Isolation and molecular Identification of lactic acid bacteria from infant's feces as ideal probiotics for therapeutic uses
Probiotic / lactic acidbacteria
Probiotic bacteria, such as LAB, are active bacterial cultures with unique characteristics that allow them survive in the gastro-intestinal tract (GIT) and overall health. This study was concluded in two parts: The first part was designed to isolate novel lactic acid bacteria from the Egyptian infant feces, in vitro, screen the immunomodulatory properties of the isolated LAB, characterize the probiotic properties of the selected isolates and identify the selected isolates on their molecular basis. The second part was to evaluate the use of the new probiotic bacteria strains in making functional bioyogurt. The results revealed the possibility of using new isolates mixed with yogurt starter to produce bioyogurt with good organoleptic, chemical, rheological and microbiological properties and prolonging the shelf life during cold storageup to 21 days. The final viable cell counts of these strains were within the levels needed (106-107 cfu g-1) for achieving the probiotic bacterial delivery system (enhance their health benefits).
