In microbiology, gram staining is an important test used because it can determine the presence of bacteria in a sample, as well as differentiate between the two distinct bacteria species, which are gram-positive and gram-negative bacteria.

Gram Staining technique is the most important and widely used microbiological differential staining technique. It categorizes bacteria according to their Gram character (Gram positive or Gram negative). Along with their staining characteristics, Gram Positive and Gram Negative bacteria differ from each other in various aspects which are listed below :

a staining technique for the preliminary identification of bacteria, in which a violet dye is applied, followed by a decolorizing agent and then a red dye. The cell walls of certain bacteria, to retain the first dye and appear violet, while those that lose it appear red

Violet stained gram-positive cocci and pink stained gram-negative rod-shaped bacteria. Gram-positive bacteria are bacteria that give a positive result in the Gram stain test. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-colored when seen through a microscope.

Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet.

The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with.
