Abstract
Ferrous sulfate was added to batch cultures of Sulfobacillus (Sb.) acidophilus, Sb. thermosulfidooxidans and Sb. sibiricus at the start of the exponential growth phase during growth on tetrathionate. Soluble ferrous ion and polythionate concentrations were used as a measure of substrate utilisation. Sb. thermosulfidooxidans switched from utilising polythionates to exclusively oxidising ferrous ions, only then oxidising the remainder of the polythionates. Sb. sibiricus and Sb. acidophilus did not cease polythionate oxidation but utilised both substrates concurrently after ferrous ion addition. None of the cultures tested exhibited preferential polythionate utilisation, even though they were utilising polythionate prior to the addition of ferrous ions.
