[Survey the possibility of biodegradability of methyl tert-butyl ether [MTBE] by isolated microorganisms of activated sludges in the aqueous solutions and effects of stimulator substances on biodegradation]

ABSTRACT

Introduction: Methyl tert-butyl ether [MTBE] has been incorporated in reformulated gasoline at concentrations up to 15% [vol] to replace lead tetraethyl in order to comply with the octane index and to reduce the polluting emissions in exhaust gases. This compound is water soluble [48,000 mg/L] and one of the most common pollutants of ground water and surface water. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern
