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. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process - s. epidermidis a gram-positve coccus - E. coli a gram-negative bacillus - C. xerosis a gram-positive bacillus How does each organism fulfill a specific niche based on the information provided above?arrow_forward
