Hymenobacter persicinus sp. nov., a novel member of the family Hymenobacteraceae Abstract A bacterial strain, 1-3-3-3T, was isolated from a soil sample collected in Jeollabuk-do province, South Korea. Cells were observed to be Gram-stain negative, short rod-shaped and colonies to be red-pink in colour. Analysis of 16S rRNA gene sequences identified this strain as a member of the genus Hymenobacter in the family Hymenobacteraceae, with high levels of 16S rRNA sequence similarity with Hymenobacter algoricola VUG-A23aT(98.0%), Hymenobacter knuensis 16F7C-2 (97.9%), Hymenobacter fastidiosus VUG-A124T (97.1%), Hymenobacter elongatus VUG-A112T (97.0%), Hymenobacter chitinivorans Txc1T (97.0%) and Hymenobacter aquaticus16F3PT (96.7%). Growth of strain 1-3-3-3T was observed at 10–30 °C, pH 6–8 and in the presence of 0–1.0% NaCl. The genomic G + C content was determined to be 61.6 mol %. The predominant respiratory quinone of the isolate was found to be MK-7; the major fatty acids were identified as iso-C15:0 (19.9%), summed feature 3 (C16:1ω7c/C16:1ω6c, 19.7%), summed feature 4 (iso-C17:1 I/anteiso-C17:1 B, 17.8%), C16:1ω5c (12.5%) and anteiso-C15:0 (11.2%), and the major polar lipid was found to be phosphatidylethanolamine. The phenotypic and chemotaxonomic data support the affiliation of strain 1-3-3-3T with the genus Hymenobacter. However, the DNA-DNA relatedness between the isolate and its closest phylogenetic neighbours was lower than 34%. The DNA–DNA hybridization result and the differentiating phenotypic properties clearly indicate that strain 1-3-3-3Trepresents a novel species in the genus Hymenobacter, for which the name Hymenobacter persicinus sp. nov. is proposed. The type strain is 1-3-3-3T (= KCTC 52742T = JCM 32191T).
