background: long-term extraction and production of various oil derivatives causes contamination of soil adjacent to production and refining area. the main important issue is the ecological hazard of these pollutants. the main aim of the study was to identify and separate native bacteria that are responsible for degradation of oil contaminated fields. methods: we prepared a compound sample of co...

The biological effects and expected fate of the vast amount of oil in the Gulf of Mexico from the Deepwater Horizon blowout are unknown owing to the depth and magnitude of this event. Here, we report that the dispersed hydrocarbon plume stimulated deep-sea indigenous γ-Proteobacteria that are closely related to known petroleum degraders. Hydrocarbon-degrading genes coincided with the concentrat...

Oil spills and petroleum based pollutions are very common which cause a potential threat to both terrestrial as well as aquatic life. Bioremediation has become an alternative way to remedy. These microorganisms can degrade a wide range of target constituents present in oil sludge. An ability to isolate high numbers of certain oil degrading microorganisms from an environment is commonly taken as...

background: hydrocarbons degradation is principally achieved by microorganisms in natural environments. the extent of hydrocarbons biodegradation is mainly conditioned by environmental factors and its success depends on the optimal condition for the crude oil degrading isolates. objectives: the aims of the current study was to isolate and identify crude oil degrading bacterium from surface sedi...

Background and Objectives: Bioaugmentation is a superior technique in bioremediation of contaminated soils with petroleum hydrocarbons. The aim of this study was to evaluate the effect of isolated bacteria from activated sludge of Asalouyeh special zone municipal wastewater treatment for bioaugmentation of kerosene-contaminated soils and to study the growth of isolated bacteria in the presence ...

Mangrove forests are coastal ecosystems that found worldwide in tropical and subtropical zones. Oil spill causes damage to these marine ecosystems. The objective of this study is study the oil-degrading bacteria in some mangrove forests that located at Persian Gulf. In this study sediments and plant materials were collected from mangrove forests at Persian Gulf (Minab and Khamir ports). Oil-deg...
