Synonym:
Lactobacillus acidophilus group A4 of Johnson et al. (1980).
Gram-positive, short to long rods (0.5–1.5 x 1.5–10 μm) occurring singly, in pairs  and
in short chains. Nonspore-forming.
Colonies on BL (glucose-blood liver) agar plates are 0.5 to 2.0 mm in diameter,
circular to slightly irregular, entire, grayish brown to reddish brown, and rough.  
Facultatively anaerobic. Can grow at 15-45 ºC, and in 4% NaCl medium.
Isolated from chicken intestine.
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 fermentation of: amygdalin, cellobiose, esculin, fructose, galactose, glucose (without gas production),   maltose,
mannose, melibiose, raffinose, salicin & sucrose.

Negative results for catalase, fermentation of: arabinose, mannitol, melezitose, rhamnose, ribose, sorbitol, trehalose & xylose.

Variable fermentation of lactose & starch.
