Abstract:
A novel Gram-stain-negative, rod-shaped, gliding, halotolerant, aerobic, light-pink-pigmented bacterium, strain JL3085T, 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 JL3085T 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 : 1ω7c), iso-C17 : 0 3-OH, iso-C17 : 1ω9c, C17 : 1ω6c, anteiso-C15 : 0 and C16 : 1ω5c. The DNA G+C content of strain JL3085T was 43.8 mol%. 16S rRNA gene sequence analysis indicated that strain JL3085T was affiliated with the genus Echinicola, a member of the phylum Bacteroidetes, and was related most closely to Echinicola vietnamensis KMM 6221T (96.8 % similarity). DNA-DNA relatedness between strain JL3085T and E. vietnamensis KMM 6221T was 27.5 %. Based on the evidence presented here, strain JL3085T 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 JL3085T (=NBRC 111782T=CGMCC 1.15407T).
