sp. nov., a starch-degrading bacterium isolated from marine sediment Free

Abstract

A novel bacterium, designated strain PS13, was isolated from marine sediment collected from the coast of Jeju Island. Strain PS13 was a Gram stain-negative, catalase- and oxidase-positive, aerobic, yellow-pigmented, motile by gliding, and rod-shaped bacterium. Strain PS13 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 belonged to the genus and was closely related to KMM3553 (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 represents a distinct species of the genus . The major fatty acids were C iso, C 6/C 7 and C iso G. The genomic DNA G+C content of the strain PS13 was 32.2 mol%. On the basis of polyphasic characteristics, it is suggested that strain PS13 be assigned to the genus as the type strain of a novel species, for which the name PS13 (=KCCM 43301=CECT 9918) sp. nov. is proposed.
