Abstract

A novel bacterial strain, designated EC29, was isolated from the brown alga collected on Jeju Island, Republic of Korea. Cells of strain EC29 were Gram-stain-negative, aerobic, rod-shaped and motile by gliding. Growth was observed at 10–30 °C (optimum, 20–25 °C), at pH 6.0–9.5 (optimum, pH 7.5) and in the presence of 1–5 % (w/v) NaCl. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the strain belonged to the genus . Strain EC29 exhibited the highest 16S rRNA gene sequence similarities, of 96.5–97.8 %, to the type strains of EM106, KMM 6211 and KMM 6390. Strain EC29 exhibited < 27 % DNA–DNA relatedness with EM106 and KMM 6211. The predominant fatty acids of strain EC29 were iso-C, iso-C G, C, iso-C 3-OH, iso-C 3-OH and anteiso-C. The DNA G+C content was 31.1 mol% and the major respiratory quinone was menaquinone-6 (MK-6). Based on a polyphasic study, strain EC29 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is EC29 ( = KCTC 32172 = JCM 18703).
