Spherical cells with Gram-negative cell structure. Gram-stain-negative. Motile by means of a single flagellum. Facultative anaerobes capable of aerobic growth on peptone and yeast extract. Ferment monosaccharides or disaccharides for carbon and energy. Ferment glucose primarily to butyrate, together with propionate or formate. Lactate and acetate also produced. No gas produced. Do not ferment peptides. Agarolytic. Oxidase- and catalase-positive. Moderately thermophilic, growing at 40-56°C but not 30 or 60°C. Slightly halophilic, growing in media containing l-3% NaCI but not in those containing 0 or 5% NaCl. Require sodium. C15:0 anteiso is the most abundant cellular fatty acid. Phylogenetically, the genus belongs to the order opitutales in the phylum Verrucomicrobia. Isolated from two hot springs in the intertidal zone of Lutao, Taiwan, based on their ability to hydrolyze agar in an agar-solidified marine medium.
