Abstract
One of the musty odour components in drinking water, (-)-geosmin was microb iologically degraded with the backwash water collected from a biological fi lter pilot plant at Lake Biwa (Japan) and activated sludge obtained from Se ndai City Sewerage Bureau; in this process the presence of ethanol was esse ntial for acceleration of the reaction. Four biodegradation products were d etected by gas chromatography, among which a dehydration product and an oxi dation product were identified by mass spectroscopic comparison with unambi guously synthesized authentic samples.
