A Gram-staining-positive, aerobic non-spore-forming and short-rod-shaped endophytic actinomycete was isolated from a branch of Sonneratia apetala, designated strain BGMRC0092(T) and investigated in detail data to determine its taxonomic position. On the basis of the 16S rRNA gene sequence analysis, the results of the phylogenetic analyses indicated that BGMRC0092(T) was most closely related to Nocardioides alpinus Cr7-14(T) (96.9 %), Nocardioides oleivorans DSM16090(T) (96.4 %) and Nocardiodes exalbidus RC825(T) (96.3 %). The predominant cellular fatty acids of BGMRC0092(T) were iso-C-16:0 and C-18:1 omega 8c. The major menaquinone was MK-8(H-4). The diagnostic diamino acid in the cell-wall peptidoglycan was LL-2,6-diaminopimelic acid. The predominant cell-wall sugars were composed of galactose, mannose, rhamnose and xylose. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, one unknown phospholipid and three unknown polar lipids. The DNA G+C content was 69.3 mol%. On the basis of phenotypic and chemotaxonomic characteristics and the results of phylogenetic analysis, BGMRC0092(T) represents a novel species of the genus Nocardioides, for which the name Nocardioides sonneratiae sp. nov. is proposed. The type strain is Nocardioides sonneratiae BGMRC0092(T) (=KCTC 39565(T) = NBRC 110251(T) = DSM 100390(T)).
