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 growth (40–80 C). Fractionation of sulfur isotopes measured under reduced H2 conditions in a fed-batch culture revealed high fractionations (24–37&) compared to fractionations produced under excess H2 supply (1–6&). Higher fractionations correlated with lower sulfate reduction… CONTINUE READING
