A method for degrading and treating ethanol contained in an exhaust gas by bringing the ethanol in the exhaust gas into contact with an ethanol- metabolizable microorganism carried on a support, and an apparatus therefor. Use of a microorganism selected from among those belonging to the genera Candida, Pichia and Hansenula as the ethanol-metabolizable microorganism makes it possible to provide a method and an apparatus whereby ethanol contained in an exhaust gas can be eliminated at a high rate and a stable treatment can be performed over a long period of time even at a high ethanol concentration and under high load.
L'invention concerne un procédé qui permet de dégrader et de traiter l'éthanol contenu dans un gaz d'échappement en mettant ledit éthanol en contact avec un micro-organisme capable de métaboliser l'éthanol, fixé sur un support, et le dispositif associé. En utilisant comme micro-organisme capable de métaboliser l'éthanol un micro-organisme choisi parmi ceux appartenant aux genres Candida, Pichia et Hansenula, on obtient un procédé et un dispositif qui permettent d'éliminer avec un bon rendement l'éthanol contenu dans un gaz d'échappement et d'effectuer un traitement stable sur une longue durée, même avec une concentration d'éthanol élevée et une forte charge.
