JF International Journal of Systematic and Evolutionary Microbiology, VO 65 IS Pt_9 SP 3143 OP 3147 DO https://doi.org/10.1099/ijsem.0.000393 PB Microbiology Society, SN 1466-5034, AB Strain XMU 706T, isolated from the rhizosphere soil of a herbaceous plant, Mirabilis jalapa L., collected from Xiamen City, China, was characterized using a polyphasic approach to clarify its taxonomic position. Strain XMU 706T shared the highest 16S rRNA gene sequence similarity with Kribbella antibiotica YIM 31530T (97.2 %), and formed a distinct branch in the subclade of the genus Kribbella in the 16S rRNA gene phylogenetic tree. The genetic distances of gyrase subunit B gene (gyrB) sequence between strain XMU 706T and other species of the genus Kribbella ranged from 0.045 to 0.116, greater than the threshold value of 0.014 for species delineation of this genus. DNA–DNA hybridization experiments gave a DNA–DNA relatedness value of 34.82 ± 6.31 % between strain XMU 706T and K. antibiotica YIM 31530T. The chemotaxonomic properties further supported the assignment of strain XMU 706T to the genus Kribbella. ll-Diaminopimelic acid was the diagnostic amino acid in the cell-wall peptidoglycan and cell hydrolysates contained ribose and glucose. The major menaquinone was MK-9(H4). The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and other unidentified phospholipids and lipids. The major fatty acids of the strain were anteiso-C15 : 0 and iso-C15 : 0, and the G+C content of the genomic DNA was 67.3 mol%. Based on the results of phylogenetic analysis, phenotypic and genotypic characterization, strain XMU 706T represents a novel species of the genus Kribbella, for which the name Kribbella mirabilis sp. nov. is proposed. The type strain is XMU 706T ( = KCTC 29676T = MCCC 1K00429T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000393
