This study utilized the electrocatalytic characteristics of nickel electrode to perform degradation of methyl tert-butyl ether (MTBE) in aqueous solution. Lab experiments were conducted in a spiltless bath type cell equipped with a nickel electrode as working electrode, a platinum wire as counter electrode, and an Ag/AgCl electrode as reference electrode. Effects of controlled potential, suppor...

Methyl-t-butylether (MTBE) is a synthetic ether that is mainly used as a fuel additive: it replaces lead in gasoline, increasing the anti-knock rating. Next to this it serves as an intermediate in the production of isobutylene and as a process solvent in the pharmaceutical industry. In clinical practice MTBE is used to dissolve gallstones. At room temperature MTBE is a colourless liquid with a ...

Among the few bacteria known to utilize methyl tert-butyl ether (MTBE) as a sole carbon source, Methylibium petroleiphilum PM1 is a well-characterized organism with a sequenced genome; however, knowledge of the genetic regulation of its MTBE degradation pathway is limited. We investigated the role of a putative transcriptional activator gene, mdpC, in the induction of MTBE-degradation genes mdp...

Cells of Mycobacterium vaccae were grown in toluene, ethanol, methyl tert-butyl ether (MTBE) and glycerol, exhibiting different degrees of tolerance towards these compounds, and being able to use both ethanol and glycerol as sole carbon and energy sources. Cellular adaptation to ethanol and MTBE led to significant changes in the membrane fatty acid (FA) composition, by modifications in the prop...

Methyl tertiary-butyl ether (MTBE) is used to reduce carbon monoxide and ozone in urban air and to boost fuel octane. There is a lack of knowledge in the literature about the histomorphometric changes of the testis following exposure to MTBE. Therefore, this experimental study was performed to determine the effect of oral exposure to MTBE on histologic and histomorphometric changes of testis in...

Methyl tertiary butyl ether (MTBE) is an oxygenated fuel additive which has been used widely in many parts of the world. This experiment was performed to determine the effect of MTBE on offspring sex ratio, sex hormones and antioxidant enzymes. A total of 20 adult Sprague-Dawley male rats were divided into four groups and received 0, 400, 800 and 1600 mg/kg/day MTBE by gavages for 30 consecutiv...

Widespread contamination of groundwater by methyl tertiary butyl ether (MTBE) has triggered the exploration of different technologies for in situ removal of the pollutant, including biostimulation of naturally occurring microbial communities or bioaugmentation with specific microbial strains known to biodegrade the oxygenate. After laboratory studies revealed that bacterial strain PM1 rapidly a...

Methyl tertiary-butyl ether (MTBE) is a synthetic solvent widely used as oxygenate in unleaded gasoline. Few studies have addressed the cellular toxicity of MTBE on some cell lines, and so far, no comprehensive study has been conducted to investigate the probable immunotoxicity of this compound. In this study, the toxicity of MTBE on human blood lymphocytes was evaluated. Blood lymphocytes were...

mtbe (methyl tertiary-butyl ether) is an oxygenated organic matter which is widely used nowadays in some countries in unleaded gasoline. mtbe is a toxic substance which is absorbed quickly on water and soil and is one of the most important pollutants in soils and groundwater resources. in order to remove mtbe from the soil, using different experimental methods, determining reliable methods for ...
