How is a capsule structured?
What is the structure and function of a capsule ? Function of capsule : Prevent the cell from desiccation and drying: capsular polysaccharide bind significant amount of water making cell resistant to drying. Protection: it protect from mechanical injury temperature drying etc. Attachment: capsule helps in attachment on the surface.
In comparison to their slime layer counterparts capsules are more structured and difficult to extract. An S-layer is a highly structured but separate structure. S-layers are glycoprotein-based structures that incorporate themselves into the cell wall and provide rigidity and protection to the cells.

Composition and structure. The bacterial capsule consists of three components. Therefore we can observe from the inside to the outside: S-layer capsule proper and mucous layer. The S-layer is the most attached to the bacterial cell wall. It consists of proteins and glycoproteins that can be assembled in dimers trimers and hexamers thus forming a protein network with aqueous pores useful for filtering certain substances.
Capsule. Capsule is 0.2┬Ám thick viscus layer firmly attached to the cell wall of some capsulated bacteria. If capsule is too thick it is known as slime. Slime layer are loosely attached to cell wall and can be lost on vigorous washing and on sub culture. Composition of capsule: 98% water and …
