Three psychrotrophic Arthrobacter strains, isolated from Antarctic lake sediment (An24, An25T) and deep-sea sediment (ZX6) were studied. Their 16S rRNA gene sequences showed highest similarities (97.0-97.9%) with those of A. nicotianae and A. protophormiae. All three strains underwent rod-coccus morphological change, had high mol% G+C content, were aerobic to slightly anaerobic, and grew between 0 degrees C and 30 degrees C, with optimal growth temperature around 25 degrees C. The cell wall peptidoglycan was A4alpha variant. DNA-DNA hybridization, physiological and chemotaxonomic studies indicated that these three strains constituted a new homogeneous genomic species within the genus Arthrobacter, for which the name Arthrobacter ardleyensis, with the type strain An25T (CGMCC 1.3685, JCM 12921) was proposed.
对从南极湖泊沉积物（An24、An25T）和深海沉积物（ZX6）中分离出的三株嗜冷节杆菌菌株进行了研究。它们的16S rRNA基因序列与烟草节杆菌和原光节杆菌的序列显示出最高的相似性（97.0 - 97.9%）。所有三株菌株都经历了杆状 - 球菌形态变化，具有高摩尔百分比的G + C含量，好氧至微厌氧，在0℃至30℃之间生长，最佳生长温度约为25℃。细胞壁肽聚糖为A4α变体。DNA - DNA杂交、生理和化学分类学研究表明，这三株菌株构成了节杆菌属内一个新的同基因组物种，为此提出了名为阿德利节杆菌（Arthrobacter ardleyensis）的名称，模式菌株为An25T（CGMCC 1.3685，JCM 12921）。
