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

Abstract

A strictly aerobic, non-motile, rod-shaped actinomycete strain, named JC2055(T), 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-9(T) (95-5%). The major menaquinone was MK-8(H-4) 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 JC2055(T) 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 JC2055(T) (=IMSNU 14028(T)=KCTC 9920(T)=JCM 12124(T)).
