Why do some bacteria stain violet in the Gram stain and some do not The Gram negative bacteria have peptidoglycan on the outside of their cell walls Gram positive bacteria have less peptidoglycan with an outer membrane that covers the peptidoglycan Gram positive bacteria are shaped differently than Gram negative bacteria Gram positive bacteria are rod like and Gram negative are spherical The stain allows the visualization of these shapes Gram negative bacteria cause severe disease Gram positive bacteria are chemoheterotrophs and so can metabolize the gram stain Gram negative bacteria are authotrophs and need not metabolize the gram stain Gram positive bacteria have peptidoglycan on the outside of their cell walls Gram negative bacteria have less peptidoglycan with an outer membrane to cover the peptidoglycan
