A novel, facultatively anaerobic bacterium (strain JAM-BA0501(T)) was isolated from a deep subseafloor sediment sample at a depth of 247 m below seafloor off the Shimokita Peninsula of Japan in the north-western Pacific Ocean (Site C9001, 1180 m water depth). Cells of strain JAM-BA0501(T) were gram-negative, filamentous, non-spore-forming and motile on solid medium by gliding. Phylogenetic analysis based on the 16S rRNA gene sequence of strain JAM-BA0501(T) indicated a distant relationship to strains representing genera within the order Bacteroidales, such as Alkaliflexus imshenetskii Z-7010(T) (91.1â% similarity), Marinilabilia salmonicolor ATCC 19041(T) (86.2â%) and Anaerophaga thermohalophila Fru22(T) (89.3â%). The new isolate produced isoprenoid quinones with menaquinone MK-7 as the major component, and the predominant fatty acids were iso-C(15â:â0) and anteiso-C(15â:â0). The DNA G+C content of the isolate was 42.9 mol%. Based on its taxonomic distinctiveness, strain JAM-BA0501(T) is considered to represent a novel species of a new genus within the family Marinilabiliaceae, for which the name Geofilum rubicundum gen. nov., sp. nov. is proposed. The type strain of Geofilum rubicundum is JAM-BA0501(T) (â=âJCM 15548(T) â=âNCIMB 14482(T)).
