Abstract
- A Gram-stain-negative, aerobic, non-flagellated, motile by gliding and ovoid or rod-shaped bacterial strain, designated YKTF-7T, was isolated from a tidal flat sediment on the Yellow Sea, South Korea. Strain YKTF-7T grew optimally at pH 7.0-8.0, at 30-37 °C and in the presence of 0.5-2.0 % (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain YKTF-7T fell within the clade comprising the type strains of species of the genus Pontibacter, clustering with the type strains of Pontibacterodishensis and Pontibacterkorlensis with which it exhibited 98.0-98.7 % sequence similarity. Strain YKTF-7T exhibited 16S rRNA gene sequence similarities of 94.7-96.8 % to the type strains of the other species of the genus Pontibacter and of less than 91.7 % to those of other recognized species. Strain YKTF-7T contained MK-7 as the predominant menaquinone and summed feature 4 (iso-C17 : 1 I and/or anteiso-C17 : 1 B) and iso-C15 : 0 as the major fatty acids. The major polar lipids were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain YKTF-7T was 54.0 mol%, and its mean DNA-DNA relatedness values with the type strains of P. odishensis and P. korlensis were 25 and 14 %, respectively. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that strain YKTF-7T is separated from recognized species of the genus Pontibacter. On the basis of the data presented, strain YKTF-7T is considered to represent a novel species of the genus Pontibacter, for which the name Pontibacterlitorisediminis sp. nov. is proposed. The type strain is YKTF-7T(=KCTC 52252T=NBRC 112298T).
