Synonyms: according to Vancanneyt et al. 2005, Lactobacillus ferintoshensis Simpson et al. 2002, is a later heterotypic synonym of
Lactobacillus parabuchneri Farrow et al. 1989.
Gram-positive rods (0.8-1.0 x 2-4 µm), occuring single, in pairs, or in short chains.
Nonmotile.
After 48 h incubation on modified MRS agar (MRS agar supplemented with vitamins),
colonies are 2–5 mm in diameter, circular, shiny, and creamy white. Optimum growth
temperature 28 ºC. Can grow at 15 ºC, but not at 45 ºC.
Isolated from human saliva, cheese, and contaminated brewery yeasts.
Undetermined.

Obligately heterofermentative (hexoses are fermented to lactic acid, acetic acid (ethanol), and CO2 via the phosphogluconate pathway;
pentoses are fermented to lactic acid and acetic acid by the related pentose phosphate pathaway).
Positive results for arginine hydrolysis (NH3 from arginine), fermentation of: L-arabinose, fructose, galactose, D-glucose, gluconate,
maltose, mannose, melezitose, melibiose, raffinose, ribose, and sucrose.
Negative results for urease, Voges-Proskauer test, fermentation of: adonitol, amygdalin, D-arabitol, L-arabitol, arbutin, cellobiose,
dulcitol, erythritol, esculin, D-fucose, L-fucose, glycerol, glycogen, inositol, inulin, 2-ketogluconate, lactose, mannitol, methyl
alpha-D-glucoside, N-acetylglucosamine, rhamnose, salicin, sorbitol, sorbose, starch, trehalose, xylose, and D-lyxose.
Variable and weak results for 5-ketogluconate fermentation.
