Abstract
A process for treatment of aqueous effluents, for example, an aquifer, that contains at least methyl-tert-butyl ether (MTBE) or methyl-tert-amyl ether (TAME) so as to reduce the concentration of said ether is described, characterized in that aI-2562 bacterium is grown under aerobic conditions in the presence of a growth substrate that contains said ether, and said ether is degraded by said bacterium down to the final degradation products, carbon dioxide and water. The results are improved in the presence of yeast extract.
