Malachite Green is used for bacterial spore staining by Schaeffer and Fulton’s method. It can also be used as a simple stain for bacterial cells and in place of methyl green in the Pappenheim stain, when combined with Gram stain. In the Schaeffer and Fulton’s method, primary stain malachite green is forced into the spores by steaming the bacterial emulsion. Malachite green is water soluble and has low affinity for cellular material so, vegetative cells may be decolourized with water. Vegetative cells are then counterstained with Safranin. Spores may be located in the middle of the cell, at the end of the cell or between the end and middle of the cell. Spores may be spherical or elliptical.
