    Definition "method of staining used to distinguish and classify bacterial species into two large groups by coloring these cells red (gram-negative) or violet (gram-positive)" Reference "COM-Terminology Coordination, based on: Monica Z. Bruckner, 'Gram Staining' (11.2.2020), Carleton College"
    Comment 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. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process.
