title: Lentisphaera profundi sp. nov., isolated from deep-sea water.
abstract: A Gram-staining-negative, aerobic, non-motile, coccus-shaped bacterium, designated SAORIC-696T, was isolated from deep-sea water at a depth of 1700 m in the western North Pacific Ocean. Optimal growth of strain SAORIC-696T was observed at 15 °C, pH 7.0 and in the presence of 2 % (w/v) NaCl. Strain SAORIC-696T formed a robust phylogenetic clade with members of the genus Lentisphaera. The 16S rRNA gene sequence similarity showed that strain SAORIC-696T was most closely related to Lentisphaera marina (98.0 % similarity) and Lentisphaera araneosa (97.3 %). The DNA-DNA relatedness between SAORIC-696T and two species of the genus Lentisphaera was only 27-42 %. The DNA G+C content of strain SAORIC-696T was 43.1 mol% and predominant cellular fatty acids were C16 : 1ω9c (36.8 %), C14 : 0 (22.5 %) and C14 : 0 3-OH and/or iso-C16 : 1 I (10.8 %). Strain SAORIC-696T contained MK-7 as the only respiratory quinone. On the basis of taxonomic data collected in this study, it was concluded that strain SAORIC-696T represents a novel species of the genus Lentisphaera, for which the name Lentisphaera profundi sp. nov. is proposed, with the type strain SAORIC-696T ( = NBRC 110692T = KCTC 42681T).
