This organism was not found in clinically normal pigs. Because this organism had properties different from those of any previously described taxon, we propose that it be regarded as a new species, Acetivibrio ethanolgignens. The isolates of A. ethanolgignens were obligately anaerobic, gram-negative, nonsporeforming, motile, slightly curved rods with lateral flagella that emanated from the concave sides of the cells and formed fascicles. A. ethanolgignens differs from other species in the genus Acetivibrio principally in its inability to degrade cellulose or ferment cellobiose, its production of ethanol as a major fermentation product, and its possession of multiple flagella. The guanine-plus-cytosine content of its deoxyribonucleic acid is 40 mol%. The type strain is 77-6, a culture of which has been deposited in the American Type Culture Collection under the number ATCC 33324. We also emend the description of the genus Acetivibrio to include bacteria with multiple flagella.", }
