The cell wall of &#039;&#039;L. acidophilus&#039;&#039; is interwoven with [[teichoic acid]]s and surface proteins, with anionic and neutral polysaccharides as well as an S-layer lining the exterior of the cell. The S-layer proteins of &#039;&#039;L. acidophilus&#039;&#039; have been shown to adhere to epithelial cells as well as mucus and other extracellular proteins. The S-layer is made of two structural domains. The C-terminal domain is responsible for cell wall anchoring, while the N-terminal domain is responsible for interacting with the cell environment, as well as S-layer self assembly. In the &#039;&#039;L. acidophilus&#039;&#039; species, the N-terminal region shows high amino acid variability along with low sequence homology (31-72%). However, the C-terminus shows low amino acid variability and high amino acid sequence homology (77-99%).&#039;&#039;L. acidophilus&#039;&#039; does not have any extracellular means of motion like a flagellum or pilli, and therefore is an immobile microbe.<br /> [[File:Lactobacillus acidophilus (259 09) Lactobacillus acidophilus (Döderlein bacillus).jpg|thumb|&#039;&#039;Lactobacillus acidophilus&#039;&#039; under microscope with dark light background.]]</div> FuzzyBot
