Gram negative and positive cell walls
WebJan 14, 2024 · One of the main differences between the cell wall of Gram-positive bacteria and Gram-negative bacteria is the absence of lipopolysaccharide (LPS) layer in the Gram-positive bacteria. The main … WebThe cell wall of gram-negative bacteria is thin (approximately only 10 nanometers in thickness), and is typically comprised of only two to five layers of peptidoglycan, depending on the growth stage. In gram-positive bacteria, the cell wall is much thicker (20 to 40 nanometers thick).
