Gram-positive cells show up purple when the staining procedure is finished, while gram-negative cells show up pink. Crystal violet is used as the main stain in the gram stain.
Which color might you anticipate following a Gram stain?
A Gram stain has a purple color. When the dye and bacteria interact, the bacteria in a sample either remain purple or transform to pink or red. If the bacteria remain purple, they are Gram-positive. If the bacteria become pink or crimson, they are Gram-negative.
After staining, what color are gram-positive cells?
Peptidoglycan, which is found in gram-positive bacteria's cell walls in thick layers, is a component of the cell walls of many bacteria. In gram-positive bacteria, the peptidoglycan makes up around 90% of the cell wall. They emerge as a result of this.
