This detailed analysis explores a stained preparation of Bacillus subtilis, highlighting the distinct morphological differences between active vegetative cells and dormant endospores. By utilizing differential staining techniques, such as the Schaeffer-Fulton method, microbiologists can identify these resilient structures, which appear vibrant green against the pink backdrop of the bacterial cells. This visual distinction is crucial for understanding the survival mechanisms of specific Gram-positive bacteria in harsh environments.
