Impact of bacterial NO3(super -) transport on sediment biogeochemistry
Article Abstract:
A study is conducted to demonstrate that Beggiatoa could induce a H2S-depleted suboxic zone of more than 10 mm in marine sediments and cause a divergence in sediment NO3(super -) reduction from denitrification to dissimilatory NO3(super -) reduction to ammonium. pH, O2, and H2S profiles indicated that the bacteria oxidized H2S with NO3(super -) and transported S(super 0) to the sediment surface for aerobic oxidation.
