The genus Anaerotaenia belongs to the family Lachnospiraceae within the order Clostridiales and contains one species, Anaerotaenia torta. Obligately anaerobic and chemoorganotrophic. Cells are Gram-stain-positive, slightly curved, or sigmoid long rods. Motile by peritrichous flagella. Spores are spherical and terminal. Saccharolytic and fermentative. Slightly alkaliphilic. Utilizes a wide variety of carbohydrates including xylan. Acetate, ethanol, and H2 are fermentation products from glucose. Catalase is absent. C16 :0, C18 :1 ω7c DMA, C18 :1 ω7c, and C16 :0 DMA are present as major CFAs. The cell-wall peptidoglycan contains meso-DAP as the diagnostic diamino acid. Isolated from a methanogenic reactor of livestock wastewater. Closely related species of Anaerotaenia torta are members of the genera Mobilitalea, Herbinix, and Anaerocolumna. These relatives were also isolated mainly from anaerobic reactors.

DNA G + C content (mol%): 47.2 (HPLC).
