  • Title: [Thiosulfate oxidation by nonsulfur purple bacteria].
    Author: Keppen OI, Pedan LV, Rodova NA.
    Journal: Mikrobiologiia; 1980; 49(5):682-6. PubMed ID: 6777642.
    Abstract:
    The capability to oxidize thiosulfate was studied in 11 cultures of purple bacteria belonging to Rhodomicrobium vannielii, Rhodopseudmonas viridis, Rh. sphaeroides, Rh. capsulata, and Rhodospirillum rubrum. All the bacteria oxidized thiosulfate under aerobic conditions in the dark. The strains 2R, 8259, A1, A2 and D1 of Rh. sphaeroides oxidized thiosulfate under anaerobic conditions in the light, and the process was coupled with carbon dioxide fixation. All the strains contained thiosulfate reductase, and the majority of them possessed also the activity of thiosulfate oxidase and sulfite oxidase.
