SELECTION OF THE PROBIOTIC STRAINS OF LACTIC ACID BACTERIA STIMULATED BY FRUCTANS IN THE PRESENCE OF CALCIUM

The effect of fructooligosaccharides (FOS, WAKO, Japan) and fructan mix (Raftilose Synergy 1, Orafti, Belgium) on the growth and acidifying activity of Lactobacillus (7 strains) and Bifidobacterium (13 strains) in the presence of calcium lactate or carbonate (8 g/L) was studied in comparison to the control which did not contain calcium. The calcium compounds supplemented to the media containing FOS or Raftilose Synergy 1 did not affect the growth of Lactobacillus, though, in the presence of Raftilose Synergy 1, the growth of strains was weaker in comparison to the FOS. The pH level in Lactobacillus cultures containing FOS and calcium compounds, especially calcium carbonate, was higher than in the control. Growth and acidifying activity of Bifidobacterium strains in the media containing FOS or Raftilose Synergy 1 and calcium compounds were comparable to the control. The studies allowed the development of synbiotics for the improvement of calcium bioavailability from diet supplemented with the mineral nutrient.
