title: Pseudomaricurvus alcaniphilus sp. nov., a marine bacterium isolated from tidal flat sediment and emended descriptions of the genus Pseudomaricurvus, Pseudomaricurvus alkylphenolicus Iwaki et al. 2014 and Maricurvus nonylphenolicus Iwaki et al. 2012.
abstract: A novel Gram-reaction-negative, rod-shaped, aerobic and motile strain, designated MEBiC06469T, was isolated from tidal flat sediment of the Taean province, South Korea. Strain MEBiC06469T produced ivory-coloured colonies on marine agar 2216 medium and could degrade carboxymethyl-cellulose. On the basis of 16S rRNA gene sequence similarity, the closest relative was Pseudomaricurvus alkylphenolicus KU41GT with 96.5 % similarity. The isolate was catalase-positive but oxidase-negative. Growth was observed at 16-38 °C (optimum, 32 °C), at pH 6.0-9.0 (optimum, pH 7.5) and in the presence of 0.0-8.0 % (w/v) NaCl (optimum, 1.5 %). The only isoprenoid quinone was Q-8.The dominant fatty acids were summed feature 3 (comprised of C15 : 0 2-OH and/or C16 : 1ω7c; 20.4 %) and C17 : 1ω8c (30.9 %), summed feature 8 (comprised of C18 : 1ω7c and/or C18 : 1ω6c; 9.5 %), C16 : 0 (9.0 %), C15 : 1ω8c (5.3 %), and C11 : 0 3-OH (5.2 %). Based on these phenotypic properties and phylogenetic data, strain MEBiC06469T should be classified as a novel species within the genus Pseudomaricurvus for which the name Pseudomaricurvus alcaniphilus sp. nov. is proposed. The type strain is MEBiC06469T ( = KCCM 42976T = JCM 18313T). Emended descriptions of the genus Pseudomaricurvus, Pseudomaricurvus alkylphenolicusIwaki et al. 2014, and Maricurvus nonylphenolicusIwaki et al. 2012 are also provided.
