Abstract

An aerobic, Gram-stain-negative, weak-motile, short-rod-shaped bacterial strain, designated JBR3-12, was isolated from halophyte plants, and its taxonomic position was investigated by using a polyphasic taxonomic approach. The strain produced a pink pigment on tryptic soy agar and grew optimally at 25 °C, pH 8 and in the presence of 3 % (w/v) NaCl. Results of phylogenetic analysis based on 16S rRNA gene sequences showed that strain JBR3-12 formed a lineage within the genus and was most closely related to DS-27 (98.0 %) and PB92 (97.6 %). The DNA G+C content of the genome was 41.3 mol%; the whole genome length was 5 426 070 bp. The major fatty acids of JBR3-12 were iso-C, summed feature 3 (comprising C 6 and/or C 7) and iso-C 3-OH. The predominant polar lipid was phosphatidylethanolamine. The predominant quinone was menaquinone-7. Based on its phenotypic, phylogenetic and genotypic features, strain JBR3-12 is proposed to represent a novel species of the genus , for which the name is sp. nov. The type strain is JBR3-12 (=KCTC 82363=NBRC 114901).
