Paraperlucidibaca baekdonensis gen. nov., sp. nov., isolated from seawater.
A Gram-negative, non-spore-forming, rod-shaped bacterial strain, RL-2(T), was isolated from seawater of the East Sea in Korea and was subjected to a polyphasic taxonomic study. Strain RL-2(T) grew optimally at pH 7.5-8.0, at 20 °C and in the absence of NaCl. Phylogenetic trees based on 16S rRNA gene sequence analysis showed that strain RL-2(T) forms a cluster with Perlucidibaca piscinae IMCC1704(T) and various uncultured and unidentified gammaproteobacteria. Strain RL-2(T) exhibited 16S rRNA gene sequence similarity values of 96.1 % to Perlucidibaca piscinae IMCC1704(T) and 93.7-99.7 % to the uncultured bacterial clones belonging to the cluster and an unidentified gammaproteobacterium. The fatty acid profile of strain RL-2(T) was similar to that of Perlucidibaca piscinae IMCC1704(T), but the predominant ubiquinone type (Q-11) of strain RL-2(T) was different from that (Q-8) of Perlucidibaca piscinae IMCC1704(T). The DNA G+C content of strain RL-2(T) was 61.3 mol%. On the basis of phylogenetic, chemotaxonomic and phenotypic data, strain RL-2(T) is considered to represent a novel species of a new genus in the family Moraxellaceae, for which the name Paraperlucidibaca baekdonensis gen. nov., sp. nov. is proposed. The type strain of Paraperlucidibaca baekdonensis is RL-2(T) ( = KCTC 23145(T)  = CCUG 59307(T)).
