Description

Crystal violet is the primary stain in Gram staining. It infiltrates the peptidoglycan-rich cell wall of Gram-positive bacteria, and forms entrapped complexes with Gram's iodine that retain the purple color post-decolorization. Thus, Gram-positive bacteria can be differentiated from Gram-negative bacteria whose peptidoglycan layer is considerably thinner.
