abstract= A novel endophytic actinobacterium, designated strain IP6SC6T, was isolated from surface-sterilized bark of Bruguiera gymnorhiza collected from Zhanjiang Mangrove Forest National Nature Reserve in Guangdong, China. Cells of strain IP6SC6T were Gram-stain-positive, aerobic, non-spore-forming, non-motile rods. Strain IP6SC6T grew at 20–42 °C (optimum, 37 °C), at pH 6.0–9.0 (optimum, pH 7.0) and in the presence of 0–8 % (w/v) NaCl (optimum, 0–2 %). Chemotaxonomic analyses showed that the isolate possessed meso-diaminopimelic acid as the diamino acid of the peptidoglycan, galactose and glucose as whole-cell sugars, and MK-8(H4) as the predominant menaquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylinositol and an unknown lipid. The major fatty acids were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C16 : 0. The G+C content of the genomic DNA was 72.5 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain IP6SC6T belonged to the genus Phycicoccus and shared the highest sequence similarity with Phycicoccus jejuensis NRRL B-24460T (96.97 %). On the basis of phylogenetic analysis and phenotypic and chemotaxonomic characteristics, strain IP6SC6T represents a novel species of the genus Phycicoccus, for which the name Phycicoccus endophyticus sp. nov. is proposed. The type strain is IP6SC6T ( = DSM 100020T = CGMCC 4.7300T).,
