Application
(±)-Geosmin has been used as a standard for GC-MS based analytical techniques. Geosmin has also been used to study its adsorption on activated carbon.
Biochem/physiol Actions
(±)-Geosmin is produced by Streptomyces coelicolor and cyanobacteria.
Geosmin is a naturally occurring biomolecule that contributes to the earthy or musty flavor and odor in water supplies. This water contaminant can be detected by humans at ng/l (parts per trillion) concentrations.
