The analysis of results prebiotic activity natural sugarsubstitute, received with application of immobilization bacteria cells Erwinia rhapontici is conducted. On the basis of developed before biotechnology it is received isomaltulose is natural sugarsubstitute and are investigated it prebiotic properties in vitro conditions. Dynamics of growth of Bifidobacterium bifidum on medium with various sources of carbon is studied, for example isomaltulose, inulin, lactose, tregalose, fructose. Calculation of cages bifidobacteria on different medium on fixed dabs is spent and intensity of bifidocultures metabolic processes is investigated. Results of research of symbiotic relations of representative useful microflora in intestines – B. bifidum with an is conditionalpathogenic microorganism – Escherichia coli are analysed. On the basis of researches results it is proved isomaltulose prebiotic activity in vitro conditions.
