Functional Amyloids Composed of Phenol Soluble Modulins Stabilize Staphylococcus aureus Biofilms
Figure 2
S. aureus produces extracellular fibers during biofilm growth in PNG media.
TEM micrographs of cells from S. aureus SH1000 biofilms grown in TSBg medium (A) versus cells from biofilms grown in PNG media (B). High magnification reveals fibers are associated with the cell wall and approximately 12 nm in width (C). An agr mutant does not produce extracellular fibers (D). Bar length indicates 1 µm in A, B, and D, and 250 nm in C.
