Production of exopolysaccharides by Lactobacillus and Bifidobacterium strains of human origin, and metabolic activity of the producing bacteria in milk

The pH values of milks fermented with exopolysaccharide (EPS)-producing Bifidobacterium and Lactobacillus strains of human origin and increase in log colony-forming units per gram after incubation at 37°C for 17±1h. The strain Streptococcus thermophilus ST-body-1, which is used in yogurt manufacture, was used as an EPS-producing strain control.

Mean values (mM) for lactose consumption and production of lactic acid and acetic acid in milks fermented with exopolysaccharide (EPS)-producing Bifidobacterium and Lactobacillus strains of human origin at 37°C for 17±1h. The strain Streptococcus thermophilus ST-body-1, which is used in yogurt manufacture, was used as an EPS-producing strain control.
