To induce sporulation, organisms can be grown on triple sugar iron (TSI) agar, urea agar, or nu-trient agar containing 5 mg/L of manganese sulfate. On Gram-stained smears, spores appear clear because they do not retain the crystal violet or safranin. However, spores will stain with specific dyes such as malachite green that is forced into the spore using heat; the vegetative cell is then counterstained with safranin.
