Fluviispira sanaruensis sp., nov., Isolated from a Brackish Lake in Hamamatsu, Japan.

Strain RF1110005, which was isolated from brackish lake water sampled at Lake Sanaru in Japan as a "filterable" bacterial strain, was characterized as a novel species in the genus Fluviispira, family Silvanigrellaceae, order Silvanigrellales, the class Oligoflexia and the phylum Bdellovibrionota. Cells of RF1110005 were aerobic, Gram stain negative, and show a pleomorphic morphology of spiral, filamentous and rod shapes. Catalase reaction was positive.
