title: Filimonas lacunae gen. nov., sp. nov., a member of the phylum Bacteroidetes isolated from fresh water.
abstract: A Gram-negative, strictly aerobic, motile, filamentous and viscous exopolymer-producing bacterium, designated strain YT21(T), was isolated from fresh water. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain YT21(T) lies within a cluster containing the established genera Segetibacter, Terrimonas, Niastella and Chitinophaga in the phylum Bacteroidetes. However, the isolate represented a lineage distinct from these genera, with sequence similarities ranging from 88.9 to 91.8 %. The genomic G+C content was 45.2 mol%. The predominant isoprenoid quinone was MK-7. The major fatty acids were 15 : 0 iso, 17 : 0 iso 3-OH and 15 : 1 iso G. On the basis of morphological features and phenotypic and phylogenetic data, strain YT21(T) represents a novel genus and species, for which the name Filimonas lacunae gen. nov., sp. nov. is proposed. The type strain of Filimonas lacunae is strain YT21(T) (=NBRC 104114(T) =DSM 21054(T)).
