[Influence modified and resistant potato starches on the E. coli culture].
Modified and resistant starches regulate the colon microbiota metabolism and gene expression. This adaptive response allows bacteria to obtain the new enzymes to metabolize the unusual substrates. The potato starches modify the colon residential microorganisms. It was a reason the study the influence of the modified and resistant potato starches on the E. coli lines defected in the gene reparation system. It allows us to estimate the participation of some components of gene reparation system in the adoptive response of bacteria to the chemical compounds. Potato starches in the concentration 1% have been found to be indifferent to the DNA E. coli lines Wp. RecA. PolA [Russian character: see text] UvrA. High amilose notato starch stimulates these lines growth that indicates to its prebiotic canacities.
