Abstract

A novel Gram-stain-negative, rod-shaped, gliding, halotolerant, aerobic, light-pink-pigmented bacterium, strain JL3085, was isolated from surface water of the South China Sea (16° 49′ 4″ N 112° 20′ 24″ E; temperature: 28.3 °C, salinity: 34.5%). The major respiratory quinone was menaquinone 7 (MK-7). The polar lipids of strain JL3085 comprised phosphatidylethanolamine, four unidentified phospholipids and three unidentified lipids. The major fatty acids were iso-C15 : 0, summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1 ω7c), iso-C17 : 0 3-OH, iso-C17 : 1 ω9c, C17 : 1 ω6c, anteiso-C15 : 0 and C16 : 1 ω5c. The DNA G+C content of strain JL3085 was 43.8 mol%. 16S rRNA gene sequence analysis indicated that strain JL3085 was affiliated with the genus Echinicola , a member of the phylum Bacteroidetes , and was related most closely to Echinicola vietnamensis KMM 6221 (96.8 % similarity). DNA–DNA relatedness between strain JL3085 and E. vietnamensis KMM 6221 was 27.5 %. Based on the evidence presented here, strain JL3085 is regarded as representing a novel species of the genus Echinicola , for which the name Echinicola rosea sp. nov. is proposed. The type strain is JL3085 (=NBRC 111782=CGMCC 1.15407).
