Polyphasic analysis of ten isolates of the red-pigmented bacteria isolated from ten Arthrospira cultures originating from different parts of the world is described. The 16S rRNA analysis showed <95 % identity with the known bacteria on public databases, therefore, additional analyses of fatty acids profiles, MALDI-TOF/MS, genome sequencing of the chosen isolate and following phylogenomic analyses were performed. Gram-stain-negative, strictly aerobic rods were positive for catalase, negative for oxidase, proteolytic and urease activity. Major fatty acids were 15 : 0 iso, 17:0 iso 3 OH and 17:1 iso w9c/16:0 10-methyl. The whole phylogenomic analyses revealed that the genomic sequence of newly isolated strain DPMB0001 was most closely related to members of Cyclobacteriaceae family and clearly indicated distinctiveness of newly isolated bacteria. The average nucleotide identity and in silico DNA–DNA hybridisation values were calculated between representative of the novel strains DPMB0001 and its phylogenetically closest species, Indibacter alkaliphilus CCUG57479 (LW1)^T (ANI 69.2 % is DDH 17.2 %) and Mariniradius saccharolyticus AK6^T (ANI 80.02 % isDDH 26.1 %), and were significantly below the established cut-off <94 % (ANI) and <70 % (isDDH) for species and genus delineation.

The obtained results showed that the analysed isolates represent novel genus and species, for which names Arthrospiribacter gen nov. and Arthrospiribacter ruber sp. nov. (type strain DPMB0001 = LMG 31078 = PCM 3008) is proposed.

描述了从世界不同地区的十种节肢动物培养物中分离出的十种红色色素细菌分离物的多相分析。16S rRNA分析显示，与公共数据库中已知细菌的同一性<95％，因此，对脂肪酸谱，MALDI-TOF / MS，所选分离物的基因组测序进行了进一步分析，并进行了系统发育分析。革兰氏染色阴性，严格好氧的杆的过氧化氢酶呈阳性，氧化酶，蛋白水解和脲酶活性呈阴性。主要脂肪酸为15：0异，17：0异3 OH和17：1异w9c / 16：0 10-甲基。整个系统生物学分析表明，新分离出的菌株DPMB0001的基因组序列与环菌科成员最密切相关。家族并清楚地表明了新分离细菌的独特性。计算了代表新菌株DPMB0001及其系统发育最接近物种嗜碱靛蓝CCUG57479（LW1）^T（ANI 69.2％为DDH 17.2％）和Mariniradius saccharolyticus AK6 ^T（ANI ）之间的平均核苷酸同一性和计算机内DNA-DNA杂交值。80.02％是DDH 26.1％），并且显着低于既定的阈值<94％（ANI）和<70％（是DDH），以区分物种和属。

获得的结果表明，所分析的分离物代表了新的属和种，并命名为Arthrospiribacter gen nov。和节杆菌属菌擦。十一月 （型号为DPMB0001 = LMG 31078 = PCM 3008）。
