Relation of the iron oxidizer, Thiobacillus ferrooxidans, to thiosulfate.

Colmer, Arthur R. (Louisiana State University, Baton Rouge). Relation of the iron oxidizer, Thiobacillus ferrooxidans, to thiosulfate. J. Bacteriol. 83:761-765. 1962.-A restudy has been made of Thiobacillus ferrooxidans secured from the acid drainage of some northern West Virginia coal mines. Cultures isolated from ferrous iron agar and then subcultured for 85 consecutive transfers in thiosulfa...

Thiobacillus ferrooxidans, a facultative hydrogen oxidizer.

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...

Kinetics of Iron Oxidation by Thiobacillus ferrooxidans.

A statistical relationship between the rate of ferric ion production by a strain of Thiobacillus ferrooxidans and various levels of cell concentration, Fe concentration, Na concentration, and temperature was studied by a direct colorimetric method at 304 nm. The relationship was linear (90 to 93%), cross-product (3 to 4%), and quadratic (1 to 2%). The levels of cell concentration and Fe concent...

Facultative Iron-Oxidizing Bacterium, Thiobacillus ferrooxidans

Properties ofa heat-labile glucose transport system in Thiobacillusferrooxidans strain AP-44 were investigated with iron-grown cells. [14C]glucose was incorporated into ceil fractions, and the cells metabolized [14C]glucose to 14CO2. Amytal, rotenone, cyanide, azide, 2,4-dinitrophenol, and dicyclohexylcarbodiimide strongly inhibited [14C]glucose uptake activity, suggesting the presence of an en...

Sensitivity 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...
