Microbial sulfur cycle in aquatic systems of cryosphere is still unclear although the significance of systems linking carbon and nitrogen cycles has been pointed out. Analysis of aprA gene, which encodes a key enzyme in dissimilatory sulfate reduction and sulfur oxidation, showed that newly isolated Sulfuricella denitrificans-like sulfur oxidizer is a key species from geographically distant lakes in Antarctica and Japan. The complete genome sequence analysis indicated their unique sulfur metabolic pathway adapting freshwater environment. The proteomics results suggest that maintenance of proper translation is critical for growth under low-temperature.

冰冻圈水生系统中的微生物硫循环尚不清楚，尽管已经指出了连接碳和氮循环的系统的重要性。aprA基因编码异化硫酸盐还原和硫氧化的关键酶，分析结果表明，新分离的类硫氧化硫菌是来自地理位置遥远的南极洲和日本湖泊的关键种。全基因组序列分析表明它们具有独特的适应淡水环境的硫代谢途径。蛋白质组学结果表明，维持适当的翻译对低温下的生长至关重要。
