Abstract: Fermentation bacteria (FB), sulfatereducing bacteria (SRB) and anaerobic cellulosedegrading bacteria at different depths in four peat sediments were accounted and the existence of methaneproducing bacteria was investigated. The result showed that the numbers of fermentation bacteria were positively correlated with the content of organic matter, especially with those of humic acid. There is no obvious relationship between the numbers of sulfatereducing bacteria and the contents of sulfate. However, to some extent the SRB are negatively correlated with the depths of samples. The minima of both sulfate contents and SRB numbers were found at the bottoms of four sediments. Anaerobic cellulosedegrading bacteria were only detected in several samples, while methaneproducing bacteria habited in all samples even in coexistence with sulfatereducing bacteria. The corresponding geological effects of these anaerobic bacteria on peat sediments were also analyzed in this paper.
