Gram-negative, straight or slightly curved rods, 0.4-0.6 x 1.8-4.8 µm. Motile by a few
flagella at a polar attachament point (lophotrichously flagellated). Spores are oval,
terminally located.
Colonies are glossy white in colour on solid agar containing cellobiose as a carbon
source. Colony formation is observed under anaerobic conditions. Obligately
anaerobic, thermophilic and chemo-organotrophic. Grow in 0-1.5% NaCl , optimum in
1.0% NaCl medium. Grow at 50-70 ºC, optimally at 60 ºC. Optimum pH 6.5; range
6.0-8.0. Fermentation products are hydrogen, carbon dioxide, acetate, lactate and
ethanol.
Isolated from anaerobic sludge of a cellulose-degrading methanogenic bioreactor.
Undetermined.
