removal of thiosulfate (s2o32-, 200 mg/l) from simulated wastewater samples was investigated under varying co-pollutants and ph conditions employing the titanium dioxide (tio2) mediated photocatalysis. for thiosulfate only studies higher substrate removal was noted at lower ph with a specific trend of ph 4 > ph 7 > ph 10. furthermore, near complete thiosulfate removal was also achieved at ph 4....

Secretion of thiosulfate is maximally inhibited by carinamide at plasma levels as low as 20 pg/ml; sulfa...

Thiosulfate respiration in Salmonella enterica serovar Typhimurium is catalyzed by the membrane-bound enzyme thiosulfate reductase. Experiments with quinone biosynthesis mutants show that menaquinol is the sole electron donor to thiosulfate reductase. However, the reduction of thiosulfate by menaquinol is highly endergonic under standard conditions (ΔE°' = -328 mV). Thiosulfate reductase activi...

Cell yields of Rhodopseudomonas palustris grown photoheterotrophically in pyruvate-mineral salts medium were increased by the photooxidation of added thiosulfate. However, thiosulfate had no effect on cell yields of cultures grown aerobically in darkness, although thiosulfate was also oxidized. The presence of thiosulfate increased photosynthetic cell yields on a variety of other organic substr...

The mixotrophic growth with methanol plus thiosulfate was examined in nutrient-limited mixotrophic condition for Methylobacterium goesingense CBMB5 and Methylobacterium fujisawaense CBMB37. Thiosulfate oxidation increased the growth and protein yield in mixotrophic medium that contained 150 mM methanol and 20 mM sodium thiosulfate, at 144 h. Respirometric study revealed that thiosulfate was the...

The fate of 35-S during anaerobic metabolism of [35-S]sulfate, [35-S]thiosulfate, and [35-S]sulfate plus unlabeled thiosulfate by washed cell suspensions of Desulfovibrio spp, and of [35-S]thiosulfate by growing D. desulfuricans was examined. The results appear to be inconsistent with the hypothesis that thiosulfate is an intermediate in sulfate reduction. Since thiosulfate was produced from tr...

BACKGROUND Sodium thiosulfate therapy has been proposed for calcific uremic arteriolopathy and nephrogenic systemic fibrosis in hemodialysis patients. The treatment brings 3.7 g (161 mmol) of sodium. How to counterbalance this sodium load was studied. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Plasma conductivity (Cp) and mass balance index were compared for 20 sessions without thiosulfate...

The leaching behaviors of gold and silver from a complex sulfide concentrate in copper-tartrate-thiosulfate solutions were investigated this paper. Experimental parameters, including temperature, initial pulp pH, concentration copper, tartrate, thiosulfate, systematically studied. system exhibits promising performance dealing with the concentrate. Thiosulfate consumption could be greatly reduce...

Abstract Ethylenediaminetetraacetic acid disodium (EDTA) can form stable complexes with many metals. To improve the leaching rate of gold and consumption thiosulfate, EDTA ammonia were combined copper ions to a copper-EDTA-ammonia-thiosulfate system. Electrochemical methods used study effect ion, EDTA, polarization voltage. The results showed that increasing concentrations ions, promoted dissol...

Thiosulfate-oxidizing enzyme has been demonstrated in cell-free extracts of the marine, thiosulfate-oxidizing pseudomonad strain 16B. The enzyme, partially purified by ion-exchange chromatography and calcium phosphate gel treatment, catalyzed the oxidation of thiosulfate to tetrathionate with the concomitant reduction of ferricyanide. Native but not mammalian cytochrome c was also reduced by th...
