Gas chromatography (GC), gas chromatography-mass spectrometry (GC/MS), supercritical fluid chromatography (SFC), elemental analysis, infrared absorption spectroscopy (IR), thermal analysis (TG/DTA), Rock-Eval pyrolysis, as well as viscosity and density analysis revealed that oil sands from Qaidam basin, Qinghai Province of China, are highly concentrated in light components (£C23), with saturate...
Structure of bacterial communities along a hydrocarbon contamination gradient in a coastal sediment.
The bacterial diversity of a chronically oil-polluted retention basin sediment located in the Berre lagoon (Etang-de-Berre, France) was investigated. This study combines chemical and molecular approaches in order to define how the in situ petroleum hydrocarbon contamination level affects the bacterial community structure of a subsurface sediment. Hydrocarbon content analysis clearly revealed a ...
This research investigated the effect of three different acids (sulphuric acid, hydrochloric acid and nitric acid), on three different clay deposit samples, to recycle used lubricating oil. To achieve this objective, filtration of the used oil was carried out first to remove impurities like: sand, metal chip and other micro impurities using: Buncher funnel, filter papers and vacuum pump. The fi...
During any marine oil spill, floating oil slicks that reach shorelines threaten a wide array of coastal habitats. To assess the presence of oil near shorelines during the Deepwater Horizon (DWH) oil spill, we scanned the library of Synthetic Aperture Radar (SAR) imagery collected during the event to determine which images intersected shorelines and appeared to contain oil. In total, 715 SAR ima...
The potential effects of three modern extraction technologies (cold-pressing, microwaves and subcritical fluids) on the recovery of oil from Chaenomelessinensis (Thouin) Koehne seeds have been evaluated and compared to those of conventional chemical extraction methods (Soxhlet extraction). This oil contains unsaturated fatty acids and polyphenols. Subcritical fluid extraction (SbFE) provided th...
BACKGROUND To investigate the effect of environmental factors such as light and shade on essential oil yield and morphological traits of Moroccan Myrtus communis, a chemometric study was conducted on 20 individuals growing under two contrasting light environments. RESULTS The study of individual's parameters by principal component analysis has shown that essential oil yield, altitude, and lea...
With the frequent occurrence of marine oil spill and the serious environmental pollution as well as enormous economic losses it causes, there is a growing demand for oil spill emergency response. It becomes a trend to research on spatial information analysis and publishing based on GIS. Compared with the expensive and system-huge commercial software, open source platform which is free and small...
UNLABELLED It is well known that the nutritional quality of the American oil-palm (Elaeis oleifera) mesocarp oil is superior to that of African oil-palm (Elaeis guineensis Jacq. Tenera) mesocarp oil. Therefore, it is of important to identify the genetic features for its superior value. This could be achieved through the genome sequencing of the oil-palm. However, the genome sequence is not avai...
Aromatic grasses of the genus Cymbopogon (Poaceae family) represent unique group of plants that produce diverse composition of monoterpene rich essential oils, which have great value in flavor, fragrance, cosmetic, and aromatherapy industries. Despite the commercial importance of these natural aromatic oils, their biosynthesis at the molecular level remains unexplored. As the first step toward ...
