Abstract
An iron-oxidizing bacterium has been isolated by conventional bacteriological methods from acidic leaching water of Bingham Canyon, Utah. Ferrous ion and sulfur provide energy for the growth of this bacterium and are oxidized by cell suspensions in manometric experiments. Carbon dioxide fixation was found to be 1 [mu]mole per 25 [mu]mole oxygen absorbed in growth experiments and 1 [mu]mole per 40 [mu]mole oxygen absorbed in cell suspension studies. The bacterium is not identical to either of 2 previously described iron-oxidizing bacteria, Thiobacillus ferroxidans or Ferrobacillus ferrooxidans.
