Oxygen consumption rates/zero valent iron dissolution of FeOB with kanamycin addition - replacement samples

<p>In these experiments, oxygen consumption rates were measured&nbsp;for the iron-oxidizing bacteria (FeOB)&nbsp;Mariprofundus ferrooxydans PV-1 as well as the neutrophilic 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 oxygen consumption at 100 uM oxygen at 20 degrees C. After 3 days the media in each vessel was replaced with fresh media containing kanamycin to stop any further growth and examine abiotic effects of iron mat production on zero valent iron dissolution.</p>
