Roseivivax lentus sp. nov., isolated from a tidal flat sediment, and emended description of the genus Roseivivax Suzuki et al. 1999.
A Gram-negative-staining, aerobic, non-motile and rod-shaped bacterial strain, S5-5(T), was isolated from a tidal flat sediment at Saemankum on the west coast of Korea and subjected to a polyphasic taxonomic investigation. Strain S5-5(T) grew optimally at pH 7.5-8.0, at 30 degrees C and in the presence of 2 % (w/v) NaCl. It did not produce bacteriochlorophyll a. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain S5-5(T) is phylogenetically closely related to the genus Roseivivax, joining the cluster comprising the two recognized Roseivivax species. The 16S rRNA gene sequence similarity between strain S5-5(T) and members of the genus Roseivivax was in the range 95.0-96.7 %. Strain S5-5(T) contained Q-10 as the predominant ubiquinone and C(18 : 1)omega7c and 11-methyl C(18 : 1)omega7c as the major fatty acids. The DNA G+C content was 68.2 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain S5-5(T) could be differentiated from Roseivivax species. On the basis of the data presented, strain S5-5(T) is considered to represent a novel species of the genus Roseivivax, for which the name Roseivivax lentus sp. nov. is proposed. The type strain is S5-5(T) (=KCTC 22708(T) =CCUG 57755(T)).
