Enterocloster alcoholdehydrogenati sp. nov., a Novel Bacterial Species Isolated from the Feces of a Patient with Alcoholism.

Strain C5-48, an anaerobic intestinal bacterium that potentially accumulates acetaldehyde at levels exceeding its minimum mutagenic concentration (50 µM) in the colon and rectum, was isolated from the feces of a patient with alcoholism. The 16S rRNA gene sequence of strain C5-48 showed high similarity to the corresponding sequences of Lachnoclostridium edouardi Marseille-P3397 (95.7%) and Clostridium fessum SNUG30386 (94.
