1. A influência do Thiobacillus Thiooxidans na corrosão do aço inoxidável 430 em H2SO4 1 mol L-1
A corrosão microbiológica é um dos grandes problemas industriais da atualidade. O objetivo desse trabalho é estudar a influência da Thiobacillus Thiooxidans (TT) na corrosão do aço inoxidável 430 em H2SO4 1mol L-1. Nesse trabalho, foram empregadas as técnicas de: medidas gravimétricas, polarização anódica potenciostática (PA) e potenciodinâmic

2. EFEITO DO THIOBACILLUS THIOOXIDANS NA CORROSÃO DO AÇO 430
É de conhecimento que metais imersos em sistemas aquosos são facilmente colonizados por microorganismos. Como conseqüência desta colonização, a superfície metálica se torna coberta por um biofilme. Estes Biofilmes microbianos são muito complexos devido as suas diferentes populações microbianas. Normalmente são em forma poliméricas separados por

3. Reduction of chromium (VI) by the indirect action of Thiobacillus thioparus
The microbial reduction of chromium(VI) to chromium(III) has been one of the most widely studied forms of metal bioremediation. Recently, we have found that Thiobacillus ferrooxidans and Thiobacillus thiooxidans, growing on elemental sulphur, can indirectly promote chromium(VI) reduction by producing reducing agents such as sulphite and thiosulphate, which a

6. ATTACHMENT OF THIOBACILLUS THIOOXIDANS TO SULFUR CRYSTALS
Schaeffer, W. I. (Rutgers, The State University, New Brunswick, N.J.), P. E. Holbert, and W. W. Umbreit. Attachment of Thiobacillus thiooxidans to sulfur crystals. J. Bacteriol. 85:137–140. 1963.—Electron micrographs of replicas of sulfur crystals before and after attack by Thiobacillus thiooxidans show that the microorganisms erode the crystal in the ar

7. Isolation of an Ornithine-containing Lipid from Thiobacillus thiooxidans
The ornithine-containing lipid was separated from the other lipids of Thiobacillus thiooxidans by thin-layer chromatography. The aminolipid possesses both amide and ester linkages.

8. GROWTH OF THIOBACILLUS THIOOXIDANS IN SHAKEN CULTURE1
Cook, Thomas M. (Rutgers, The State University, New Brunswick, N.J.). Growth of Thiobacillus thiooxidans in shaken culture. J. Bacteriol. 88:620–623. 1964.—When flasks of sulfur-containing medium were inoculated with Thiobacillus thiooxidans and placed on a shaking machine immediately after inoculation, growth was markedly inhibited. If various wetting a

9. Localization of quantitation of the ornithine lipid of Thiobacillus thiooxidans.
The ornithine lipid of Thiobacillus thiooxidans was found to be 1.9% of the total polar lipids. Approximately 80% of this lipid was found to be localized in the outer membrane.

10. Transfer of IncP Plasmids to Extremely Acidophilic Thiobacillus thiooxidans
The broad-host-range IncP plasmids RP4, R68.45, RP1::Tn501, and and pUB307 were transferred directly to extremely acidophilic Thiobacillus thiooxidans from Escherichia coli by conjugation at frequencies of 10-5 to 10-7 per recipient. The ability of T. thiooxidans to receive and express the antibiotic resistance markers was examined. The plasmid RP4 was trans

11. Oxidation of Elemental Sulfur to Sulfite by Thiobacillus thiooxidans Cells
Thiobacillus thiooxidans cells oxidized elemental sulfur to sulfite, with 1 mol of O2 consumption per mol of sulfur oxidized to sulfite, when the oxidation of sulfite was inhibited with 2-n-heptyl-4-hydroxyquinoline N-oxide.
