The fractionation of sulfur isotopes by the thermophilic chemolithoautotrophic Thermodesulfatator indicus was explored during sulfate reduction under excess and reduced hydrogen supply, and the full temperature range of ...

In bacterial cultures we measured sulfur isotope fractionation during transformations of thiosulfate (S2O32-) and sulfite (SO32-), pathways which may be of considerable importance in the cycling of sulfur in marine sediments ...

A synthesis of previous results, which we dub the "standard model," provides a prediction as to how isotope fractionation during sulfate reduction should respond to physiological variables such as specific rate of sulfate ...
