Non-limiting nutritional conditions revealed a growth-associated erythromycin production with ammonium sulfate while the relation was growth-dissociated for ammonium nitrate. Feeding experiments suggested that the residual nitrate level might be the key regulatory element. A nitrate-induced glutamine synthetase pathway was postulated according to the nature and initial concentration of the ammonium salt.
