A Gram-staining-positive, aerobic, motile bacterium, designated strain MJ3T, was isolated from myeolchi-jeot (anchovy jeotgal), a traditional fermented seafood in South Korea. Cells were non-endospore-forming cocci showing catalase- and oxidase-positive reactions. Growth of strain MJ3T was observed at 15–45 °C (optimum, 30 °C), at pH 6.0–9.0 (optimum, pH 7.0–8.0) and in the presence of 1–24 % (w/v) NaCl (optimum, 10 % NaCl). Phylogenetic inference based on 16S rRNA gene sequences showed that strain MJ3T formed a tight phyletic lineage with members of the genus Salimicrobium . Strain MJ3T was related most closely to Salimicrobium salexigens 29CMIT, Salimicrobium album DSM 20748T, Salimicrobium flavidum ISL-25T, Salimicrobium luteum BY-5T and Salimicrobium halophilum DSM 4771T, with similarities of 98.8 %, 98.7 %, 98.6 %, 98.4 % and 98.3 %, respectively. However, the DNA–DNA relatedness values between strain MJ3T (KF732837) and S. salexigens DSM 22782T, S. album DSM 20748T, S. flavidum DSM 23127T, S. luteum KCTC 3989T and S. halophilum JCM 12305T were 60±5.4 %, 58.5±6.5 %, 43.6±5.5 %, 37.2±5.8 % and 16.7±0.2 %, respectively. Chemotaxonomic data (sole isoprenoid quinone, MK-7; major cell-wall type, meso-diaminopimelic acid; major cellular fatty acids, anteiso-C15 : 0, anteiso-C17 : 0 and iso-C15 : 0; major polar lipids, phosphatidylglycerol and diphosphatidylglycerol; DNA G+C content, 46.3 mol%) also supported the affiliation of strain MJ3T with the genus Salimicrobium . Therefore, strain MJ3T represents a novel species of the genus Salimicrobium , for which the name Salimicrobium jeotgali sp. nov. is proposed. The type strain is MJ3T ( = KACC 16972T = JCM 19758T).
