Actinoplanes sediminis sp. nov., isolated from marine sediment
2018
An actinomycete strain M4I47T was isolated from sediment from Megas Gialos, Syros, Greece. The results of phylogenetic analysis of the 16S rRNA gene sequence of M4I47T indicated that the highest similarity was with
Actinoplanes atraurantiacus
Y16T (98.9 %),
Actinoplanes deccanensis
IFO 13994T (98.8 %),
Actinoplanes digitatis
IFO 12512T (98.1 %) and
Actinoplanes abujensis
A4029T (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(H4), MK-9(H6) and MK-9(H2). 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, M4I47T represents a novel species of the genus
Actinoplanes
, for which the name
Actinoplanes
sediminis sp. nov. is proposed. The type strain is M4I47T (=CCTCC AA 2016022T=DSM 100965T).
