Negative staining requires an acidic dye such as india ink or nigrosin. Cereus colonies are usually lecithinase positive and mannitol negative on myp agar. Cereus reaching 10 6 cells g. Since the surface of most bacterial cells is negatively charged the cell surface repels the stain. It is a gram positive rod shaped aerobic motile beta hemolytic bacterium found in soil and food. This means that the stain readily gives up a hydrogen ion proton and the chromophore of the dye becomes negatively charged.
