A Gram-stain-negative, aerobic, rod-shaped and orange-coloured strain, designated LHR20T, was isolated from a marine solar saltern. The novel strain LHR20T was able to grow at 15-40 °C (optimum 33-37 °C), at pH 6.5-9.5 (optimum pH 7.5-8.0) and with 2.0-11.0 % (w/v) NaCl (optimum 4.0-5.0 %). MK-6 was the sole respiratory quinone, and the major fatty acids were iso-C15 : 0 and iso-C17 : 0 3-OH. The predominant polar lipids of strain LHR20T were phosphatidylethanolamine (PE), aminolipid (AL), glycolipid (GL1) and two unidentified lipids (L1, L2). The genomic DNA G+C content was 35.0 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain LHR20T was a member of the genus Brumimicrobium and its closest relative was Brumimicrobium mesophilum JCM 14063T (97.5 % sequence similarity). The average nucleotide identity value between strain LHR20T and B. mesophilum JCM 14063T was 73.7 %. This evidence from phenotypic, chemotaxonomic and phylogenetic analyses suggests that strain LHR20T represents a novel species of the genus Brumimicrobium. Therefore, the name Brumimicrobium salinarum sp. nov. is proposed. The type strain is LHR20T (=KCTC 62372T=MCCC 1H00247T).
