What would be the expected out come of a
Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents.
Gram-positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with whereas Gram-negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process.
