Sulfur isotope fractionation during dissimilatory sulfate reduction by two strains of the thermophilic archaeon Archaeoglobus fulgidus (strains VC-16 and Z) was explored over the entire temperature range of growth. The optimal cell-specific sulfate reduction rate (14 fmol cell(-1) h(-1)) was found at 82-84 degrees C but growth was measured as low as 54 degrees C. The fractionation ranged between 0.52 per thousand and 27 per thousand, with largest fractionations were found at intermediate… CONTINUE READING
