Abstract

© 2017, Springer International Publishing Switzerland. A novel actinobacterial strain, designated FMN22T, was isolated from soil and characterised using a polyphasic approach. Strain FMN22T showed high 16S rRNA gene sequence similarity to Kribbella karoonensis Q41T (99.3%), Kribbella shirazensis UTMC 693T (99.0%), Kribbella aluminosa HKI 0478T (98.9%) and Kribbella hippodromi S1.4T (98.6%). Phylogenetic analysis using the 16S rRNA and concatenated gene (gyrB, rpoB, relA, recA and atpD) sequences showed that strain FMN22T is closely related to the type strains of K. karoonensis DSM 17344T, K. shirazensis UTMC 693T, K. aluminosa HKI 0478T, K. hippodromi S1.4T, Kribbella jejuensis HD9T and Kribbella solani DSA1T. Based on concatenated gene genetic distances analysis, strain FMN22T is distinct from all Kribbella type strains. DNA–DNA hybridization experiments with closely related type strains, were found to be 59.2 ± 2.4, 54.8 ± 2.1, 16.4 ± 2.3 and 38.6 ± 2.5%, relatedness to K. karoonensis DSM 17344T, K. shirazensis DSM 45490T, K. aluminosa DSM 18824T and K. jejuensis DSM 17305T, respectively. The cell wall peptidoglycan contained ll-diaminopimelic acid, and whole cell sugars were glucose, mannose and ribose. The predominant menaquinone was MK-9(H4). The major phospholipids are diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and phosphatidylinositol. Major fatty acids are anteiso-C15:0 and iso-C16:0. These chemotaxonomic traits are in good agreement with those known for representatives of the genus Kribbella. A combination of DNA–DNA hybridization results and phenotypic properties demonstrated that strain FMN22T can be clearly distinguished from all close phylogenetic relatives. Therefore, strain FMN22T (=DSM 27132T = KCTC 29219T) is considered to be the type strain of a novel species of the genus Kribbella, for which the name Kribbella soli is proposed.
