Cell Wall of Gram Positive and Gram Negative Bacteria

 

The cell wall of the bacterium GRAM - is formed by:

• Membrane

• Two lipid membranes, inner and outer

• Three phospholipid membranes

• Lipids

Gram + bacteria are made up of:

• 80% peptidoglycan

• 50% lipopolysaccharides

• 90% peptidoglycan

• 30% lipopolysaccharides
