Bifidobacterium minimum Biavati, Scardovi, Moore, 1982.
Oval, club-shaped or short rods, sometimes irregularly branched, 0.3-0.6 x 0.5-2.8
µm, ocurring in short chains and in clumps.
Colonies are smooth, convex, entire edges, gray, white or buff, shiny, 1 mm in
diameter. Dense turbidity with a flocculent sediment is produced in broth with
carbohydrates that are fermented; little or no growth is produced without a
fermentable carbohydrate. Anaerobic. Grows at 22-40 ºC.
Isolated from wastewater, sewage and cecum of pigs.
Undetermined.
