The potential biodegradation of crude oil was assessed based on the development of a fermentative process with a strain of Pseudomonas aeruginosa which produced 15.4 g/L rhamnolipids when cultured in a basal mineral medium using glycerol as a sole carbon source. However, neither cell growth nor rhamnolipid production was observed in the comparative culture system using crude oil as the sole car...

Taking into consideration both shipping and pipeline transport, this paper first analysed the risk factors for different modes of crude oil import transportation. Then, based on the minimum of both transportation cost and overall risk, a multi-objective programming model was established to optimize the transportation network of crude oil import, and the genetic algorithm and ant colony algorith...

Crude oil is a complex mixture mainly composed of various saturated and aromatic hydrocarbons. Whereas degradation of hydrocarbons by oxygen-respiring microorganisms has been known for nearly one century, utilization of hydrocarbons under anoxic conditions has been investigated only during the past ten years. The present paper summarizes investigations into the anaerobic degradability of crude ...

Egg surface applications of microliter quantities of crude and refined oils of high aromatic content are embryotoxic to mallards (Anas platyrhynchos) and other avian species; applications of aliphatic hydrocarbons have virtually no effect. Mallard eggs at 72 h of development were exposed to a mixture of aromatic hydrocarbons or to aromatic compounds representative to those present in crude oil ...

Previous studies indicate that crude oil leads to increased pigmentation and erythema (sunburn) in response to sunlight in exposed individuals. However, no information is currently available concerning whether crude oil exposure might enhance the immunosuppressive effects of solar ultraviolet radiation (UVR) on the skin. In order to address this question, the back skin of shaved, female C3H/HeN...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

Background: Crude oil is a very toxic chemical. Recently, the search for protective substances is attracting attention. This study aimed to investigate the hematoprotective potentials of oil palm leaves against the toxicity induced by crude oil. Methods: Male Wistar albino rats (n=36) were divided into six groups of rats (n=6). Group 1 (controls) were fed with normal rat food.  Groups 2 and ...
