A study was conducted in 2010 to investigate the effects of crude oil contaminated soil on biomass accumulation inJatropha curcas seedlings in Asaba, Delta State, Nigeria. Oil levels used were 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0% w/w. The trial was arranged in a randomized complete block design with four replications and monitored for 12 weeks after transplanting. Results showed that contamination...

Rhizoremediation involves the breakdown of contaminants in soil resulting from microbial activity that is enhanced in the plant root zone. The objective of this study was to assess Australian native grasses for their ability to stimulate removal of aliphatic hydrocarbons from a mine site soil. Time-course pot experiments were conducted in a greenhouse with three grass species (Cymbopogon ambigu...

With the rapid development of the petroleum industry, a large number of oil contaminants leaked into the soil in the petrochemical complex areas, gas stations, automobile factory and other places, which resulted in serious soil contamination. Micro-Biological degradation of oil pollution was the focus of the present study. Many hydrocarbon-contaminated environments were characterized by low or ...

Millions of barrels of crude oil gushed freely from these wells, creating oil lakes in low-lying areas of the desert. Lakes were formed at more than 500 different locations, covering a total area initially estimated at 49 km. While the Kuwait Oil Company (KOC) has recovered 22.5 million barrels of the spilled crude; the remaining amount, is considered unrecoverable by standard methods. An estim...

Soil contamination by petroleum hydrocarbons is a global problem. Phytoremediation by plants and their associated microorganisms is a cost-effective strategy to degrade soil contaminants. In boreal regions the cool climate limits the efficiency of phytoremediation. The planting of oil-tolerant perennial crops, especially legumes, in oil-contaminated soil holds promise for great economic benefit...

The aim of the studies was to compare the composition of soil bacterial metabiomes originating from urbanized areas and areas con¬taminated with hydrocarbons with those from agricultural soil and forest soil obtained from a protected wild-life park area. It should be noted that hydrocarbons are everywhere therefore bacteria capable of their utilization are present in every soil type. In the hyd...

Over the past decades rapid growth in industrial and agricultural activities, waste disposal and etc., have significantly contributed to extensive soil contamination. Total petroleum hydrocarbons (TPHs) are one of the most common groups of persistent organic contaminants. To date, many developing countries like Iran have almost completely relinquished remediation of oil-polluted soils due to th...

The hydrogen peroxide treatment was able to remediate chlorophenols, polycyclic aromatic hydrocarbons, diesel and transformer oil contaminated soil. Chemical treatment of contaminants adsorbed in peat resulted in lower contaminants’ removal and required higher addition of chemicals than the treatment of contaminants in sand. The hydrogen peroxide treatment was found to be feasible for soil reme...

the objective of the study was to determine the effect of the process of natural bioremediation, and bioremediation supported by zb-01 microbiological preparation on the occurrence of collembola and araneae in conditions of soil contaminated by petroleum-derived substances. the studies were conducted in 2010-2012, in the area of the experiment station of the university of agriculture, near krak...

To degrade chrysene, a polycyclic aromatic hydrocarbon (PAH) found in crude oil contaminated soil by bioremediation the Polyporus sp. S133, a fungus collected from soil was used. Maximal degradation (86%) was obtained when Polyporus sp. S133 was incubated in 0.5% tween 80 for 30 days, as compared to 30% degradation rate without tween 80. Chrysene was indeed degraded by Polyporus sp. S133 throug...
