Thin peptidoglycan in cell wall
WebApr 22, 2011 · T. pallidum is a Gram-negative bacteria consisting of an inner membrane, a thin peptidoglycan cell wall, and an outer membrane. It is very small in size with a length that ranges from 6 to 20 um and a diameter range of 18-20 um. T. pallidum is a member of the spirochete family which are characterized by their distinct helical shape. WebGram-positive bacteria have a thick peptidoglycan layer in their cell wall, which retains the crystal violet during Gram staining, resulting in a purple color. Gram-negative bacteria have a thin peptidoglycan layer which does not retain the crystal violet, so when safranin is added during the process, they stain red.

WebAug 26, 2024 · This molecule is unique to bacterial cell wall composition. Peptidoglycan is a polymer composed of double-sugars and amino acids (protein subunits). This molecule gives the cell wall rigidity and helps to … 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).
WebIn contrast, Gram- negative bacteria stain pink because the thin peptidoglycan layer cannot hold onto the dye and is washed away during the decolorization step. Overall, the differences in the cell wall structure between Gram-positive and Gram-negative bacteria have significant implications for their physiology, metabolism, and pathogenicity.
