Lactobacillus composti  Endo and Okada 2007.

Homotypic synonym:
Agrilactobacillus composti (Endo and Okada 2007) Zheng et al. 2020.
Gram-positive rods (0.8 × 2.0–60 μm), occuring singly or in pairs and chains.
Colonies on MRS agar are beige, smooth and approximately 1 mm in diameter after
incubation for 2 days at 30 ºC. Facultatively anaerobic. Grow at 15 and 37 ºC, but not at
45 ºC. Weak growth at 10 ºC. No growth in 5% NaCl medium. PH range 3.5-4 to 8.5-9.
Isolated from a compost of distilled "shochu" residue, Japan.
Undetermined.

Facultatively heterofermentative. DL-Lactic acid is a major end-product from D-glucose;
D- and L-lactic acid are produced in the ratio 1 : 1.

Positive results for fermentation of: arabinose, fructose, galactose, glucose acid (without gas production), gluconate (weak reaction),
maltose, mannitol, mannose, melezitose, melibiose, rhamnose (weak), salicin (weak), sorbitol, sucrose, trehalose, and xylose.

Negative results for catalase, nitrate reduction, fermentation of: cellobiose, inulin, lactose, raffinose, ribose, and starch.
