Gram-positive rods, 0.5 x 1.5-2.5 µm. Nonmotile.
Colonies on TPYG plates after 1 day at 37 ºC are opaque, convex, rough, small (less
than 1 mm), with irregular edges. Facultatively anaerobic. Grow at 10 and 15 ºC
(optimum temperature is 30-37 ºC); no growth at 42 and 45 ºC. Optimum pH 6.0-6.4.
Isolated from the faeces of a jaguar in Beijing Zoo.
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 arginine hydrolysis, esculin hydrolysis, fermentation of: arbutin, N-acetylglucosamine, cellobiose, fructose,
galactose, beta-gentiobiose, glucose (acid without gas production),  lactose, maltose, mannose, salicin, D-tagatose, and trehalose.

Negative results for catalase, fermentation of: adonitol, amygdalin, D- or L-arabinose, D-arabitol, dulcitol, erythritol, D- or L-fucose,  
gluconate, 2- or 5-ketogluconate, glycerol, glycogen, inositol, D-lyxose, mannitol, melibiose, melezitose, raffinose, rhamnose, ribose,
sorbitol, sorbose, starch, sucrose, D-turanose, xylitol, and xylose.
