Fig. 4From: Putative metabolic pathway for the bioproduction of bikaverin and intermediates thereof in the wild Fusarium oxysporum LCP531 strainAbsorbance spectra of the naphthoquinone pigments a bikaverin 1 and bikaverin intermediates: b norbikaverin 2, c oxo-pre-bikaverin 3, d me-oxo-pre-bikaverin 4, e dinor-bikaverin 5, and f pre-bikaverin 6, isolated in intracellular extracts of F. oxysporum LCP531. Numbers and retention time (Rt.; in min.) are referring to the compounds identified on Figs. 2 and 3. Colors on graphs are referring to the red or yellow pigments isolated and identified in this studyBack to article page
