description: DESCRIPTION OF LIMOSILACTOBACILLUS FASTIDIOSUS SP. NOV.   
 Limosilactobacillus fastidiosus (fas.ti.di.o′ sus. L. masc. adj. fastidious, fastidious, referring to the fastidious growth requirements of the type strain).   
 Cells are Gram-positive, non-motile, non-spore-forming, catalase-negative and heterofermentative. Cells are rodshaped, measuring 0.9–3.0×0.6–0.9 µm. Colonies of the type strain WF-MO7-1 T on MRS agar plate incubated at the anaerobic condition at 37 °C for 2 days are whitish, opaque, raised, circular and entire, with a diameter of 1.2–2.2 mm; no colony appears on MRS agar plate incubated at the aerobic condition at 37 °C for 2 days. D-Lactate,L-lactate and gas are produced from glucose fermentation by the type strain WF-MO7-1 T. No growth occurs in 96-well microplate at 15, 30, 37 or 45 °C; in Falcon 15 ml tubes, cell growth occurs at 30, 37 and 45 °C (optimum) but not at 15° C. Growth occurs at pH 4.5–7.5 in MRS broth. The most abundant fatty acids of WF-MO7-1 T are C 16:0, summed feature 7 (combination of C 19:1 ω 6 c and/ or C 19:0 cyclo ω 10 c) and C 18:1 ω 9 c. Acid is produced from L-arabinose and aesculin; acid production from D-galactose, D-glucose,D-fructose, maltose, lactose, melibiose and raffinose is strain-specific; acid is not produced from D-ribose, D-xylose,D-mannose, methylα- D-glucopyranoside, sucrose, potassium gluconate, glycerol, erythritol, D-arabinose, L-xylose,D-adonitol, methyl β -D-xylopyranoside,L-sorbose, L-rhamnose, dulcitol, inositol, D-mannitol,D-sorbitol, methyl α- D-mannopyranoside, N -acetylglucosamine, amygdalin, arbutin, salicin, cellobiose, trehalose, inulin, melezitose, starch, glycogen, xylitol, gentiobiose, turanose, D-lyxose, D-tagatose,D-fucose,L-fucose,D-arabitol,L-arabitol, potassium 2-ketogluconate or potassium 5-ketogluconate. The cellwall peptidoglycan of WF-MO7-1 T contains the amino acids alanine (Ala), glutamic acid (Glu), aspartic acid (Asp) and ornithine (Orn), with the molar ratio 1.5 (Ala):0.9 (Asp):1.0 (Glu):1.1 (Orn), suggesting the cell-wall peptidoglycan type A4α L-Orn–D-Asp by [38]. The DNA G+C content of WF-MO7-1 T is 39.1mol%.   
 The type strain is WF-MO7-1 T (=DSM 110576 T =LMG 31630 T), which was isolated from the jejunum of root vole (Microtus oeconomus) caught in the Vilnius area in Lithuania [13].
