Lutibacter maritimus sp. nov., isolated from a tidal flat sediment.
A Gram-staining-negative, aerobic, non-motile, non-gliding, yellow-pigmented and rod-shaped bacterial strain, designated S7-2(T), was isolated from a tidal flat sediment at Saemankum on the west coast of Korea and investigated using a polyphasic taxonomic approach. Strain S7-2(T) grew optimally at pH 7.0-8.0, at 25-30 degrees C and in the presence of 2 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain S7-2(T) clustered with Lutibacter litoralis CF-TF09(T), a member of the family Flavobacteriaceae, with which it showed 95.8 % 16S rRNA gene sequence similarity. It contained MK-6 as the predominant menaquinone and iso-C(15 : 0) and C(15 : 1) omega6c as the major fatty acids. The major polar lipids of strain S7-2(T) and L. litoralis JCM 13034(T) were phosphatidylethanolamine and three unidentified lipids. The DNA G+C content was 34.6 mol%. Differential phenotypic properties and phylogenetic distinctiveness suggested that strain S7-2(T) represents a novel species of the genus Lutibacter, for which the name Lutibacter maritimus sp. nov. is proposed. The type strain is S7-2(T) (=KCTC 22635(T)=CCUG 57524(T)).
