Abstract
An endophytic actinobacterial strain, CS1-12T , was isolated from a leaf of Costus speciosus. Single spores were observed directly on the substrate mycelia. The cell-wall peptidoglycan of this strain exhibited meso-diaminopimelic acid and 3-OH-meso-diaminopimelic acid. Arabinose, glucose, ribose, xylose and rhamnose were detected as whole-cell sugars. The diagnostic phospholipids of this strain were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The predominant menaquinones were MK-10(H 6), MK-10(H 8), MK-9(H4) and MK-10(H 4). The main components of the cellular fatty acids (.10 %) were iso-C 15 : 0, anteiso-C 17 : 0, iso-C 16 : 0 and anteiso-C 15 : 0 . The G+C content of the genomic DNA was 72.8 mol%. 16S rRNA gene sequence analysis data showed that strain CS1-12 T should be classified in the genus Micromonospora and that it is closely related to Micromonospora fulviviridis DSM 43906T (99.3 %). The physiological, biochemical and chemotaxonomic properties, including the DNA–DNA hybridization results, indicated that strain CS1-12 T could be judged a novel species of the genus Micromonospora, for which the name Micromonospora costi sp. nov. is proposed. The type strain is CS1-12 T (5BCC 58124T5NBRC 109518T).
