abstract= A Gram-stain-positive, aerobic, motile and non-spore-forming actinobacterium, strain Y32T, was isolated from a deep-sea sediment of the western Pacific Ocean. Phylogenetic and phenotypic properties of the organism supported that it belonged to the genus Georgenia. Strain Y32T shared highest 16S rRNA gene sequence similarity of 97.8 % with Georgenia muralis 1A-CT, followed by Georgenia thermotolerans TT02-04T (97.4 %), Georgenia daeguensis 2C6-43T (97.2 %), Oceanitalea nanhaiensis JLT1488T (97.2 %), Georgenia ruanii YIM 004T (97.0 %) and Georgenia soli CC-NMPT-T3T (97.0 %). The organism grew in the presence of 0–10 % (w/v) NaCl, at 4–40 °C and at pH 6–11, with optimal growth occurring at 30–35 °C, at pH 7 and in the presence of 3.5 % (w/v) NaCl. The polar lipid profile of strain Y32T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two phosphatidylinositol mannosides. Strain Y32T contained MK-8(H4) and MK-7(H4) as the major components of the menaquinone system, and anteiso-C15 : 0, iso-C15 : 0 and iso-C14 : 0 as the predominant fatty acids. Galactose was detected as the cell-wall sugar. The G+C content of the DNA was 71.2 mol%. Based on the results of phenotypic, genotypic and phylogenetic analyses, it is considered that strain Y32T represents a novel species of the genus Georgenia, for which the name Georgenia subflava sp. nov. is proposed. The type strain is Y32T ( = LMG 28101T = CGMCC 1.12782T = JCM 19765T = MCCC 1A09955T).,
