1. Hydrochloric acid and ethanol is used as decolorizer
2. Endospores are formed mainly in bacterias and are produced during adverse conditions. Parent cells use to produce it.
3. Endopores are stained green
4. Safranin, methylene blue, and malachite green basic stains. Carbolfuchsin is a mixture of phenol and basic fuchsin hence it is also basic
