Fe(II) concentrations over time in iron oxidizing bacteria cultures.

<p>In these experiments, dissolved Fe(II) concentrations were measured over time&nbsp;for the neutrophilic iron-oxidizing bacterium (FeOB)&nbsp;Mariprofundus&nbsp;ferrooxydans&nbsp;PV-1 as well as the FeOB \"TAG-1\" (An isolate from hydrothermal vents in the Mid Atlantic ridge that has not yet been formally named. TAG simply refers to the TAG hydrothermal site from which this microbe was isolated.). These experiments measure how Fe(II) concentration changes over time in culture media at 100 µM oxygen at 20 degrees C by sampling daily for 5 days.</p>
