Abstract:
A novel actinomycete, designated strain KLBMP 1279 T , was isolated from surface-sterilized roots of a coastal halophyte, Salicornia europaea Linn., collected from Jiangsu Province, in the east of China. The taxonomic status of this organism was established using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain KLBMP 1279 T was closely related to Modestobacter marinus 42H12-1 T (99.5 % 16S rRNA gene sequence similarity), Modestobacter versicolor CP153-2 T (98.4 %) and Modestobacter multiseptatus AA-826 T (97.5 %). Chemotaxonomic characteristics were consistent with its assignment to the genus Modestobacter in that the isolate had meso -diaminopimelic acid as the diagnostic diamino acid in the cell wall, MK-9(H 4 ) as major menaquinone and a polar lipid profile containing diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, two unknown aminophospholipids and an unknown phospholipid. The predominant fatty acids were iso-C 16 : 0 , iso-C 15 : 0 and C 17 : 1 ω8 c . The DNA G+C content was 71.7 mol%. However, DNA–DNA hybridization assays as well as physiological and biochemical analyses differentiated strain KLBMP 1279 T from its closest phylogenetic relatives. On the basis of phenotypic, chemotaxonomic and phylogenetic evidence, the isolate KLBMP 1279 T represents a novel species of the genus Modestobacter , for which the name Modestobacter roseus sp. nov. is proposed; the type strain is KLBMP 1279 T ( = KCTC 19887 T = NBRC 108673 T = DSM 45764 T ). An emended description of the genus Modestobacter is also proposed.
