Formatted Abstract/Summary
Microbial sulfate reduction is the dominant process in the anaerobic mineralization of organic matter in continental margin sediments (Jørgensen, 1982). While sulfate-reducing bacteria (SRB) are generally accepted to occur in environments of pH 6 – 8 (Widdel, 1988), recent studies have demonstrated sulfate reduction in low pH habitats like acidic lakes and rivers, areas of acid mine drainage, and CO2-discharging hydrothermal vents. The latter are of particular interest, representing a system in which the degassing-effects of previously sequestered CO2 can be investigated.

Incubation experiments were conducted on sediments from the low pH shallow-sea hydrothermal vent system of Palaeochori Bay, Milos Island, Greece...
