Petroleum hydrocarbon extraction and measurement. Soil samples were picked 5 gram in the 0,2,6,14,27 days respectively. They were extracted in 20ml tetrachloride carbon on a mechanical shaker over 12h and finally sonicated for centrifugation,total petroleum hydrocarbon levels in the extract were analyzed by gas chromatography with flame ionization detection (GC/FID).Using a Despite decades of research, successful bioremediation of petroleum hydrocarbon-contaminated soil remains a challenge (Rahman et al., ). However, certain microorganisms have developed mechanisms to grow and thrive in oil-containing environments and play an important role in the treatment of this type of pollutant by degrading ://

Office of Research Thus in situ bioremediation of PAH derivatives can be improved by the augmentation of degrading microbial populations and by the increase of hydrocarbon bioavailability (Bardi et al., ).
Generally, the addition of nutrients is necessary to enhance the biotransformation of petroleum-related pollutants (Choi et al., ; Kim et al., Intrinsic Bioremediation of MTBE-Contaminated Groundwater at a Petroleum-Hydrocarbon Spill Site Article (PDF Available) in Environmental Geology 50(3) June with Reads for bioremediation of oil-spill contaminated sites.

Introduction of solid oxygen-releasing materials (e.g. calcium or magnesium peroxide) or direct delivery of oxygen gas into the barrier area is the most common method for promoting sustainable aerobic conditions for treatment of contaminants Bioremediation of benzene, toluene, ethylbenzene, xylenes-contaminated soil: A biopile pilot experiment Article (PDF Available) in Journal of Applied Microbiology (5) December This volume focuses on innovative bioremediation techniques and applications for the cleanup of contaminated media and sites.
It includes quantitative and design methods that elucidate the relationships among various operational parameters, and waste chemistry that defines the cost effectiveness of bioremediation :// Intrinsic bioremediation is believed to be the major process among the natural attenuation mechanisms that account for the reduction of contaminant concentrations.
In this study, a mass flux approach was used to calculate the contaminant mass reduction at a petroleum-hydrocarbon spill ://(ASCE)EE Abstract.
Much of the early work on the microbial utilization of petroleum hydrocarbons, conducted in the s and s, was done with the goal of using hydrocarbons as substrates for producing microbial biomass (Shennan, ; Champagnat, ; Champagnat and Llewelyn, ; Cooney et al., ; Ballerini, ).Petroleum was viewed as an inexpensive carbon source and single cell protein Specific challenges of in situ bioremediation: Bioremediation techniques have been tested in laboratories with good results but the transfer to the field has been often quite difficult (Sturman et al., ; Allard and Neilson, ).?doi=rjet For the preparation of soil extract and the enrichment of naphthalene- BTEX (benzene, toluene, ethyl benzene, and o- m- p-xylene)- and aliphatic hydrocarbon-degrading bacteria, soil Abstract.
Though several in-situ treatment methods exist to remediate polluted sites, selecting an appropriate site-specific remediation technology is challenging and is critical for successful clean up of polluted sites. Hence, a comprehensive overview of all the available remediation technologies to date is necessary to choose the right technology for an anticipated :// 2 days ago Crude oil is the world’s leading fuel source and is the lifeblood of the industrialized nations as it is vital to produce many everyday essentials.
This dependency on fossil fuels has resulted in serious environmental issues in recent times. Petroleum contaminated soils must be treated to ensure that human health and the environment remain :// Bioremediation is a viable mechanism for treating soils contaminated with petroleum hydrocarbons.
Bioremediation strategies range from encouraging natural biodegradation processes (biostimulation) to supplementing the existing system with microorganisms able to degrade the contamination (bioaugmentation) and to monitoring and verifying natural processes (natural attenuation).
Permeable reactive barriers (PRBs) technology has received a great deal of attention for in-situ groundwater bioremediation in past decades. In this regard, calcium peroxide (CaO 2) as an oxygen releasing compound (ORC) can slowly release oxygen and remediate hydrocarbon pollution by enhancement of the aerobic reactions in the subsurface ://.
