Popis: Bifidobacteria represent the largest group of human intestinal bacteria. They have an important place in human health and represent the dominant group microflora of the newborn breast-fed. Following the behavior of strains of Bifidobacteria isolated from the breast-fed infants and from saline rehydration solution was considered in order to develop therapeutic fermented milk. Samples from newborn infants aged 10 months, or from a saline rehydration solution (Celia/Develop ORS) containing Bifidobacteria sold was used and isolated strains belonged to breve and longum species. Those strains showed preferences to neutral pH. They are mesophilic and tolerate high temperatures (42 °C). Glucose was commonly carbohydrate used in selective media for Bifidobacteria. Production of titratable acidity and therefore lowering the pH varies from one strain to another.
