The genus Serinibacter belongs, based on the phylogenetic analysis of the nearly full-length 16S rRNA gene, to the Beutenbergiaceae together with the genera Beutenbergia, Salana, and Miniimonas. The two species of the genus Serinibacter shared 99.6% 16S rRNA gene sequence similarity but low DNA DNA relatedness. Cells are irregular rods, Gram-stain positive, not acid-fast. Endospores are not formed. Nonmotile. Aerobic to anaerobic. Oxidase-negative, catalase-positive. The peptidoglycan type is A4a with an l-Ser residue at position 1 of the peptide subunit. The acyl type is acetyl. The major cell-wall sugar is galactose. The predominant menaquinone is MK-8(H4). The major polar lipids consist of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, and unidentified phospholipids. Phosphatidylethanolamine is absent. The cellular fatty acid profile is dominated by the occurrence of iso- and anteiso-branched-chain acids. Mycolic acids are absent. The genomic G+C content is 70.7 to 72.8 mol%.
