Abstract

Acetylene reduction was observed with ferrous-iron-oxidizing Thiobacillus ferrooxidans, as expected from previous studies with this bacterium. Acetylene reduction was also found during the growth of T. ferrooxidans on tetrathionate. Only Leptospirillum ferrooxidans, one of several other phylogenetically diverse, ferrous-iron- and/or sulfur-oxidizing acidophilic microorganisms, also reduced acetylene. A reduction of the oxygen concentration in the culture atmosphere was necessary to alleviate inhibition of nitrogenase activity. DNA sequences homologous to nif structural genes were found in both organisms. Diazotrophic growth of L. ferrooxidans was inferred from an increase in iron oxidation in ammonium-free medium when the oxygen concentration was limited and from apparent inhibition by acetylene under these conditions.
