Document Type and Number:

WIPO Patent Application WO/1999/042563

Kind Code:

Abstract:

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 $i(Candida), $i(Pichia) and $i(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.
