Abstract

Strain DJ57 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 with 95.83 % nucleotide identity to THYL-44, while the similarities to other type strains of species of the genus were less than 95.76 %. The major isoprenoid quinone was menaquinone-7 and the major fatty acids (>5 %) were iso-C, iso-C 3-OH, iso-C G, anteiso-C and iso-C. 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 DJ57 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DJ57 ( = KCTC 42474 = CCTCC AB 2015052).
