The effects of thiosulphate and oxygen concentration on tetrathionate oxidation by Thiobacillus X and T. thioparus.
in the 2-week-old rats, ascorbic acid either performs additional functions or performs the same functions as in the other two groups but at accelerated rates. Since the bone marrow is predominantly engaged in the production of blood cells, it is possible that some relationship may exist between the rate of production of blood cells and the quantity of ascorbic acid available to the bone marrow....
متن کاملSome properties of the rhodanese system of Thiobacillus denitrificans.
1. Rhodanese has been extracted from Thiobacillus denitrificans by ultrasonic disintegration of the cells. 2. Studies with Sephadex columns have shown that the enzyme aggregates, forming a tetramer. 3. The molecular weights of the monomer and of an enzymically active sub-unit one-quarter this size have been determined by gel filtration. 4. Higher-molecular-weight forms of rhodanese are broken d...
متن کاملThe occurrence of polythionates as intermediates in the metabolism of thiosulphate by the thiobacilli.
Further evidence for the inclusion of polythionates in the pathway of thiosulphate oxidation by members of the genus Thiobacillus is presented. Manometric experiments showed tetrathionate oxidation to be a stage in thiosulphate oxidation by suspensions of T. thioparus and T. thiocyanoxidans. Thiobltcillus thioparus accumulated a sufficient concentration of polythionate in the medium to allow ch...
متن کاملAssimilation and metabolism of exogenous organic compounds by the strict autotrophs Thiobacillus thioparus and Thiobacillus neapolitanus.
The assimilation and utilization of the individual carbon atoms of pyruvate and acetate by cells of Thiobacillus thioparus and T. neapolitanus, in the presence and absence of an energy source, were studied by use of radioactive substrates. Both organisms produced (14)CO(2) from (14)C-labeled pyruvate, but more came from carbon 1 than from carbons 2 or 3. The conversion of the carbons of acetate...
متن کاملConfirmation of Thiobacillus denitrificans as a species of the genus Thiobacillus, in the beta-subclass of the Proteobacteria, with strain NCIMB 9548 as the type strain.
Thiobacillus denitrificans is physiologically similar to the type species of the genus Thiobacillus, Thiobacillus Thioparus, and both are located in the beta-subclass of the Proteobacteria. T. denitrificans is distinguished from all other Thiobacillus species by its ability to grow as a facultatively anaerobic chemolithotroph, coupling the oxidation of inorganic sulfur compounds to the reductio...
