PPT-Spore Stain : Spores represent a chemically and physically resistant form of the vegetative

refractile body within the vegetative cells Procedure fig10 1 Prepare a fixed smear 2 Flood the smear with 5 malachite green and let the stain react for 1 minute Using your bunsen burner heat the top of the stained slide until steam rises but do not let it boil This step is performed by passing the burner back and over the slide for about 5 minutes. . sp.
