GEOSMIN Chemical Properties, Uses, Production
Description
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.
Uses
Geosmin is an earthly odorant resposible for the strong scent (petrichor) that occurs in the air when rain falls after a dry spell of weather or when soil is disturbed.
Uses

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