Explanation

If lipopolysaccharides (LPS) did not appear in the wall of bacteria on staining, it would be known as Gram-positive bacteria. The Gram staining technique is a widely used method to differentiate bacteria into two broad groups: Gram-positive and Gram-negative. The staining process involves the application of crystal violet, iodine, alcohol, and safranin to bacterial cells. Gram-positive bacteria retain the crystal violet stain due to their thick peptidoglycan layer in the cell wall, which traps the dye. They appear purple under a microscope. Gram-positive bacteria generally lack or have low amounts of LPS in their cell walls.
