GramPositive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in GramStaining, which is traditionally used to quickly classify bacteria (Bacterium) into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial Cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test.
