Thiobacillus ferrooxidans, a facultative hydrogen oxidizer.
نویسندگان
چکیده
The type strain (ATCC 23270) and two other strains of Thiobacillus ferrooxidans were able to grow by hydrogen oxidation, a feature not recognized before. When cultivated on H2, a hydrogenase was induced and the strains were less extremely acidophilic than during growth on sulfidic ores. Cells of T. ferrooxidans grown on H2 and on ferrous iron showed 100% DNA homology. Hydrogen oxidation was not observed in eight other species of the genus Thiobacillus and in Leptospirillum ferrooxidans.

متن کاملSensitivity of Iron-Oxidizing Bacteria, Thiobacillus ferrooxidans and Leptospirillum ferrooxidans, to Bisulfite Ion.
When grown on iron-salt medium supplemented with the bisulfite ion, Leptospirillum ferrooxidans was much more sensitive to the ion than was Thiobacillus ferrooxidans. The causes of the sensitivity of L. ferrooxidans to the bisulfite ion were studied. The bisulfite ion completely inhibited the iron-oxidizing activities of L. ferrooxidans and T. ferrooxidans at 0.02 and 0.2 mM, respectively. A tr...
متن کاملProduction and Regeneration of Thiobacillus ferrooxidans Spheroplasts.
We investigated the production and regeneration of Thiobacillus ferrooxidans spheroplasts. Regeneration frequencies of up to 90% reversion were obtained. Attempts to transform T. ferrooxidans spheroplasts with a recombinant T. ferrooxidans plasmid were unsuccessful.
متن کاملDistribution of thiobacillus ferrooxidans and leptospirillum ferrooxidans: implications for generation of acid mine drainage
Although Thiobacillus ferrooxidans and Leptospirillum ferrooxidans are widely considered to be the microorganisms that control the rate of generation of acid mine drainage, little is known about their natural distribution and abundance. Fluorescence in situ hybridization studies showed that at Iron Mountain, California, T. ferrooxidans occurs in peripheral slime-based communities (at pH over 1....

A specific and very sensitive dot-immunobinding assay for the detection and enumeration of the bioleaching microorganism Thiobacillus ferrooxidans was developed. Nitrocellulose spotted with samples was incubated with polyclonal antisera against whole T. ferrooxidans cells and then in I-labeled protein A or I-labeled goat antirabbit immunoglobulin G; incubation was followed by autoradiography. S...
