A novel bacterium, designated strain PS13 T , was isolated from marine sediment collected from the coast of Jeju Island. Strain PS13 T was a Gram stain-negative, catalase- and oxidase-positive, aerobic, yellow-pigmented, motile by gliding, and rod-shaped bacterium. Strain PS13 T grew optimally at 25 °C and pH 8.0 and in the presence of 3 % (w/v) NaCl. Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain PS13 T belonged to the genus Formosa and was closely related to Formosa algae KMM3553 T (98.3 % sequence similarity). The DNA–DNA relatedness (17.3–21.8 %) and average nucleotide identity (83.6–84.6 %) values clearly indicated that strain PS13 T represents a distinct species of the genus Formosa . The major fatty acids were C 15 : 0 iso, C 16 : 1 ω 6 c /C 16 : 1 ω 7 c and C 15 : 1 iso G. The genomic DNA G+C content of the strain PS13 T was 32.2 mol%. On the basis of polyphasic characteristics, it is suggested that strain PS13 T be assigned to the genus Formosa as the type strain of a novel species, for which the name Formosa sediminum PS13 T (=KCCM 43301 T =CECT 9918 T ) sp. nov. is proposed.
