E. coli is a gram negative bacteria, meaning that it has a cytoplasmic lipid membrane, a peptidoglycan layer, and a (LPS) lipopolysaccharide layer. As a result, e. coli stains a pink colour on a gram stain from the counterstain saffranin. Gram positives stain purple retain the crystal violet dye even after washed with a decolouring solution.
