Biochemical and Ecological Control of Geosmin and 2-Methylisoborneol in Source Waters

The majority of all biologically caused taste-and-odor outbreaks in drinking water characterized worldwide are caused by microbial production of (−)-geosmin [(−)-(4 S ,4a S ,8a R )-4,8a-dimethyloctahydronaphthalen-4a-ol] and (−)-2-methylisoborneol (2-MIB) {(1 R -exo)-1,2,7,7-tetramethylbicyclo
