    • The first dye is crystal violet and is fixed or mordanted in Gram positive bacteria by iodine.
    • After 7-10 days growth, colonies were fixed and stained with a solution containing 0.35% crystal violet in 35% ethanol.
    • The cells were fixed by methanol, stained by crystal violet, and the number of plaques was counted.
    • Each section was immersed for 1 min in an aqueous 0.01% solution of crystal violet that stained the thickened cells in the endocarp and the vascular tissue violet.
    • The cells were allowed to migrate for 5 hr; the migratory cells attached to the bottom surface of the membrane were stained with 0.1% crystal violet for 20 min at room temperature.

    • Such bacteria do not stain purple with crystal violet and are known as Gram-negative.
    • About 1 week later, the cultures were fixed with methanol and stained with crystal violet.
