摘要: An actinomycete strain M4147(T) was isolated from sediment from Megas Gialos, Syros, Greece. The results of phylogenetic analysis of the 16S rRNA gene sequence of M4147(T) indicated that the highest similarity was with Actinoplanes atraurantiacus Y16(T) (98.9 %), Actinoplanes deccanensis IFO 13994(T) (98.8 %), Actinoplanes digitatis IFO 12512(T) (98.1 %) and Actinoplanes abujensis A4029(T) (98.0 %). The cell wall of the novel isolate contained meso-diaminopimelic acid and the whole-cell sugars were xylose, arabinose and glucose. The predominant menaquinones were MK-9(H-4), MK-9(H-6) and MK-9(H-2). The phospholipid profile comprised phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and an unknown phospholipid. The DNA G+C content was 71.5 mol%. Furthermore, a combination of DNA-DNA relatedness and some physiological and biochemical properties indicated that the novel strain could be readily distinguished from the most closely related species. On the basis of these phenotypic and genotypic data, M4I47(T) represents a novel species of the genus Actinoplanes, for which the name Actinoplanes sediminis sp. nov. is proposed. The type strain is M4I47(T) (=CCTCC AA 2016022(T) =DSM 100965(T)).
