Sulfate reduction activity in SL sediment slurries inoculated with ML sediment. Sulfate reduction was stimulated at 25 and 90 g liter−1 salinity in SL sediments that received 3% (by volume) active ML sediment as an inoculum (open symbols). No activity was observed in SL slurries where sterilized ML sediment was used as the inoculum (closed symbols). Incubation time was 10 days.
