Capsules: - polysaccharide layer is generally referred to as a glycocalyx - the glycocalyx is the poly A. A capsule is a gelatinous outer layer secreted by bacterial cell and that surrounds and adheres to the cell wall. Endospore staining visualizes endospores in bacteria like Bacillus. Note that beginning microbiology students often confuse cells within capsules for endospores within vegetative cells. 211-212) Purpose: To learn the procedure for doing the capsular stain and observe capsules under the microscope. Endospores allow bacteria to survive harsh conditions and germinate later.
