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...
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 کاملKinetics 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...
متن کاملRelation 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...
متن کاملOxidation of Ferrous Iron and Elemental Sulfur by Thiobacillus ferrooxidans.
The oxidation of ferrous iron and elemental sulfur by Thiobacillus ferrooxidans that was absorbed and unabsorbed onto the surface of sulfur prills was studied. Unadsorbed sulfur-grown cells oxidized ferrous iron at a rate that was 3 to 7 times slower than that of ferrous iron-grown cells, but sulfur-grown cells were able to reach the oxidation rate of the ferrous iron-adapted cells after only 1...
