Bifidobacterium reuteri Endo, Futagawa-Endo, Schumann, Pukall, Dicks, 2012.
Gram-positive irregular rods with rounded or tapered end, usually swollen and
branched, 03-1.0 / 1.5-6.0 µm, occurring singly or in pairs. Non-motile.
Colonies are beige, smooth, 1-2 mm in diameter after 2 days of anaerobic incubation
on MRS agar supplemented with 50 mg/l L-cysteine. Growth temperature 37 ºC. No
growth at 30 or 45 ºC. Grows at pH 5.0-7.0. Facultatively anaerobic.
Isolated from faeces of common marmoset, South Africa.
