Volatile substances from actinomycetes: their role in the odor pollution of water.
TL;DR: Gas chromatography (G C) proved to be the method by which to show that the earthy odor was caused by a single chemical substance which was named geosmin, and to demonstrate the presence ofGeosmin in many actinomycete fermentation broths and isolate enough for structure determination.
