A Gram-negative, non-motile, rod-shaped bacterial strain, SMK-108T, was isolated from a tidal flat of the Yellow Sea in Korea and was subjected to a polyphasic taxonomic investigation. Strain SMK-108T grew optimally at pH 7.0-8.0 and at 30 °C. It contained MK-6 as the predominant menaquinone. The major fatty acids were iso-C17:0 3-OH, iso-C15:1 and iso-C15:0. The DNA G+C content was 41.1 mol%. Comparative 16S rRNA gene sequence analysis showed that strain SMK-108T was related most closely to members of the genus Muricauda, exhibiting 96.6-98.8% sequence similarity to the type strains of recognized Muricauda species. Strain SMK-108T was distinguishable from recognized Muricauda species on the basis of differential phenotypic characteristics, levels of DNA-DNA relatedness and phylogenetic distinctiveness. This organism is thus considered to represent a novel species of the genus Muricauda, for which the name Muricauda lutimaris sp. nov. is proposed. The type strain is SMK-108T (=KCTC 22173T =CCUG 55324T).
