Description: Putative Leptothrix ochracea collected from site LL1 at Lava Cap Mine, Nevada Cty, CA. Phase-contrast light microscope image showing predominantly empty sheaths characteristic of L. ochracea superimposed on the corresponding epifluoresent image. Using a passive DNA stain, a few filaments of cells can be seen within the sheaths. The overall brown color of the sheath is due to iron (hydr)oxides.
