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.

The semivolatile cyclic alcohols 2-methylisoborneol (MIB) and geosmin (GSM) impart muddy or musty flavors to water and food products. A rapid quantitative analytical technique has been developed whereby microwave distillation is used to remove the volatile organic compounds from a

Streptomycetes are high G+C Gram-positive, antibiotic-producing, mycelial soil bacteria. The 8.7-Mb Streptomyces coelicolor genome was previously sequenced by using an ordered library of Supercos-1 clones. Here, we describe an efficient procedure for creating precise gene replacements in the cosmid clones
