English term or phrase: geosmin
Definition from Merriam-Webster dictionary:
a volatile, organic compound C12H22O that is formed especially by soil-dwelling bacteria (such as streptomyces) and aquatic cyanobacteria and that may contribute to the earthy, pleasant odor of petrichor or impart a disagreeable, musty taste and odor to drinking water and certain fish

Example sentence(s):
  • To put that in context, a shark can smell blood at one part per million. That means human noses are 200,000X more sensitive to geosmin, which is also the source of the earthy taste in some vegetables, than a shark is to blood. American Council on Science and Health
  • They came up with the idea of “olfactogenetics.” It’s similar in principle to optogenetics, an approach Potter had been trying with Drosophila but to underwhelming results. Rather than using light to stimulate a specific neuron, olfactogenetics uses an odor—geosmin. nature
  • Yet despite this substantial body of knowledge, geosmin and 2-MIB remain poorly understood throughout much of the water industry, and misconceptions which impede the prediction, treatment, and control of these volatile organic compounds (VOCs) persist. ASM Journals

Definition from Wikipedia:
Geosmin (z řeckého γεω- "země" a ὀσμή "vůně") je organická sloučenina typicky zemité vůně a chuti, produkovaná některými druhy aktinobakterií a zodpovědná za zemitou chuť červené řepy. Také se podílí na pronikavé vůni, která se objevuje, pokud prší po delším období sucha (tzv. vůně petrichor), nebo při narušení svrchní vrstvy půdy.

Example sentence(s):
  • Jak upozorňuje web o přírodě, životním prostředí a ekologii Ekolist, geosmin vytváří některé bakterie, například rod streptomyces, a uvolňují jej. - Czech Radio website  
  • Podmanivou vůni deště způsobuje organická sloučenina geosmin, kterou produkují některé druhy bakterií, například rod Streptomyces. - Pocitame s vodou
