- Abstract
We studied biosynthesis of colored naphthoquinone metabolites by Fusarium decemcellulare, F. graminearum, and F. bulbigenum fungi. F. bulbigenum and F. graminearum synthesized bikaverin and aurofusarin, respectively, which depended on the conditions of cultivation. F. decemcellulare synthesized soluble extracellular naphthoquinones of the naphthazarin structure (javanicin, anhydrojavanicin, fusarubin, anhydrofusarubin, bostricoidin, and novarubin) or extracellular dimeric naphthoquinone aurofusarin. Biosynthesis of naphthoquinone pigments was shown to be the main fungal response to stress exposure. It occurs under conditions of growth inhibition or arrest.
