidance to address petroleum vapor intrusion (PVI) at UST sites.

متن کاملBiodegradation of petroleum hydrocarbons in hypersaline environments
Literature on hydrocarbon degradation in extreme hypersaline media presents studies that point to a negative effect of salinity increase on hydrocarbonoclastic activity, while several others report an opposite tendency. Based on information available in the literature, we present a discussion on the reasons that justify these contrary results. Despite the fact that microbial ability to metaboli...
