Synonym: Lactobacillus yamanashiensis subsp. mali (Carr and Davies 1970) Nonomura 1983, comb. nov.
Gram positive rods (0.5–0.8 x 1.2-1.3 μm) occurring singly, in pairs and in short
chains. Variable motility (peritrichous flagella). Nonspore-forming.
Colonies are white, smooth, and glistening after a few days; liquid cultures are turbid
after few days, with subsequent clearing and sediment. Facultatively anaerobic. Can
grow at 15 ºC. Variable growth at 45 ºC or in NaCl 6%. Can grow in pH 4.0.
Isolated from wine must, fermenting cider, and fermented molasses.
Undetermined.

Obligately homofermentative (hexoses are fermented almost exclusively to lactic acid
by the Embden-Meyerhof pathway; pentoses or gluconate are not fermented).
Positive results for fermentation of: amygdalin, arbutin, cellobiose, esculin, fructose, galactose, gentiobiose, glucose (acid but no gas
production), gluconate, inulin, mannitol, mannose, salicin, sucrose (dextran is produced), tagatose, trehalose and
N-acetylglucosamine.
Negative results for arginine hydrolysis, gelatin digestion, nitrate reduction, H2S, indole, lecithinase, lipase, urease, litmus milk,
fermentation of: adonitol, arabinose, dulcitol, erythritol, glycerol, glycogen, inositol, 5-ketogluconate, sorbitol, turanose, xylose and gas
production from citrate.
Variable results for catalase, esculin hydrolysis, Voges-Proskauer reaction, fermentation of: lactose, maltose, melezitose, melibiose,
raffinose, rhamnose, ribose and sorbose.
