Gram-negative rods. Motile by peritrichous fagella
After 48h on TSA, colonies are circular, matte, brittle and cream-coloured with slightly
undulate margins with an average diameter of 3mm, yellow pigmentation. Grows at
10 and 41 °C, with optimal growth observed between 30 and 35 °C. Grows at pH6-9
and inf 1-8% NaCl. Facultatively anaerobic.

Positive results for catalase, indole production, esculin hydrolysis, ONPG, nitrate
reduction, N-acetyl-beta-glucosaminidase, acid production from: dulcitol, malonate,
sorbitol and rhamnose.
Negative results for arginine dihydrolase, citrate utilization (Simmons), H2S
production, lysine decarboxylase, ornithine decarboxylase, gelatin hydrolysis,oxidase,
urease, Voges-Proskauer test, acid production from: D-adonitol, D-arabitol, 2-
ketogluconate, palatinose, D-raffinose, sucrose and tagatose.
Variable fermentation of 5-ketogluconate, D-lyxose, methyl-alpha-D-glucopyranoside
and D-trehalose.
Variable utilization of sucrose, D-salicin, 3-methyl glucose, D-serine, L-pyroglutamic
acid, citric acid, D-malic acid, tween 40, alpha-hydroxy-butyric acid, beta-hydroxy-D, L-
butyric acid and formic acid.
L. tamurae can be differentiated from L. adecarboxylata by utilization of citrate and
fermentation of adonitol and sorbitol.
