Glucose-6-phosphate dehydrogenase from the chemolithotroph Thiobacillus ferrooxidans.
Glucose-6-phosphate dehydrogenase was partially purified from both glucose-grown and iron-glucose-grown Thiobacillus ferrooxidans. The enzyme possesses a dual nucleotide specificity for either nicotinamide adenine dinucleotide phosphate (NADP) or nicotinamide adenine dinucleotide (NAD) and has a molecular weight of 110,000 as determined by gel electrophoresis. Evidence is presented that T. ferr...
متن کاملSelective Adhesion of Thiobacillus ferrooxidans to Pyrite.
Bacterial adhesion to mineral surfaces plays an important role not only in bacterial survival in natural ecosystems, but also in mining industry applications. Selective adhesion was investigated with Thiobacillus ferrooxidans by using four minerals, pyrite, quartz, chalcopyrite, and galena. Escherichia coli was used as a control bacterium. Contact angles were used as indicators of hydrophobicit...
متن کاملMolecular genetics of Thiobacillus ferrooxidans.
Thiobacillus ferrooxidans is a gram-negative, highly acidophilic (pH 1.5 to 2.0), autotrophic bacterium that obtains its energy through the oxidation of ferrous iron or reduced inorganic sulfur compounds. It is usually dominant in the mixed bacterial populations that are used industrially for the extraction of metals such as copper and uranium from their ores. More recently, these bacterial con...
متن کاملAnaerobic Growth of Thiobacillus ferrooxidans.
The obligately autotrophic acidophile Thiobacillus ferrooxidans was grown on elemental sulfur in anaerobic batch cultures, using ferric iron as an electron acceptor. During anaerobic growth, ferric iron present in the growth media was quantitatively reduced to ferrous iron. The doubling time in anaerobic cultures was approximately 24 h. Anaerobic growth did not occur in the absence of elemental...
متن کاملPlasmid and transposon transfer to Thiobacillus ferrooxidans.
The broad-host-range IncP plasmids RP4, R68.45, RP1::Tn501, and pUB307 were transferred to acidophilic, obligately chemolithotrophic Thiobacillus ferrooxidans from Escherichia coli by conjugation. A genetic marker of kanamycin resistance was expressed in T. ferrooxidans. Plasmid RP4 was transferred back to E. coli from T. ferrooxidans. The broad-host-range IncQ vector pJRD215 was mobilized to T...
