Abstract
A Gram-stain-negative, aerobic, motile and rod-shaped bacterial strain, designated WT-RY4T, was isolated from wood falls in the South Sea, South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain WT-RY4T grew optimally at 25 °C, at pH 7.0–7.5 and in the absence of NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain WT-RY4T clustered with the type strain of Paraperlucidibaca baekdonensis with a bootstrap resampling value of 100 %. Strain WT-RY4T exhibited 16S rRNA gene sequence similarity values of 98.8 % and 96.3 % to Paraperlucidibaca baekdonensis RL-2T and Perlucidibaca piscinae IMCC 1704T, respectively and less than 91.5 % to the type strains of other species used in the phylogenetic analysis. The DNA G+C content of strain WT-RY4T was 52.4 mol% and the mean DNA–DNA relatedness value with Paraperlucidibaca baekdonensis RL-2T was 25 %. Strain WT-RY4T contained Q-11 as the predominant ubiquinone and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and C12 : 0 3-OH as the major fatty acids. Differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, demonstrated that strain WT-RY4T was distinguishable from Paraperlucidibaca baekdonensis RL-2T. On the basis of the data presented, strain WT-RY4T is considered to represent a novel species of the genus Paraperlucidibaca , for which the name Paraperlucidibaca wandonensis sp. nov. is proposed. The type strain is WT-RY4T ( = KCTC 32216T = CCUG 63419T). An emended description of the genus Paraperlucidibaca is also provided.
