A The molecular subnetwork of the tentatively identified PDA-DAG lipids. Pie charts shown in subnetwork are the same as nodes shown in Fig. 1, representing different lipid structures. The size of the pie charts represents the summed intensity of all the species using various electron acceptors. Colors of pie chart represents the fractional abundance of this lipid among all the Sulfurimonas species grown at various conditions. B PDA-DAG lipid structures and their fractional abundance of total PDA-DAGs found in subnetwork Fig. 3. C MS2 spectra of two PDA-DAGs that have the same elemental composition (EC of C42H80O8N2P+; m/z 771.5647) but differ in the size of the alkyl chains of the polar headgroup and the number of carbon atoms of the acyl moieties.
