Glycomyces phytohabitans sp. nov., a novel endophytic actinomycete isolated from the coastal halophyte in Jiangsu, East China.

ABSTRACT

A novel endophytic actinomycete, designated strain KLBMP 1483(T), was isolated from the stem of the coastal plant Dendranthema indicum (Linn.) Des Moul collected from Nantong, in East China. Phylogenetic analysis showed that strain KLBMP 1483(T) was affiliated with the genus Glycomyces within the family Glycomycetaceae and shared the highest 16S rRNA gene sequence similarities with the type strains of Glycomyces arizonensis NRRL B-16153(T) (96.7%) and Glycomyces tenuis IFO 15904(T) (96.2%), and lower similarities (94.1-95.1%) to the other members of the genus Glycomyces, which distinguished KLBMP 1483(T) from representatives of the genus Glycomyces. The whole-cell hydrolysates contained meso-diaminopimelic acid, glucose, xylose and galactose. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, two unknown aminophospholipids, two phosphoglycolipids, two unknown phospholipids and one unknown lipid. MK-10(H4) was the predominant menaquinone. The major fatty acids were iso-C150, anteiso-C150, iso-C160, iso-C161 G and anteiso-C170. On the basis of the phenotypic and genotypic characteristics presented in this study, strain KLBMP 1483(T) represents a novel species, for which the name Glycomyces phytohabitans sp. nov. is proposed. The type strain is KLBMP 1483(T) (NBRC 109116(T)=DSM 45766(T)).
