Relative abundance in the nonstimulated control and after 48 and 72 hours of stimulation with thiosulfate and different electron acceptors. Organisms were considered stimulated if their abundance increased at least by 30% compared to the nonstimulated control (indicated in boldface).
Potentially chemolithoautotrophic bacterium.
