Description

(-)-geosmin is the (-)-stereoisomer of geosmin, having 4S,4aS,8aR configuration. It is an enantiomer of a (+)-geosmin.

Geosmin and other volatile compounds are produced by a variety of bacteria, cyanobacteria, algae, and fungi. They are responsible for some of the odors of water supplies and food sources. Odor production is greatest when nutrient production and dissolved oxygen are high.
