Gram-positive, straight to slightly curved rods, 0.5 x 4.0-6.0 µm. Motile by peritrichous
flagella. Spores are oval, terminal, swelling the cell.
flagella. Spores are oval, terminal, swelling the cell.
Deep colonies in roll tubes are small, circular, and slightly yellow. On agar surface
colonies are widespread. Obligate anaerobe. Optimum temperature for growth is 37
ºC; range 20-48 ºC. End products of fermentation are ethanol, acetate, hydrogen, and
CO2. No growth factors required. Growth is enhanced by the addition of yeast extract,
biotrypcase, or vitamins.

Isolated from gut of wood-feeding termite (Nasutitermes lujae) from Mayombe tropical rainforest, Congo, Central Africa.

Positive results for hydrogen production, substrate utilization and/or acid production
from: cellobiose, cellulose, fructose, galactose, glucose, glycerol (weak), lactose,
maltose, mannitol, mannose, melibiose, ribose, sorbitol, sorbose and xylose.
Negative results for substrate utilization and/or acid production from: adonitol, arabinose, dulcitol, melezitose, raffinose, rhamnose,
