Marinobacterium marisflavi sp. nov., isolated from a costal seawater.
A marine bacterium designated strain IMCC4074(T) was isolated from surface seawater collected off Incheon Port, the Yellow Sea, and subjected to a polyphasic taxonomy. The strain was Gram-negative, chemoheterotrophic, slightly halophilic, strictly aerobic, and motile rods. Based on 16S rRNA gene sequence comparisons, the strain was most closely related to Marinobacterium litorale KCTC 12756(T) (93.9%) and shared low 16S rRNA gene sequence similarities with members of the genus Marinobacterium (91.8-93.9%) and the genus Neptunomonas (93.4%) in the order Oceanospirillales. Phylogenetic analyses showed that this marine isolate formed an independent phyletic line within the genus Marinobacterium clade. The DNA G+C composition of the strain was 56.0 mol% and the predominant constituents of the cellular fatty acids were C(16:0) (28.0%), C(16:1 )omega7c and/or iso-C(15:0) 2-OH (19.3%), C(18:1 )omega7c (17.8%), and C(17:1) cyclo (12.5%), which differentiated the strain from other Marinobacterium species. Based on the taxonomic data collected in this study, only a distant relationship could be found between strain IMCC4074(T) and other members of the genus Marinobacterium, thus the strain represents a novel species of the genus Marinobacterium, for which the name Marinobacterium marisflavi sp. nov. is proposed. The type strain of Marinobacterium marisflavi is IMCC4074(T) (= KCTC 12757(T) = LMG 23873(T)).
