Nocardioides ganghwensis sp. nov., isolated from tidal flat sediment.

A strictly aerobic, non-motile, rod-shaped actinomycete strain, named JC2055T, was isolated from a sediment sample of getbol, the tidal flat of Korea. 16S rDNA analysis revealed that the getbol isolate belonged to the genus Nocardioides with the highest sequence similarity to Nocardioides aquiterrae GW-9T (95.5%). The major menaquinone was MK-8(H4) and the predominant cellular fatty acids were iso-16 : 0 and 17 : 1omega8c. Tuberculostearic acid was absent. The G+C content of DNA was 72 mol%. Based on the morphological, physiological, biochemical and chemotaxonomical data presented in this study, strain JC2055T can be readily differentiated from other validly named Nocardioides species. The name Nocardioides ganghwensis sp. nov. is proposed for the isolate. The type strain is JC2055T (=IMSNU 14028T=KCTC 9920T=JCM 12124T).
