The endospore stain is a differential stain used to visualize bacterial endospores. Endospores are formed by a few genera of bacteria, such as Bacillus.By forming spores, bacteria can survive in hostile conditions. Spores are resistant to heat, dessication, chemicals, and radiation.he endospore stain is a differential stain used to visualize bacterial endospores.

1 Use Malachite Green and either steam or heat (ask your instructor for which) to stain for endospores. 2  Apply stain while keeping the slide and perhaps some paper wet for 10 minutes (add more stain to keep it wet). 3  If using Steam: 4  Place the slide(s) on a slide holder over steaming water. First, make a bacterial smear or smears of your Unknown species, let it air dry (do something else while waiting). 2  It is probably a good idea to make two smears of differing amounts of bacteria. 3  Heat fix the slides. 4  Use Malachite Green and either steam or heat (ask your instructor for which) to stain for endospores.
