Effect of N and P fertilisation and aeration on biodegradation of crude oil in aged hydrocarbon contaminated soils

We conducted two laboratory experiments to examine the effects of fertilisation and agitation (aeration) on crude oil degradation in two soils with differential nutrient (nitrogen, phosphorus) availability. Two soils that had been spiked with crude oil two years before were mixed with nitrogen and/or phosphorus at three different levels and subsequently incubated 28 days (Exp. 1). In experiment...

the biodegradation of crude oil by bacillus subtilis isolated from contaminated soil in hot weather areas

using environmental-friendly methods in order to remove or reduce oil pollutants and their derivations in the environment are developing. in this study, the biodegrading ability of bacillus subtilis .sp which has been separated from oil-polluted soil was examined. it was revealed that it can reduce surface tension of growth medium and produce bio-surfactant at 37 and 20 degrees centigrade. also...

Effect of C/N Ratio on the Phytoremediation of Crude Oil Contaminated Soils by Puccinellia Distance

Petroleum contamination of soil is a serious problem throughout the oil producer countries. Vegetation may play an important role in the biodegradation of toxic organic chemicals in soil. For petroleum compounds, the presence of rhizosphere micro flora may accelerate biodegradation of the contaminants. In a greenhouse study, petroleum contaminated soil were treated using phytoremediation . ...

Statistical Optimization of Crude Oil Biodegradation by Marinobacter sp. Isolated from Qeshm Island, Iran

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 sed...
