Homotypic synonym: Latilactobacillus graminis (Beck et al. 1989) Zheng et al. 2020.
Gram-positive, slightly curved rods with rounded ends, 0.7-1.0 x 1.5-2 µm, occurring
singly, in pairs, or short chains. Nonmotile.
Colonies are smooth, round, nonpigmented. Produce a flocculant sediment after 3
days of growth in MRS broth. Can grow at 15 ºC, but not at 45 ºC.
Habitat: grass silage.
Undetermined.

Facultatively heterofermentative (hexoses are fermented almost exclusively to lactic acid by the Embden-Meyerhof pathway or, at least
by some species, to lactic acid, acetic acid, ethanol, and formic acid under glucose limitations; pentoses are  fermented to lactic acid
and acetic acid via an inducible phosphoketolase).

Positive results for fermentation of: amygdalin, cellobiose, esculin, sucrose, and D-xylose.

Negative results for fermentation of: arabinose, dulcitol, gluconate, mannitol, melezitose, melibiose, raffinose, ribose, and sorbitol.
