Genes involved in fatty acids biosynthesis, modification and oil body formation are expected to be conserved in structure and function in different plant species. However, significant differences in the composition of fatty acids and total oil contents in seeds have been observed in different plant species. Comparative genomics was performed on 261 genes involved in fatty acids biosynthesis, TA...

Polymorphum gilvum SL003B-26A1(T) is the type strain of a novel species in the recently published novel genus Polymorphum isolated from saline soil contaminated with crude oil. It is capable of using crude oil as the sole carbon and energy source and can adapt to saline soil at a temperature of 45°C. The Polymorphum gilvum genome provides a genetic basis for understanding how the strain could d...

Iodine value (IV) is used as a parameter in process control as well as a quality parameter in traded palm oil products. IV measures the number of double bonds in the molecular structure of an oil. To form a double bond, carbon requires more energy (615 kJ/mol) than to form a single bond (350 kJ/mol). Therefore, the thermal behavior of an oil could reflect its iodine value. This study was conduc...

The bioavailability of organic contaminants to the degrading bacteria is a major limitation to efficient bioremediation of sites contaminated with hydrophobic pollutants. Such limitation of bioavailability can be overcome by steady-state biofilm-based reactor. The aim of this study was to examine the effect of such multicellular aggregation by naturally existing oil-degrading bacteria on crude ...

BACKGROUND Natural oil seeps offer the opportunity to study the adaptation of ecosystems and the associated microbiota to long-term oil exposure. In the current study, we investigated a land-to-sea transition ecosystem called "Keri Lake" in Zakynthos Island, Greece. This ecosystem is unique due to asphalt oil springs found at several sites, a phenomenon already reported 2500 years ago. Sediment...

A field-scale experiment with a complete randomized block design was performed to study the degradation of buried oil on a shoreline over a period of almost 1 year. The following four treatments were examined in three replicate blocks: two levels of fertilizer treatment of oil-treated plots, one receiving a weekly application of liquid fertilizer and the other treated with a slow-release fertil...

the chemical composition of the essential oil of fruits of pimpinella haussknechtiiboiss.was studied by gc-ms. after gc-ms analysis, one unknown component (56.7%) was observed, which was not characterized in the gc-ms library. the essential oil of p.hauskenekhtii was injected to hplc using ymc-pak-sil column (250 × 20 mm) with gradient system of hexane (a), and hexane: ethyl acetate, 9:1 (b) to...

Pesticide residue analysis in citrus oils is very important for their quality and marketing. This study assessed the reliability and sensitivity of enzyme-linked immunosorbent assays (ELISA) for simazine and cypermethrin screening in orange oil. Simazine was analyzed after extraction of the oil with methanolic phosphate buffer with a limit of quantitation (LOQ) of 40 microg/L for 1-fold and app...

The volatility of oil revenues in rentier countries, due to the large share of oil revenue in their economies, affects many variables. Oil revenues can also affect social behavior and culture. Therefore, social capital, as the result of social networks and institutions, can be directly and indirectly affected by oil rents. The review of economic literature suggests that oil revenues could poten...

BACKGROUND Soybean oil lipid emulsion may compromise immune function and promote hepatic damage due to its composition of long-chain fatty acids, phytosterols, high proportion of ω-6 fatty acids, and low α-tocopherol levels. Combination lipid emulsions have been developed using medium-chain triglyceride oil, fish oil, and/or olive oil, which provide adequate essential fatty acids, a smaller con...
