Gram Staining PPT: Definition, Procedure, Conditions and Risks

The crystal violet used to stain the cells of gram-positive bacteria is retained by the presence of a thick layer of peptidoglycan in their cell walls. In contrast, Gram negative bacteria stain red because their peptidoglycan walls are thinner and don’t hold on to the crystal violet during the decolorizing process, causing them to stain red. Three steps are involved in gramme staining: crystal violet staining, decolorization, and counterstaining, typically with safanin.
