    Abstract:
    A polyphasic approach was used to verify the novel actinomycete, strain 1SM4-01T, isolated from mangrove sediment collected from Ranong Province, Thailand. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the organism was a member of the genus Nonomuraea and was most closely related to Nonomuraea syzygii GKU 164T (98.7 % sequence similarity), Nonomuraea rhizophila YIM 67092T (98.4 %), Nonomuraea solani NEAU-Z6T (98.4 %), Nonomuraea monospora PT708T (98.3 %) and Nonomuraea thailandensis KC-061T (98.2 %). The strain produced branching aerial mycelium which differentiated into straight chains of rough-surfaced spores borne at the end of a short sporophore. The whole-cell hydrolysates contained meso-diaminopimelic acid as the diagnostic diamino acid, with madurose, mannose and ribose as the main sugars. MK-9(H4) was a major menaquinone of this strain. The acyl type of peptidoglycan was N-acetyl. The predominant cellular fatty acids were C17 : 1ω8c and iso-C16 : 0. Phospholipids consisted of diphosphatidylglycerol, hydroxy-phosphatidylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, aminophospholipids and unidentified lipids. The G+C content of the genomic DNA was 70.4 mol%. On the basis of phenotypic characteristics, DNA-DNA relatedness and phylogenetic distinctiveness, strain 1SM4-01T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea purpurea sp. nov. is proposed. The type strain is 1SM4-01T (=BCC 60397T=NBRC 109647T).
