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.

本文对日本钏路春鸟湖冰冻圈浅裂性湖泊中硫酸盐还原菌的垂直分布进行了研究。湖水的物理化学特征和陡峭的化学跃层观察。硫酸盐还原菌的鉴定和定量分析表明，脱硫肉瘤-脱硫球菌是春取湖缺氧层和硫化物层中硫酸盐还原菌的主要类群之一，它们可能在春取湖硫循环中发挥重要作用。
