Synonyms:
Lactobacillus cypricasei  Lawson et al. 2001, Ligilactobacillus acidipiscis (Tanasupawat et al. 2000) Zheng et al. 2020.
Gram-positive rods, 0.4-0.6 x 1.2-5.0 µm, occuring singly, in pairs and in short chains.
Nonmotile. Nonsporeforming.
Colonies on MRSH agar plate are circular, slightly convex with an entire margin, and
nonpigmented. Requires niacin and calcium pantothenate for growth.
Microaerophilic. Growth temperature is 25-37 ºC. No growth at 15 or 42 ºC. No growth
at pH 4.0 or 8.5. Can grow in 10 and 12% NaCl.
Isolated from fermented fish ("pla-ra" and "pla-chom") in Thailand. Lactobacillus cypricasei was isolated from Halloumi cheese, in
Cyprus.
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 alkaline phosphatase, alpha- and beta-glucosidase, fermentation of: arbutin, fructose, galactose, gentibiose,
glucose (without gas production), mannose, methyl alph-D-glucopyranoside, and turanose.

Negative results for arginine hydrolysis, catalase, esculin hydrolysis, esterase (C4), beta-galactosidase,
N-acetyl-beta-glucosaminidase, gelatin liquefaction, nitrate reduction, oxidase, starch hydrolysis, formation of slime from sucrose,
fermentation of: cellobiose, esculin, gluconate, melezitose, melibiose, raffinose, sorbitol and xylose.

Variable results for reaction in litmus milk, fermentation of: amygdalin, arabinose, glycerol, 2-ketogluconate, lactose (weak reaction),
maltose, mannitol, rhamnose, ribose, salicin (weak reaction), starch, sucrose, tagatose, and trehalose.
