Oil spills from pipeline ruptures are a major source of terrestrial petroleum pollution in cold regions. However, our knowledge of the bacterial response to crude oil contamination in cold regions remains to be further expanded, especially in terms of community shifts and potential development of hydrocarbon degraders. In this study we investigated changes of microbial diversity, population siz...

BACKGROUND Mangroves are transitional coastal ecosystems in tropical and sub-tropical regions and represent biologically important and productive ecosystems. Despite their great ecological and economic importance, mangroves are often situated in areas of high anthropogenic influence, being exposed to pollutants, such as those released by oil spills. METHODOLOGY/PRINCIPAL FINDINGS A microcosm ...

The worldwide increasing recourse to chemical dispersants to deal with oil spills in marine coastal ecosystems is a controversial issue. Yet, there exists no adequate methodology that can provide reliable predictions of how oil and dispersant-treated oil can affect relevant organism or population-level performance. The primary objective of the present study was to examine and compare the effect...

Brazilian offshore crude oil exploration has increased after the discovery of new reservoirs in the region known as pré-sal, in a depth of 7.000 m under the water surface. Oceanic islands near these areas represent sensitive environments, where changes in microbial communities due oil contamination could stand for the loss of metabolic functions, with catastrophic effects to the soil services p...

Soil contamination by used lubricating oil from automobiles is a growing concern in many countries, especially in Asian and African continents. Phytoremediation of this polluted soil with non-edible plant like Jatropha curcas offers an environmental friendly and cost-effective method for remediating the polluted soil. In this study, phytoremediation of soil contaminated with 2.5 and 1% (w/w) wa...

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 Deepwater Horizon accident has brought oil contamination of deep-sea environments to worldwide attention. The risk for new deep-sea spills is not expected to decrease in the future, as political pressure mounts to access deep-water fossil reserves, and poorly tested technologies are used to access oil. This also applies to the response to oil-contamination events, with bioremediation the on...

We report a case of Vibrio parahaemolyticus panophthalmitis which resulted from contamination of a wound with water from a pond in inland Georgia. The pond was on the property of an oil refinery which receives crude oil from southern Mississippi. Cultures of the pond water 5 years later did not yield V. parahaemolyticus, but did yield non-O1 V. cholerae and had 0.28% sodium chloride content. V....

There is at present considerable agitation in the country over the adulteration of mustard oil with argemone oil. It has been fully realized that ingestion of mustard oil contaminated with argemone oil produces symptoms similar to those of epidemic dropsy. The experiments carried out in the field and the observations made by the various workers in this respect support the argemone contamination...

HFCI34a was selected for the alternative refrigerant for CFC12 because of its excellent properties like thermodynamics. But there were several problems like immiscibilitiy with oil to replace CFC12 by HFC134a. In order to solve these problems, we developed new polyol ester refrigeration oil which had good miscibility with HFC134a and excellent thermal stability and lubricity as well. To apply p...
