Synonyms: Lactobacillus plantarum var. mobilis isolated from feces of turkey (Harrison
and Hansen, 1950) may belong to Lactobacillus agilis (Sharpe et al., 1973).
Rods with rounded ends, 0.7-1.0 x 3-6 µm, occuring singly, in pairs and in short
chains. Motile by peritrichous flagella. Nonsporeforming.
No growth at 15 ºC. Can grow at 45 ºC.
Isolated from municipal sewage; habitat is the crop of pigeons.

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, mannitol, melezitose, melibiose, raffinose, ribose, nd sucrose.
Negative results for arginine hydrolysis, fermentation of: arabinose, gluconate, and xylose.
Variable results for sorbitol fermentation.
