Abstract

A method for spectrophotometric determination of p-aminoacetophenone (p-AAP) in the mycelium and fermentation broth filtrates of organisms producing polyenic macrolide antibiotics is described. The level of p-AAP accumulation was studied as applicable to the biosynthesis of levorin, a polyenic antibiotic of the heptaen series. The levels of p-AAP under usual conditions of the levorin-producing organism cultivation and under conditions of its stimulation with the products of the vital activity of yeast-like fungi were compared. Higher levels of p-AAP in the cultures grown with stimulation of the antibiotic biosynthesis were noted. Inadequacy of the correlation between production of levorin and p-AAP is discussed.
