RossYR 1984 T1 Emendation of the Genus Acetivibrio and Description of Acetivibrio cellulosolvens sp. nov., a Nonmotile Cellulolytic Mesophile† JF International Journal of Systematic and Evolutionary Microbiology, VO 34 IS 4 SP 419 OP 422 DO https://doi.org/10.1099/00207713-34-4-419 PB Microbiology Society, SN 1466-5034, AB The genus Acetivibrio is emended to include nonmotile, gram-negative, obligately anaerobic rods that produce acetic acid and ethanol from fermentation of carbohydrates. A new species, Acetivibrio cellulosolvens, which was isolated from a cellulose-enriched culture of sludge, is described. The colonies on agar are entire, raised, and cream colored. The cells are straight rods, gram-negative, nonsporeforming, and nonmotile. The isolate which we studied ferments cellobiose, cellulose, esculin, and salicin and does not require yeast extract or rumen fluid for growth. The major end products produced from cellobiose or cellulose are acetic acid, ethanol, CO2, and H2. Lactic acid and glucose also are produced in small amounts. The type strain of A. cellulosolvens is strains BAS (= NRC 2936)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-34-4-419
