Abstract
Marine strain D10-B, a Gram-negative, non-motile, facultative chemoautotrophic sulfur bacterium, oxidized thiosulfate to sulfate with the production of energy which was used for 14CO2 fixation. The assimilation of 14CO2 was almost completely inhibited by 5 × 10−4 M 2,4-dinitrophenol. Thiosulfate oxidation was inhibited by 47% in the presence of 5 × 10−4 M KCN. The thiosulfate-oxidizing system appeared to be inducible. Elemental sulfur, sulfite, and tetrathionate were also respired, but only thiosulfate served as a substrate for growth. Strain D10-B grew heterotrophically on a variety of single and complex organic substrates. The organism was compared to Thiobacillus novellus and Thiobacillus intermedins. It was classified as a marine strain of T. novellus.
