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 کاملThiosulphate Oxidation in Thiobacillus
bacterium Thiobacillus X. A fifth fraction (acidic fraction) contained two additional cytochrome components with x bands at 550 and 557 msi respectively in the reduced state. 2. All the cytochromes appear to be ofthe c type, are labile to heat and acid and do not combine with carbon monoxide. They are auto-oxidizable to varying degrees. 3. Cytochromes 550 (1) and 557 (1) are basic, and are adso...
متن کاملThiosulphate Oxidation by Thiobacillus Strain C
1. Thiobacillus strain C oxidized [35S]thiosulphate completely to sulphate. 2. During thiosulphate oxidation [35S]sulphate was formed more rapidly from (S. 35SO3)2than from (35S *SO3)2-. 35S disappeared less rapidly from thiosulphate with (35S SO3)2as substrate than with (S.35SO3)2-. 3. Thiosulphate labelled in both atoms was produced during (35S * SO3)2oxidation, but not during (S. 35SO3)2oxid...
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...
