Pontibacter salisaro sp. nov., Isolated from a clay tablet solar saltern in Korea

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°59′47″N 126°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 30H (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 ).
