What is applied during the differential stage of gram staining?
In all bacteria that are Gram stained all the steps are used. It isn't until the end that you will know if they are Gram+ or Gram-. In Gram staining, all bacterial cells take up the crystal violet.Iodine is then added; it acts as a mordant, a chemical that helps retain the stain in certain cells.Those structures that cannot retain crystal violet are decolorized with 95% ethanol or an ethanol- acetone solution, rinsed, and subsequently stained (counterstained) with safranin (red).Gram+ will be violet while Gram- will be red. The thick cell walls of Gram-positive bacteria retain such stains as the crystal violet-iodine dye in the cytoplasm. Gram- will not.
