sp. nov., isolated from the rhizosphere soil of an ornamental plant, L. Free

Abstract

Strain XMU 506, isolated from the rhizosphere soil of an ornamental plant, 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 506 showed the highest 16S rRNA gene sequence similarity (96.5  %) to DSM 44226, and formed a monophyletic clade in the 16S rRNA gene phylogenetic tree together with the type strains of the genus . The chemotaxonomic properties further supported the assignment of strain XMU 506 to the genus : -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(H); 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-C, C ω6 and iso-C 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 506 represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is XMU 506 ( = KCTC 29675 = MCCC 1K00430).
