Molecular organization of bacterial membrane lipids in mixed systems-A comprehensive monolayer study combined with Grazing Incidence X-ray Diffraction and Brewster Angle Microscopy experiments

► Molecular organization of bacterial membrane lipids in mixed Langmuir monolayers. ► Favorable packing of phosphatidylethanolamine and phosphatidylglycerol at 1:1 ratio. ► Formation of highly ordered associates between the lipids in model system.
