Strain DJ57T is a Gram-reaction-negative, filamentous-shaped, non-flagellated, aerobic bacterium isolated from farmland soil in Hunan province of China. 16S rRNA gene sequence analysis demonstrated that this isolate belonged to the genus Niastella, with 95.83% nucleotide identity to Niastella populi THYL-44T, while the similarities to other type strains of species of the genus Niastella were less than 95.76%. The major isoprenoid quinone was menaquinone-7 and the major fatty acids (>5%) were iso-C15:0, iso-C17:0 3-OH, iso-C15:1 G, anteiso-C15:0 and iso-C16:0. The DNA G+C content was 44 mol%. Polar lipids were phosphatidylethanolamine, three unknown aminophospholipids, three unknown phospholipids and six unknown lipids. The chemotaxonomic, phenotypic and genotypic data indicated that strain DJ57T represents a novel species of the genus Niastella, for which the name Niastella vici sp. nov. is proposed. The type strain is DJ57T (=KCTC 42474T=CCTCC AB 2015052T).
