Increased energy demand and the concern about environment friendly technology, renewable bio-fuels are better alternative to petroleum products. In the present study linseed oil was used as alternative source for diesel engine fuel and the results were compared with baseline data of neat diesel. Performance parameters such as brake thermal efficiency (BTE) and brake specific fuel consumption (B...

background and objectives: petroleum hydrocarbons are harmful to the environment, human health, and all other living creatures. oil and its byproducts in contact with water block sunshine to phytoplanktons and thus break the food chain and damage the marine food source. this study aims to isolate the crude oil degrading and biosurfactant producing bacteria from the oil contaminated soils of gac...

Many industrial fermentations use complex medium containing both carbohydrate and oils as their carbon sources. Oil supplements have been shown to increase the antibiotic titre and are a cheaper alternative carbon source, in terms of carbon per unit volume, when compared to carbohydrates. Oil supplements are also preferred on an energy supply basis and have natural antifoam properties. The majo...

The fungi strains were tested in Bioscreen automated system to select the best nutritional source. Following, shaking submserse cultures were studied in media containing sole carbon or nitrogen source. The growth of these strains improved in media containing vegetable oil, with high concentration of lipids. The high concentration of γ-linolenic acid was obtained with M. circinelloides in cultur...

Piper hispidinervum (C. DC.), Piperaceae, is a promising source of sassafras oil, the source of safrol, currently derived from endangered plants of the Lauraceae such as Ocotea pretios Ness (Mez.), Cinamomum petrophilum, C. mollissimum, and Sassafras albidum Nutt. The essential oil of P. hispidinervum contains high levels (83–93%) of safrole in leaves which can be easily extracted by hydrodisti...

the effects of nitrogen (n) and phosphate (p) concentrations and temperature on crude oil biodegradation by two bacterial strains pg01 and pg02, previously isolated from persian gulf, were assessed. in order to determine the optimum concentration of n and p sources and temperature for oil consumption by the isolates, bacteria were cultured in 100 ml agitating culture flasks containing mineral s...

The oil palm, Elaeis guineensis, is the source of palm oil – the ‘tropical golden oil’. Malaysia is the world’s largest exporter of this golden oil. Palm oil is a versatile oil with a wide range of uses in food and nonfood areas. Triglycerides constitute the major component of crude palm oil, with smaller proportions of diglycerides and monoglycerides. The oil also contains other minor constitu...

Energy consumption has been essential to societies; because societies depend on the rising provisions of energy to meet their requirements for goods and services and endorse sustainable development. The major source of energy nowadays is oil; oil consumption is dependent on oil availability, production and price. Several Arab countries are considered as major suppliers of oil in the world; cons...

Knowledge of the spatial distribution of oil thickness patterns within an on-water spill is of obvious importance for immediate spill response activities as well as for subsequent evaluation of the spill impacts. For long-lasting continuous spills like the 2010 3-month Deepwater Horizon (DWH) event in the Gulf of Mexico, it is also important to identify changes in the dominant oil features thro...

Crude oil is the major source of energy worldwide being exploited as a source of economy, including Oman. As the price of crude oil increases and crude oil reserves collapse, exploitation of oil resources in mature reservoirs is essential for meeting future energy demands. As conventional recovery methods currently used have become less efficient for the needs, there is a continuous demand of d...
