In Gram-positive bacteria, the S-layer is attached to the peptidoglycan layer. Gram-negative bacteria's S-layer is attached directly to the outer membrane). Specific to Gram-positive bacteria is the presence of teichoic acids in the cell wall.

 Cell Wall Thickness Thick (20-80 nm) Thin (8-10 nm) Chemical Composition of Cell Wall Peptidoglycan, Teichoic acid Lipotechoic acid Lipopolysaccharide, Lipoproteins and Peptidoglycans Peptidoglycan Layer Thick (Multilayered) Thin (Single layered)Teichoic Acid in Cell Wall Present Absent
Lipopolysaccharide Layer (Outer Layer) Absent Present Lipid Content Absent or lower content of lipids than Gram Negative bacteria Contains higher content of lipids than Gram positive bacteria (due to presence of outer membrane) Porin Proteins Absent Present Flagellar Structure 2 rings in basal body 4 rings in basal body Periplasmic Space Absent Present
