Cultivation of host-associated bacteria under sulfide-enriched microoxic and anoxic conditions

<p>Three images of cell colonies on culture plates inoculated with gill tissue homogenate from <em>Bathymodiolus brooksi</em>. The colonies grew under the following conditions: &nbsp;&nbsp;</p> <ul> <li>IMG_2467: microoxic, low H2S, low ammonium</li> <li>IMG_2468: microoxic, low H2S, low ammonium, organics</li> <li>IMG_2474: microoxic, low H2S, high ammonium, organics, 1 mM thiosulfate</li> </ul> <p>Image of a control plate without cultures inoculated with heat sterilized aliquot of <em>Bathymodiolus brooksi</em> gill homogenate:</p> <ul> <li>IMG_2475</li> </ul> <p>Two images of pH controls plated with homogenization medium that did not contain gill homogenate:</p> <ul> <li>IMG_2477: phenol red</li> <li>IMG_2479:&nbsp; bromothymol blue</li> </ul> <p>Two close up photos of colonies on agar plates</p> <ul> <li>IMG_2485</li> <li>IMG_2488</li> </ul>
