title: Perlucidibaca piscinae gen. nov., sp. nov., a freshwater bacterium belonging to the family Moraxellaceae.
abstract: A freshwater bacterium, designated IMCC1704(T), was isolated from a eutrophic pond. The strain was Gram-negative, oxidase-positive, catalase-negative, chemoheterotrophic and facultatively aerobic with cells that were motile rods with a single polar flagellum. Based on 16S rRNA gene sequence similarity analyses, the novel strain was most closely related to the genera Alkanindiges (91.7%), Acinetobacter (89.0-91.2%), Moraxella (87.9-90.1%), Psychrobacter (87.2-89.5%) and Enhydrobacter (87.8%). Phylogenetic trees generated using 16S rRNA gene sequences showed that the novel isolate belonged to the family Moraxellaceae of the class Gammaproteobacteria and formed a distinct phyletic lineage within the family. The DNA G+C content of the strain was 63.1 mol% and the predominant constituents of the cellular fatty acids were C(16:1)omega7c and/or iso-C(15:0) 2-OH (21.2%), C(18:1)omega7c (12.8%) and C(12:0) 3-OH (12.3%). These chemotaxonomic properties, together with several phenotypic characteristics, differentiated the novel strain from other members of the family Moraxellaceae. From the taxonomic data, which revealed the distant relationship of the new strain to the related genera, the strain should be classified as a novel genus and species in the family Moraxellaceae, for which the name Perlucidibaca piscinae gen. nov., sp. nov. is proposed. The type strain of Perlucidibaca piscinae sp. nov. is IMCC1704(T) (=KCCM 42363(T)=NBRC 102354(T)).
