Evidence of three-dimensional structuring of KG3-03 colonies.

<p>Whole colonies taken from HI agar plates were vapor fixed with osmium tetroxide and viewed by SEM as described previously <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0100890#pone.0100890-Grau2" target="_blank">[7]</a>. Panels: (A), KG3(R); (B) YJ016; (C), KG4(T); (D) KG3-17; (E, F) KG3-03. All scale bars equal 100 µm. Images in panels E and F are taken from the same colony. All images presented are representative of many images taken for several colonies of each strain. To achieve uniformity, brightness was increased somewhat for images in panels A, B, D and F, while it was decreased for the image in panel C. Contrast was not adjusted for any of the images.
