ABSTRACT
A novel bacterium, designated strain PS13T, was isolated from marine sediment collected from the coast of Jeju Island. Strain PS13T was a Gram stain-negative, catalase- and oxidase-positive, aerobic, yellow-pigmented, motile by gliding, and rod-shaped bacterium. Strain PS13T grew optimally at 25 °C and pH 8.0 and in the presence of 3â% (w/v) NaCl. Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain PS13T belonged to the genus Formosa and was closely related to Formosa algae KMM3553T (98.3â% sequence similarity). The DNA-DNA relatedness (17.3-21.8â%) and average nucleotide identity (83.6-84.6â%) values clearly indicated that strain PS13T represents a distinct species of the genus Formosa. The major fatty acids were C15ââ0 iso, C16ââ1 ω6c/C16ââ1 ω7c and C15ââ1 iso G. The genomic DNA G+C content of the strain PS13T was 32.2âmol%. On the basis of polyphasic characteristics, it is suggested that strain PS13T be assigned to the genus Formosa as the type strain of a novel species, for which the name Formosa sediminum PS13T (=KCCM 43301T=CECT 9918T) sp. nov. is proposed.
