The time course of production of odorous compounds, i.e. geosmin and oxolones, and of avermectins was determined during the cultivation of S. avermitilis in flasks, 1- and 50-L fermentors. The amount of the antibiotics and geosmin increased with increasing cultivation time. A correlation was found between the production of geosmin and the production of avermectins. The production of oxolones peaked on cultivation days 3–5 and then it dropped below a measurable level. This can be explained as being due to the inhibition of oxolone production by geosmin.
Během kultivace S. avermitilis v baňkách, 1- a 50-L fermentorech byl stanoven časový průběh produkce pachových látek, tj. geosminu a oxolonů, a avermektinů. Množství antibiotik a geosminů stoupalo s časem kultivace. Byla nalezena korelace mezi produkcí geosminu a produkcí avermektinů. Produkce oxolonů byla maximální po 3–5 dnech a pak poklesla pod měřitelnou úroveň. To lze připsat inhibici produkce oxolonů geosminem
