Abstract

A novel Gram-reaction-negative, rod-shaped, aerobic and motile strain, designated MEBiC06469, was isolated from tidal flat sediment of the Taean province, South Korea. Strain MEBiC06469 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 KU41G 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 C 2-OH and/or Cω7; 20.4 %) and Cω8 (30.9 %), summed feature 8 (comprised of Cω7 and/or Cω6; 9.5 %), C (9.0 %), Cω8 (5.3 %), and C 3-OH (5.2 %). Based on these phenotypic properties and phylogenetic data, strain MEBiC06469 should be classified as a novel species within the genus for which the name sp. nov. is proposed. The type strain is MEBiC06469 ( = KCCM 42976 = JCM 18313). Emended descriptions of the genus , Iwaki 2014 , and Iwaki 2012 are also provided.
