An actinomycete strain, designated YU1183-22T, was isolated from a compost sample collected in Nikko, Japan. The isolate formed white aerial mycelium with relatively long aerial hyphae showing chains of arthrospores. Strain YU1183-22T grew with 0–10 % (w/v) NaCl, at pH 6–11 and at 10–37 °C (optimum 30 °C). Strain YU1183-22T contained meso-diaminopimelic acid and no diagnostic sugars. The predominant menaquinones were MK-10(H10) and MK-10(H8). The polar lipids were phosphatidylcholine and phosphatidylglycerol. The major cellular fatty acids were iso-C16 : 0, anteiso-C17 : 0 and tuberculostearic acid. The G+C content of the DNA was 72.3 mol%. Chemotaxonomic and morphological characterization clearly demonstrated that strain YU1183-22T belonged to the genus Nocardiopsis. Phylogenetic analysis using 16S rRNA gene sequences showed that the isolate was closely related to Nocardiopsis salina YIM 90010T (98.0 % 16S rRNA gene sequence similarity), Nocardiopsis xinjiangensis YIM 90004T (97.9 %) and Nocardiopsis kunsanensis HA-9T (97.3 %). However, DNA–DNA relatedness as well as physiological and biochemical analyses showed that strain YU1183-22T could be differentiated from its closest phylogenetic relatives. It is proposed that this strain be classified as a representative of a novel species of the genus Nocardiopsis, with the name Nocardiopsis nikkonensis sp. nov. The type strain is YU1183-22T (=NBRC 102170T =KCTC 19666T).

A novel actinomycete strain, SMC 256T, which developed small, globose sporangia at the ends of long sporangiophores on aerial mycelium, was isolated from soil collected in a mountain forest of Thailand. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SMC 256T belonged to the genus Kutzneria, and the closest phylogenetically related species were Kutzneria buriramensis BCC 29373T (98.9 % 16S rRNA gene sequence similarity), Kutzneria kofuensis ATCC 27102T (98.2 %), Kutzneria albida ATCC 25243T (97.9 %) and Kutzneria viridogrisea ATCC 25242T (97.4 %). The DNA–DNA relatedness values that distinguished strain SMC 256T from previously described members of the genus Kutzneria were significantly below 70 %. The G+C content of the genomic DNA was 71.8 mol%. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The whole-cell sugars consisted of rhamnose, ribose, mannose, glucose and galactose. The predominant menaquinone was MK-9(H4). Mycolic acids were not detected. The diagnostic phospholipids were hydroxyphosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, unidentified phosphoglycolipids, unidentified phospholipids and an unidentified lipid. The predominant cellular fatty acids were iso-C16 : 0, C17 : 1 and C17 : 0 10-methyl. Following the evidence of phenotypic, chemotaxonomic and genotypic studies, it is proposed that strain SMC 256T represents a novel species in the genus Kutzneria, namely Kutzneria chonburiensis sp. nov. The type strain is SMC 256T ( = BCC 72675T = NBRC 110610T).

Strain XMU 506T, isolated from the rhizosphere soil of an ornamental plant, Lantana camara L., collected from Xiamen City, China, was identified using a polyphasic approach to clarify its taxonomic position. The aerial mycelium of this organism formed long straight or curved chains of spores and sporangium-like structures. The optimum growth occurred at 28–30 °C, pH 7.0 with 0–1 % NaCl. Strain XMU 506T showed the highest 16S rRNA gene sequence similarity (96.5  %) to Kibdelosporangium philippinense DSM 44226T, and formed a monophyletic clade in the 16S rRNA gene phylogenetic tree together with the type strains of the genus Kibdelosporangium. The chemotaxonomic properties further supported the assignment of strain XMU 506T to the genus Kibdelosporangium: meso-diaminopimelic acid was the diagnostic amino acid in the cell wall peptidoglycan; mycolic acids were not present in the cell wall; the whole-cell hydrolysates contained arabinose, galactose, glucose and ribose. The major menaquinone was MK-9(H4); the phospholipids of the isolate comprised phosphatidylethanolamine, OH-phosphatidylethanolamine, diphosphatidylglycerol and unidentified amino-, glyco- and phospholipids; the major fatty acids of the strain were iso-C16 : 0, C17 : 1 ω6c and iso-C16 : 1 H. The G+C content of genomic DNA was 67.3 mol%. Based on the results of phylogenetic analysis, phenotypic and genotypic characterization, strain XMU 506T represents a novel species in the genus Kibdelosporangium, for which the name Kibdelosporangium lantanae sp. nov. is proposed. The type strain is XMU 506T ( = KCTC 29675T = MCCC 1K00430T).
