Abstract

A Gram-stain-negative, rod-shaped, non-motile, aerobic, orange-pigmented, bacterium (designated 176CP4-71) was isolated from a sponge sample of from Cheongpo beach, Taean district, in the Republic of Korea. On the basis of 16S rRNA gene sequencing, strain 176CP4-71 clustered with species of the genus and appeared to be closely related to LMG 26637 (95.4 %), JCM 18450 (94.7 %), KACC 16195 (94.7 %) and KCTC 22339 (94.2 %). The average nucleotide identity values between strain 176CP4-71 and the closely related strains were 70.7–73.7 %, indicating that 176CP4-71 is a novel species of the genus . Growth occurs at 10–35 °C on marine agar medium in the presence of 1–8 % NaCl (w/v) and at pH 6.0–8.5. The DNA G+C content of the genomic DNA was 41.6 mol %, and menaquinone with six isoprene units (MK-6) was the major respiratory quinone. The major cellular fatty acids (>5 %) were Ciso, Ciso G, Ciso 3OH and Cω6 and/or Cω7 (summed feature 3). The polar lipids consisted of phosphatidylethanolamine, three unidentified aminophospholipids, an unidentified phospholipid and unidentified lipids. Physiological and biochemical characteristics indicated that strain 176CP4-71 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 176CP4-71 (=KACC 19889=LMG 31033).
