The pio Operon Is Essential for Phototrophic Fe(II) Oxidation in Rhodopseudomonas palustris TIE-1 [PDF]
Phototrophic Fe(II)-oxidizing bacteria couple the oxidation of ferrous iron [Fe(II)] to reductive CO2 fixation by using light energy, but until recently, little has been understood about the molecular basis for this process. Here we report the discovery,

Phospholipids of Thiobacillus thiooxidans [PDF]
Cells and spent growth media from sulfur- and thiosulfate-grown cultures of Thiobacillus thiooxidans were analyzed. The phosphatides were examined by thinlayer chromatography, and the products of their hydrolysis by hydrochloric acid and methanolic potassium hydroxide were separated by paper chromatography.

Insights Into the Carboxyltransferase Reaction of Pyruvate Carboxylase From the Structures of Bound Product and Intermediate Analogs [PDF]
Pyruvate carboxylase (PC) is a biotin-dependent enzyme that catalyzes the MgATP- and bicarbonate-dependent carboxylation of pyruvate to oxaloacetate, an important anaplerotic reaction in central metabolism.

Application of Acidithiobacillus ferrooxidans for recovering metals from electronic waste dust [PDF]
The paper discusses metal recovery from metallic wastes by means of pure chemical and biological leaching in an acidic medium. The research tested whether it is possible to remove Cu, Al, Sn and Ag from the dust formed during processing of electronic ...

Ultrastructure of a Marine Thiobacillus [PDF]
SUMMARY: The ultrastructure of Thiobacillus sp. IV-85 was examined by thin section and freeze-etch techniques. The morphology of this marine isolate was similar to that of terrestrial species of Thiobacillus. Decline phase preparations showed a marked degeneration of internal organization.

Uso combinado de dos biorreactores en la biolixiviación de un mineral sulfurado de cobre
La biolixiviación de minerales sulfurados de baja ley, utilizando microorganismos mesófilos, es una vía alternativa económicamente viable para la recuperación de ciertos metales de bajo costo. Habitualmente, los procesos de biolixiviación se realizan con
