Popis: | A yellow-pigmented, Gram-stain-negative and facultatively anaerobic bacterium, designated FB218T, was isolated from a sediment sample collected from a sea cucumber culture pond in Rongcheng, China (36° 54′ 36″ N 122° 14′ 34″ E). Cells of strain FB218T were slender, gliding, catalase-positive and oxidase-negative. Optimal growth occurred at 30 °C, pH 6.5–7.0 and in medium containing 2–3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain FB218T belonged to the genus Carboxylicivirga, family Marinilabiliaceae. The predominant fatty acids were iso-C15 : 0 and anteiso-C15 : 0. MK-7 was the main respiratory quinone. The major polar lipids of strain FB218T were two unidentified lipids and a phospholipid. The genomic DNA G+C content was 40.0 mol%. Based on the distinct phylogenetic position and the combination of physiological and phenotypic characteristics, strain FB218T represents a novel species of the genus Carboxylicivirga, for which the name Carboxylicivirga linearis sp. nov. is proposed. The type strain is FB218T ( = KCTC 42254T = MCCC 1H00106T). An emended description of the genus Carboxylicivirga is also provided. |
