Abstract
Fermented milk prepared withLactobacillus acidophilusSBT 2062, Bifidobacterium longumSBT 2928, Streptococcus thermophilusSBT 1035 andLactobacillus delbrueckiisubsp.bulgaricusSBT 0164 (containing 6.5×106∼1.0×107cfu/g ofL. acidophilusSBT 2062 and 6.0×106∼1.0×107cfu/g ofB. longum SBT 2928) was administered at 100 g/day for 1 week to 79 healthy adults (39 men, 40 women, average age 36.7 years). The fecal microflora of 9 adults (3 men, 6 women, average age 27.8 years) selected from the 79 healthy adults were studied. An increase in defecation frequency by the persons whose frequency was relatively low, improvement of fecal shape, change of fecal color from dark brown to yellowish brown, and decrease in fecal odor were observed after administration. The number and ratio of bifidobacteria to total bacteria were significantly increased, whereas the number of clostridia (lecithinase positive) and ratio of bacteroidaceae to total bacteria were decreased after administration. In addition, fecal pH decreased after administration.
