Catabolite repression in the facultative chemoautotroph Thiobacillus novellus.
Several fermentable carbon sources were found to give rise to catabolite repression of all enzymes implicated in thiosulfate oxidation in the facultative chemoautotroph, Thiobacillus novellus. Glucose was found to elicit a strong repression. Glycerol, lactate, lactose, ribose, and pyruvate caused marked repression. In all cases, the repression could be relieved only by returning the cells to a ...
متن کاملSulfite oxidase activity in Thiobacillus novellus.
Thiobacillus novellus shows a maximum induction of sulfite oxidase activity and a maximum growth rate as a result of supplementing the autotrophic growth medium with 4.0 microM ammonium molybdate. Cells grown in the presence of molybdate showed approximately 10-fold increases in the amount of enzyme-associated molybdenum and in the sulfite-to-cytochrome c and sulfite-to-ferricyanide reductase a...
متن کاملIsolation and characterization of a bacteriophage for Thiobacillus novellus.
A DNA-containing bacteriophage for Thiobacillus novellus has been isolated from sewage and purified by ammonium sulfate precipitation, differential centrifugation, and cesium chloride equilibrium centrifugation. The buoyant density of this phage in CsCl is 1.51 g/cm(3). Electron microscopy studies have revealed a polyhedral head about 60 nm in diameter and a tail surrounded by a number of fine ...
متن کاملThiobacillus 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...
متن کاملOxalate, formate, formamide, and methanol metabolism in Thiobacillus novellus.
Thiobacillus novellus was able to grow with oxalate, formate, formamide, and methanol as sole sources of carbon and energy. Extensive growth on methanol required yeast extract or vitamins. Glyoxylate carboligase was detected in extracts of oxalate-grown cells. Ribulose bisphosphate carboxylase was found in extracts of cells grown on formate, formamide, and thiosulfate. These data indicate that ...
