| Abstract |
A Gram-negative, aerobic, non-motile, and rod-shaped bacterium, designated strain DS48-5-3(T), was isolated from a 48 m sediment sample taken from Daechung Reservoir, Republic of Korea. Comparative 16S rRNA gene sequence studies showed a clear affiliation of this strain to the Bacteroidetes, notably most closely related to Ferruginibacter alkalilentus HU1-GD23(T), Ferruginibacter lapsinanis HU1-HG42(T) and Ferruginibacter yonginensis HME8442(T), showing 16S rRNA gene sequence similarities to the type strains of these species of 95.2-96.4 % similarity. The predominant ubiquinone was identified as MK-7. The major fatty acids were identified as iso-C15:0, iso-C17:0 3-OH, and iso-C15:1 G. The G+C content of the genomic DNA of strain DS48-5-3(T) was determined to be 37.2 %. On the basis of polyphasic evidence, it is proposed that strain DS48-5-3(T) should belong to a novel species, for which the name Ferruginibacter profundus sp. nov. (type strain DS48-5-3(T) = KCTC 32478(T) = JCM 19431(T)), is proposed.
