Palleronia soli sp nova, isolated from a soil sample on reclaimed tidal land, and emended description of the genus Palleronia

초록

A Gram-stain-negative, strictly aerobic, non-motile, non-spore-forming, short rod-shaped and moderately halophilic bacterial strain, CAU 1105(T), was isolated from soil on reclaimed tidal land in Modo, Republic of Korea, and its taxonomic position was investigated using a polyphasic approach. Strain CAU 1105(T) grows optimally at a temperature of 37 degrees C at pH 7 in the presence of 3% (w/v) sea salt. Based on 16S rRNA gene sequence similarity analyses, the novel isolate was assigned to the genus Palleronia within the class Alphaproteobacteria and showed the highest 16S rRNA gene sequence similarity with Palleronia marisminoris B33(T) (95.4 Wo). Strain CAU 1105(T) contained ubiquinone-10 as the only respiratory quinone and C-18:1 omega 7c as the major cellular fatty acid. The DNA G+C content of strain CAU 1105(T) was 64.3 mol%. On the basis of phenotypic differentiation, phylogenetic and chemotaxonomic data, strain CAU 1105(T) represents a novel species of the genus Palleronia, for which the name Palleronia soli sp. nov. is proposed. The type strain is CAU 1105(T) (=KCTC 42298(T)=NBRC 110740(T)). An emended description of the genus Palleronia is also provided.
