A Bacterial Outer Membrane is a Lipid Bilayer that forms the outermost layer of a Gram-Negative Bacteria's Cell Envelope.
- AKA: Outer Membrane, Cell Outer Membrane.
- Context:
- It includes a Lipopolysaccharide.
- See: Gram-Negative Bacteria, Cytoplasmic Membrane.

- The bacterial outer membrane is found in Gram-negative bacteria. Its composition is distinct from that of the cytoplasmic membrane - among other things, the outer leaflet of the membrane include a complex lipopolysaccharide whose lipid portion acts as an endotoxin - and it is linked to the cell's peptidoglycan by Braun's lipoprotein.
- Porins can be found in this layer. [1]

- Definition
- A lipid bilayer that forms the outermost layer of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures. [source: GOC:mtg_sensu, ISBN:0135712254]
