Optimum growth was observed at 50–55 °C, at pH 7.0 and with 0–1.5 % (w/v) NaCl. Phylogenetic analysis of the 16S rRNA gene sequence of strain YIM 78300T indicated that it belongs to the genus Brevibacillus. Similarity levels between the 16S rRNA gene sequences of the new isolate and those of the type strains of Brevibacillus members were 96.9–96.3 %; highest sequence similarity was with Brevibacillus thermoruber DSM 7064T. The predominant menaquinone was MK-7 and the major cellular fatty acids were iso-C15 : 0 and iso-C17 : 0. The major polar lipids were phosphatidyl-N-methylethanolamine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, two unidentified phospholipids, an unidentified aminophospholipid and two unidentified polar lipids. The G+C content of the genomic DNA of strain YIM 78300T was 57.9 mol%. Based on phylogenetic analyses, and physiological and biochemical characteristics, strain YIM 78300T is considered to represent a novel species of the genus Brevibacillus, for which the name Brevibacillus sediminis sp. nov. is proposed. The type strain is YIM 78300T ( = DSM 29928T = CPCC 100738T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.000752
