Title: Process for bacterial treatment of effluents that contain at least one ether

Abstract: A process for treating aqueous effluents that contain at least one ether, preferably ethyl tert-butyl ether (ETBE) and/or methyl tert-butyl ether (MTBE) and/or tert-amylmethylether (TAME) to reduce the concentration of said ether is described, characterized in that in the presence of a growth substrate, at least one bacterium that is selected from the group that is formed by Gordona terrae CIP I-1889 and Rhodococcus equi CIP I-2053 is grown in aerobic conditions, and the ether that is contained in the effluents is degraded in the presence of the substrate by the biomass of the bacteria that are thus produced.
