[The bacterial QS-systems and prospects of creation of new metabolic probiotic preparations]
Abstract:
Biological functions of exometabolits of various bacterial species were analyzed from Quorum Sensing position, which showed that the functional activity of microbiocenosis is in many respects determined by the system of metabolic regulation. Possibility of changing the composition of complex microbial communities with low-molecular compounds, products of bacterial cell vital activity, is grounded from theoretical point of view. The authors adduce data on the effects of a synthetic composition on the basis of E. coli metabolites, an ingredient of colibacterin, a probiotic preparation. The preparation demonstrated a high stimulating activity towards a range of microorganisms of normal microflora, and an ability to improve the condition of intestinal epitelial cells. The results may substantiate application of metabolic probiotics for correction of intestinal microflora in man.
