What is the difference between the cell wall of Gram positive and gram-negative bacteria?
What is the difference between the cell wall of Gram positive and gram-negative bacteria? Gram-negative bacteria are surrounded by a thin peptidoglycan cell wall, which itself is surrounded by an outer membrane containing lipopolysaccharide. Gram-positive bacteria lack an outer membrane but are surrounded by layers of peptidoglycan many times thicker than is found in the Gram-negatives. What is the main difference between the cell walls of gram positive and gram-negative bacteria quizlet? Gram positive bacteria have a thick peptidoglycan layer and no outer lipid membrane whilst Gram negative bacteria have a thin peptidoglycan layer and have an outer lipid membrane....
