Gram positive vs gram negative teichoic acid
WebThe wall is relatively thin and contains much less peptidoglycan than the Gram-positive wall. Also, teichoic acids are absent. …. In the Gram-negative Bacteria the cell wall is relatively thin (10 nanometers) and is composed of a single layer of peptidoglycan surrounded by an outer membrane. WebGram-positive bacteria also contain polysaccharides, lipoteichoic acid and teichoic acid in their walls. Gram-negative bacteria contain lipopolysaccharide, lipoprotein, and porin proteins. I chose to list the steps of staining the gram-positive bacteria of Bacillus anthracis. First you would take a smear sample onto a glass slide.
