The ability of survival of Pediococcus pentosaceus IDS885 strain in the gastrointestinal tract and the effect of ingestion of cultured vegetable drink prepared with 8 kinds of vegetables and Pc. pentosaceus IDS885 on fecal microflora in human were studied. Twelve healthy subjects administrated 100 g of cultured vegetable drink containing 5×108 CFU per gram for 4 weeks. Fresh fecal samples were collected before (day-5), during (day 3, 7, 14, 21, 28) and after ingestion (day 35). Pc. pentosaceus IDS885 was enumerated for all samples and the fecal microflora was analyzed before (day-5) and during ingestion (day 28). Pc. pentosaceus IDS885 strain was not detected before administration of cultured vegetable drink (day-5), but averaged 106∼107CFU per gram for ingestion period (day 3, 7, 14, 21, 28). When subjects stopped administration of cultured vegetable drink, Pc. pentosaceus IDS885 disappeared from all samples (day 35). In eight cases of 12 subjects, percentage of Bifidobacterium in microflora increased by ingestion of cultured vegetable drink. In five subjects whose percentage of Bifidobacterium was less than 15% increased from 10.2±1.5% to 21.7±12.8%, while percentage of Bacteroides decreased from 69.2±12.5% to 59.5±18.3%. From these results, we demonstrated that Pc. pentosaceus IDS885 strain can survive in the human gastrointestinal tract, and administration of cultured vegetable drink altered the composition of fecal microflora in a manner with a beneficial effect for human health.
