| Abstract |
A Gram-negative, aerobic, non-motile, rod-shaped bacterial strain, designated as SWU8(T), was isolated from a mountain soil collected in Seoul Women's University campus at South Korea. Phylogenic analysis, using 16S rRNA gene sequence of the new isolate, showed that strain SWU8(T) belongs to the genus Pontibacter. The highest sequence similarities were 96.2 % with Pontibacter saemangeumensis GCM0142(T), 95.5 % with Pontibacter toksunensis ZLD-7(T), 95.3 % with Pontibacter roseus DSM 17521(T), and 95.1 % with Pontibacter odishensis JC130(T). Chemotaxonomic data showed that the most abundant fatty acids were summed feature 4 (comprising iso-C(17:1) I/anteiso-C(17:1) B; 26.9 %), iso-C(15:0) (25.6 %), and iso-C(17:0) 3OH (10.6 %), and major polar lipid was phosphatidylethanolamine. The DNA G+C content of strain SWU8(T) was 48.5 mol%. Together, the phenotypic, phylogenetic, and chemotaxonomic data supported that strain SWU8(T) presents a novel species of the genus Pontibacter, for which the name Pontibacter humi sp. nov. is proposed. The type strain is SWU8(T) (=KEMC 9004-131(T) = JCM 19178(T)).
