Buried hydrocarbon deposits, such as liquid petroleum, represent an abundant source of reduced carbon for microbes. It is not surprising therefore that many organisms have adapted to an oily, anaerobic life deep underground, often at high temperatures and pressures, and that those organisms have had, and in some cases continue to have, an effect on the quality and recovery of the earth’s dimini...

BACKGROUND Patents have been granted for a number of techniques for petroleum biodegradation including use of micro-organisms for degradation of hydrocarbon-based substances and for hydrocarbon degradation in oil reservoirs, but there is a dearth of information on hydrocarbon degradation in different soil textures. OBJECTIVE Hence, this work investigated the effects of different soil textures...

In the United States, petroleum extraction, refinement, and transportation present countless opportunities for spillage mishaps. A method for rapid field appraisal and mapping of petroleum hydrocarbon-contaminated soils for environmental cleanup purposes would be useful. Visible near-infrared (VisNIR, 350-2500 nm) diffuse reflectance spectroscopy (DRS) is a rapid, nondestructive, proximal-sensi...

Aquamicrobium defluvii W13Z1 was isolated from petroleum-contaminated drill cuttings from the Bohai Sea and could degrade petroleum hydrocarbon with 5% NaCl at 15°C. Here, we present the 4.8-Mb draft genome sequence of this strain, which may provide useful information about the mechanism of petroleum degradation in drill cuttings.

Background:Several studies have reported the toxicological implications of inhalation of petroleum hydrocarbon fumes in animal models. But, there is certainly little or no documentation of the exposure to petroleum hydrocarbon fuel on oxidative stress levels in humans, unlike the pulmonary physiology. The present study was carried out to evaluate the effects of constituents of the hydrocarbon f...

Petroleum substances are the main source of pollutants stored in old waste pits. They cause degradation of biological life in the area of storage. The aim of this article is to present laboratory research on petroleum pollutant biodegradation. The hydrocarbon contaminants in old drilling wastes came from the Graby-19 waste pit. The tests included basic bioremediation and inoculation with a biop...

Petroleum hydrocarbon contamination of ground water is a significant and often complex problem. The complexity results from the fact that ground-water contamination is a product of soil contamination. Especially with older spills, significant amounts of hydrocarbons can be trapped below the water table. Traditional pump and treat is ineffective because of the low solubility of trapped oily phas...
