Answer;
-May be lost from bacteria cultured in the lab
Step-by-step explanation;
- The S-layer is a surface paracrystalline layer that forms the outermost cell envelope covering the entire bacterial cell, and represents a predominant surface antigen, found in almost all archaea, as well as in many types of bacteria.
-Since S-layers are found in gram-positive and gram-negative bacteria and archaea, they can be associated with quite different supramolecular cell envelope structures. In gram-positive bacteria and archaea, the S-layer subunits are linked to the peptidoglycan-containing layer or to the pseudomurein.
