A Gram-stain negative, non-motile, rod-shaped and aerobic bacterial strain, designated JG48T, was isolated from a gravel sample taken from a beach adjacent to Udo island, South Korea. Strain JG48T was found to grow optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. The 16S rRNA gene sequence of strain JG48T exhibited sequence similarities of 96.67 % to Hyunsoonleella jejuensis CNU004T. The major fatty acids present in the strain JG48T were identified as iso-C15:0, iso-C15:1 G, iso-C17:0 3–OH and iso-C15:0 3–OH. The predominant isoprenoid quinone was identified as MK-6. The polar lipids profile of strain JG48T was found to consist of phosphatidylethanolamine, three unidentified amino lipids and four unidentified lipids. The DNA G+C content of strain JG48T was determined to be 34 mol%. Based on the morphological and physiological properties, and the results of phylogenetic analyses, the strain is considered to represent a novel species of the genus Hyunsoonleella, for which the name Hyunsoonleella udoensis sp. nov. is proposed. The type strain is JG48T (=KCTC 42341T=JCM 30600T).
