Capsules and slime
Functions of capsule:
2. It protects the bacterial cell against desiccation as it is hygroscopic and contains water molecules. 3. It may survive in natural environment due to its sticky property. After attachment they can grow on diverse surfaces. E.g., root surfaces, of human teeth and tissues, rocks in fast growing stream etc. 4. They may inhibit the engulfment by white blood cells (WBC’s) and therefore contribute to virulence. 5. Protects the cell from desiccation, maintaines the viscosity and inhibit the movement of nutrient from the bacterial cell. 6. Acts as sources of energy for some bacterial species. |
