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 INFLUENTA FACTORILOR DE MEDIU ASUPRA DEZ:
Actinomicetele

Actinomicete sunt bacterii filamentoase, aerobice care formează un miceliu ramificat superficial similar cu cele ale ciupercilor.
...
Speciile din genul Streptomyces sunt foarte predominante în sol, în cazul în care acestea pot degrada o gamă largă de substraturi organice complexe prin enzime extracelulare. O caracteristică este faptul că oferă solului un miros stătut datorat producţiei unui compus organic volatil numit geosmin.

Example sentence(s):

Bacteriile sunt extrem de comune și pot fi găsite în zone din întreaga lume, ceea ce explică universalitate acestui dulce miros al ploii. Există păreri care susțin că mirosul nu ar fi cauzat doar de spori, ci de reacția cu substanța chimică secretată în timpul producerii sporilor, numită geosmin. Acest geosmin este prezent în sfecla roșie și este responsabil pentru gustul de pământ. În plus, prezența geosminului în apă poate provoca un gust neplăcut, de noroi. - Ziarul de sănătate
Contribuția principală la formarea mirosului de ploaie este adusă de microorganismele solului, în principal actinomicete și cianobacterii. Când mor, inclusiv din cauza lipsei de umiditate, se eliberează substanța geosmin (geosmin), trans-1,10-dimetil-trans-9-decalol. - CARE ESTE NUMELE MIROSULUI DUPĂ PLOAIE.
