Cells are curved rods or spirals exhibiting a Gram-stain-negative cell wall. Motile, but motility may be lost in culture. Endospores are not formed. Obligately anaerobic. Chemo-organotrophic. Catalase-negative. Cytochrome b and the modified naphthoquinone, “lipid F”, with octa-and nonaprenologues (ratio 1:2) as the predominating isoprenologues, are present. Mesophilic. Phosphatidyl serine and phosphatidyl ethanolamine are the major polar lipids. Major fatty acids are C15:1, C15:0, C17:1, and C17:0, and, of the hydroxy fatty acids, C11:0 3OH, C12:0 3OH, and C13:0 3OH dominate.
DNA G+C content (mol%): ~35.
