title: Pelagitalea pacifica gen. nov., sp. nov., a new marine bacterium isolated from seawater.
abstract: A strictly aerobic, Gram-negative, beige-pigmented, short-rod-shaped, non-motile and chemoheterotrophic bacteria, designated K2-48(T) was isolated from seawater collected in the Western North Pacific Ocean near Japan. Preliminary analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the family Oceanospirillaceae within the class Gammaproteobacteria and that it showed the highest sequence similarity (93.7 %) to Neptunomonas qingdaonensis P10-2-4(T). The strain could be differentiated phenotypically from recognized members of the family Oceanospirillaceae. The major fatty acids of strain K2-48(T) were identified as summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH) and C16:0 as defined by the MIDI system. The DNA G+C content was determined to be 43.2 mol%, the major respiratory quinone was identified as ubiquinone 9 and a polar lipid profile was present consisting of phosphatidylethanolamine, a phosphatidylglycerol and an unidentified phospolipid. On the basis of polyphasic taxonomic studies, it was concluded that strain K2-48(T) represents a novel genus sp. We propose the name Pelagitalea pacifica gen. nov., sp. nov. for this strain; its type strain is K2-48(T) (=KCCM 90119(T)).
