Key: + = acid produced 24-48 h (9096 or more strains)
- = no acid produced 21 days (9076 or more strains)
d = some strains positive, some negative
(+) = acid produced slowly (3-7 days)
(d) = some strains produce acid slowly (3-7 days), other strains nagative
.f. All species produce acid but no gas in 24-48 h from amygdalin, aesculin, cellobiose, dextrin, fructosc, glucose, maltcse,
No acid in 21 days from adonitol, dulcitol, erythritol, inositol, inulin or raffinose.
$ This species is very likely not a member of the genus Listeria.
