Distribution of sulfate-reducing bacteria (SRB) utilizing lactate (1-SRB), propionate (p-SRB) and acetate (a-SRB) was examined along with some physico-chemical environmental factors in various aquatic environments with various trophic levels and various salinities. In marine environments a-SRB showed a tendency to dominate SRB, except for several samples. On the other hand, in freshwater environments 1-SRB tended to dominate SRB. However, a-SRB were found abundantly as well as 1-SRB in hypertrophic freshwater sediments. The relationship between distribution of 1-, p- or a-SRB and environmental factors was discussed.
