Phylum Firmicutes, Class Bacilli, Order Lactobacillales, Family Lactobacillaceae, Genus Lactobacillus, [Group C lactobacilli
(obligately heterofermentative), unique phylogenetic group], Lactobacillus spicheri Meroth, Hammes and Hertel 2004.
Rods, 1.5 x 3.0-5.0 µm, occuring singly or in pairs, seldom in short chains. Nonmotile.
After 3 days of incubation on MRS5 agar, colonies are white, circular, smooth, and
0.5–1 mm in diameter. Can grow at 15 ºC, but not at 45 ºC. Can grow in pH 5.0. Can
grow in 5% NaCl media, not in 7% NaCl.
Isolated from an industrial processed rice sourdough.

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).
Fructose is reduced to mannitol.
Positive results for arginine hydrolysis (NH3 from arginine), fermentation of: L-arabinose, glucose
(weak reaction, but it is strong in combination with fructose), maltose, ribose, and D-xylose.
Negative results for catalase, fermentation of: D-arabinose, cellobiose, esculin, galactose, mannose, melezitose, melibiose,
raffinose, sucrose, trehalose, and L-xylose.
