Abstract
Fermented milk prepared with Lactobacillus acidophilus SBT2062, Bifidobacterium longum SBT 2928, Streptococcus thermophilus SBT1035 and Lactobacillus delbrueckii subsp. bulgaricus SBT0164 was administered at 100 g/day for 2 weeks to 87 healthy adults (39 men and 48 women, average age 28.1 years). The fecal microflora of 14 adults (5 men and 9 women, average age 27.6 years) selected from the 87 healthy adults were studied. Improvement of fecal shape, change of fecal color from dark brown to yellowish brown, decrease of fecal odor and increase in defecation frequency of persons whose frequency was relatively low were observed after administration. The number and ratio of bifidobacteria to the total bacteria were significantly increased, whereas the number and ratio of Bacteroides to the total bacteria were significantly decreased after administration. Fecal ammonia content decreased although the fecal pH, p-cresol and indole contents did not change after administration.
