Abstract:
A Gram-negative, non-spore-forming, aerobic, non-flagellated and rod- or oval-shaped bacterial strain, BB-MW24(T), was isolated from a coastal sediment in South Korea. Strain BB-MW24(T) grew optimally at 30-37 °C, at pH 7.0-7.5 and in the presence of 2.0-3.0% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain BB-MW24(T) clustered with Ponticoccus litoralis CL-GR66(T) and Roseivivax lentus S5-5(T), with which it exhibited 96.0 and 96.2% 16S rRNA gene sequence similarity, respectively. Strain BB-MW24(T) exhibited 85.2% gyrB sequence similarity with Sagittula stellata DSM 11524(T) and 83.3 and 83.2% gyrB sequence similarity with P. litoralis DSM 18986(T) and R. lentus S5-5(T), respectively. Strain BB-MW24(T) contained Q-10 as the predominant ubiquinone and C18:1ω7c as the predominant fatty acid. The polar lipid profile in strain BB-MW24(T) was similar to those of members of the genera Ponticoccus and Roseivivax, but one unidentified phospholipid was found as a major polar lipid only in strain BB-MW24(T). The DNA G+C content was 68.9 mol%. The phylogenetic data and differential chemotaxonomic and phenotypic properties revealed that strain BB-MW24(T) represents a novel species in a new genus within the class Alphaproteobacteria, for which the name Litorisediminicola beolgyonensis gen. nov., sp. nov. is proposed; the type strain of Litorisediminicola beolgyonensis is BB-MW24(T) (=KCTC 32139(T) =CCUG 62953(T)).
