2.3A: The Gram-Positive Cell Wall - Biology LibreTexts
WebUp to 90 percent of the cell-wall in Gram-positive bacteria is composed of peptidoglycan, and most of the rest is composed of acidic substances called teichoic acids. Teichoic acids may be covalently linked to lipids in the plasma membrane to form lipoteichoic acids. Lipoteichoic acids anchor the cell wall to the cell membrane. WebThe thickness and composition of the cell wall affects the outcome of Gram staining. Gram-positive bacteria have a thicker peptidoglycan layer and stain a purple or blue color due to the retention of the crystal violet stain used in the Gram stain protocol. In contrast, Gram-negative bacteria have a thinner peptidoglycan layer and an outer ... WebFeb 13, 2024 · The Gram-positive cell wall has a an extensive amount of peptidoglycan … methodz boston breach
