一种好氧、少营养、革兰氏阳性、无孢子化、能动、杆状、浸出钯的细菌菌株，德诺球菌。KR-1以前是从日本收集的池塘水中分离出来的。该菌株在10℃~40℃(最适30℃)、pH 4.5~11.5(最适pH 8.0)和2.0%的氯化钠存在下生长。其主要细胞脂肪酸为C-15：1 omega 6和C-16：1 omega 7c。根据4个看家基因(atpD、Dna A、gyrB和rpoB)的部分序列进行的多位点序列分析表明，该菌具有分枝现象。KR-1与志贺氏菌属分离株距离较远。KR-1株与其亲缘关系最近的志贺氏菌株基因组平均核苷酸同源性小于95.69%。根据其表型、化学分类和系统发育数据，菌株KR-1(=HUT-8138(T)=KCTC 33977(T))可被认为是变形球菌属中的一个新种，建议命名为变形球菌。11月
An aerobic, oligotrophic, Gram-positive, non-sporulating, motile, rod-shaped, palladium-leaching bacterial strain, Deinococcus sp. KR-1, was previously isolated from pond water collected in Japan. This strain grew at 10 degrees C to 40 degrees C (optimum 30 degrees C), at pH 4.5 to 11.5 (optimum pH 8.0), and in the presence of 2.0% NaCl. Its major cellular fatty acids were C-15: 1 omega 6 and C-16 : 1 omega 7c. The quinone system was menaquinone 8. Multilocus sequence analysis based on partial sequences of four housekeeping genes (atpD, dnaA, gyrB and rpoB) showed that branching of Deinococcus sp. KR-1 was distant to those of Deinococcus type strains. The genome average nucleotide identity value between strain KR-1 and its closest related Deinococcus type strain was less than 95.69%. Based on its phenotypic, chemotaxonomic and phylogenetic data, strain KR-1 (= HUT-8138(T) = KCTC 33977(T)) can be considered a novel species within the genus Deinococcus with the proposed name Deinococcus kurensis sp. nov.
