Matthies et al. 2005. Type species of the genus.
Gram-positive, 0.7 x 1.0 μm, ovoid cells, containing multiple cell-wall layers and
intracellular membranes. Grouping mostly in pairs. Non-motile (no flagella).
Endospores are not formed.
Anaerobic with an aerotolerant, chemo-organotrophic, fermentative metabolism.
Grows at pH 3.5-7.5 and 0-35 ºC. Doubling time is 4.7 h at pH 6.3 and 25 ºC. Cell
lysis is minimal in broth cultures.
Isolated from an acidic forest floor (L horizon) solution obtained from a beech forest in east-central Germany.
Undetermined.
Catalase and NADH oxidase negative.
Grows on glucose, galactose, fructose, mannitol, glucosamine, N-acetylglucosamine, cellobiose, and maltose. Lactate, ethanol,
formate, and acetate are the end products of fermentation. Minor amounts of CO2 are produced.
