Pontibacter salisaro sp. nov., Isolated from a Clay Tablet Solar Saltern in Korea

다국어 초록 (Multilingual Abstract)

A Gram-negative, aerobic, rod-shaped, and red-pigmented bacterial strain, $HMC5104^T$, was isolated from a solar saltern, found in Jeungdo, Republic of Korea ($34^{\circ}$59'47"N $126^{\circ}$10'02"E). The major fatty acids were summed feature 4 (comprising iso-$C_{17:1}$ I and/or anteiso-$C_{17:1}$ B; 37.2%), iso-$C_{15:0}$ (20.4%), and iso-$C_{17:0}$ 3OH (15.3%). The DNA G+C content was 46.0 mol%. The major isoprenoid quinone was menaquinone-7 (MK-7). A phylogenetic tree based on 16S rRNA gene sequences showed that strain $HMC5104^T$ formed a lineage within the genus Pontibacter, and was closely related to Pontibacter korlensis (95.9%), P. roseus (94.9%), and P. actiniarum (94.3%). Similarities to all other Pontibacter species were between 95.9-93.9%. On the basis of the evidence presented in this study, strain $HMC5104^T$ represents a novel species of the genus Pontibacter, for which the name Pontibacter salisaro sp. nov. is proposed. The type strain is $HMC5104^T$ (=KCTC $22712^T$ =NBRC $105731^T$).
