HPLC analysis of pigments extracted from Rvi. gelatinosus strains. Pigments were extracted from the same number of cells of each strain except for the ∆bchE strain, which had a much greater BChl a content than the other strains. (A) ∆bchE. (B) ∆bchE∆acsF. (C) ∆bchE∆acsF::cycI. (D) ∆bchE∆acsF::cycI-ycf54. (E) ∆bchE∆acsF::acsFRs. (Inset) Retention times and Soret/Qy maxima of peaks were used to identify BChl a.
