Research Abstract |
The vertical distribution of sulfate-reducing bacteria was investigated in a shallow meromictic lake in cryosphere, Lake Harutori, Kushiro, Japan. Lake water was physicochemically characterized and a steep chemocline was observed. Identification and quantification of sulfate-reducing bacteria showed that Desulfosarcina-Desulfococcus group is one of the major groups of sulfate-reducing bacteria in the anoxic and sulfidic layer of Lake Harutori, and they might play an important role in sulfur cycling in the lake.
