  • Process for bacterial treatment of effluents that contain ethyl-tert-butyl ether
    Patent number: 6040154
    Abstract: A process for treating aqueous effluents that contain ethyl-tert-butyl ether (ETBE) to reduce the ETBE concentration is described, characterized in that in the presence of effluents, 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 and in the presence of at least one bacterium that is selected from the group that is formed by Pseudomonas cepacia CIP 1-2052, Arthrobacter globiformis ATCC 53596, Bacillus coagulans ATCC 53595, Pseudomonas stutzerii ATCC 53602 and Mycobacterium vaccae JOB5 are grown to degrade essentially all of the ETBE. The concentration of ETBE in the effluent is equal to at most 1500 mg/L. Application for the water treatment industry.
