Absorption spectra of prodigiosin and norprodigiosin from FS14 and the FS14ΔPigF mutant. (a) The colour change of the products between FS14 and FS14ΔPigF. (b) The maximum absorption wavelength of prodigiosin from FS14-pMTKQS (cyan), the complementary strain FS14ΔPigF-pMTKQS-pigF (red) and the overexpression strain FS14-pMTKQS-pigF (blue) and of norprodigiosin from FS14ΔPigF-pMTKQS (orange).
