Terriglobus saanensis SP1PR4(T) is a novel species of the genus Terriglobus. T. saanensis is of ecological interest because it is a representative of the phylum Acidobacteria, which are dominant members of bacterial soil microbiota in Arctic ecosystems. T. saanensis is a cold-adapted acidophile and a versatile heterotroph utilizing a suite of simple sugars and complex polysaccharides. The genome contained an abundance of genes assigned to metabolism and transport of carbohydrates including gene modules encoding for carbohydrate-active enzyme (CAZyme) family involved in breakdown, utilization and biosynthesis of diverse structural and storage polysaccharides. T. saanensis SP1PR4(T) represents the first member of genus Terriglobus with a completed genome sequence, consisting of a single replicon of 5,095,226 base pairs (bp), 54 RNA genes and 4,279 protein-coding genes. We infer that the physiology and metabolic potential of T. saanensis is adapted to allow for resilience to the nutrient-deficient conditions and fluctuating temperatures of Arctic tundra soils.
萨阿内斯土栖球囊菌SP1PR4(T)是土栖球囊菌属的一个新物种。萨阿内斯土栖球囊菌具有生态学意义，因为它是酸杆菌门的代表，而酸杆菌门是北极生态系统中细菌土壤微生物群的主要成员。萨阿内斯土栖球囊菌是一种适应寒冷的嗜酸菌，也是一种多功能异养生物，能利用一系列单糖和复合多糖。该基因组包含大量与碳水化合物代谢和转运相关的基因，包括编码参与多种结构和储存多糖分解、利用和生物合成的碳水化合物活性酶（CAZyme）家族的基因模块。萨阿内斯土栖球囊菌SP1PR4(T)是土栖球囊菌属中第一个具有完整基因组序列的成员，其基因组由一个5,095,226碱基对（bp）的单一复制子组成，包含54个RNA基因和4,279个蛋白质编码基因。我们推断，萨阿内斯土栖球囊菌的生理特性和代谢潜力使其能够适应北极苔原土壤养分缺乏和温度波动的条件。
