摘要：

Stable sulfur isotope fractionation was investigated during reduction of thiosulfate by growing batch cultures of Dethiosulfovibrio russensis at a cell-specific reduction rate of 2.4±0.72 fmol cell–1 d–1 (28 °C). Citrate was used as carbon and energy source. The hydrogen sulfide produced by this sulfur- and thiosulfate-reducing bacterium was depleted in 34S by 11‰ compared to total thiosulfate sulfur, in agreement with previous results observed for sulfate-reducing bacteria. This indicates the operation of a similar pathway for thiosulfate reduction in these phylogenetically different bacteria.
