Abstract
A Gram-stain-positive, non-motile, strictly aerobic, non-spore-forming and short rod-shaped bacterial strain, CL-GY44T, was isolated from coastal seawater, Korea. Analysis of the 16S rRNA gene sequence of strain CL-GY44T revealed a clear affiliation with the genus
Nocardioides
. Based on phylogenetic analysis, strain CL-GY44T showed the closest phylogenetic relationship with
Nocardioides ginsengagri
BX5-10T and
Nocardioides plantarum
NCIMB 12834T. Strain CL-GY44T was not able to grow in the presence of NaCl but grew with 0–5.5 % sea salts. The optimum temperature and pH for growth were 30 °C and pH 7.0. The major cellular fatty acids of strain CL-GY44T were C17 : 1ω6c, iso-C16 : 0, C16 : 0 and iso-C15 : 0 and the major menaquinone was MK-8(H4). The cell-wall analysis showed that strain CL-GY44T contained ll-diaminopimelic acid. The genomic DNA G+C content was 71.6 mol%. The combined phenotypic, chemotaxonomic and phylogenetic data showed that strain CL-GY44T could be clearly distinguished from members of the genus
Nocardioides
. Thus, strain CL-GY44T should be classified as representing a novel species in the genus
Nocardioides
, for which the name Nocardioides marinquilinus sp. nov. is proposed. The type strain is CL-GY44T ( = KCCM 90109T = JCM 18459T).
