EVALUATION OF THE PERFORMANCE OF PLANTAGO PSYLLIUM, PLANTAGO MAJOR AND LALLEMANTIA IBRICA LOCAL PREBIOTICS ON LACTIC ACID BACTERIA

Background and Aim:Prebiotics are resistant to inappropriate conditions of the stomach and are often as nondigestible dietary ingredients that beneficially affect the host by selectively stimulating the growth and or activity of one of a limited number of bacteria in the colon, thus improve host health. In recent years, a new strategy has been developed using the combination of probiotics with prebiotics, called synbiotics. Synbiotic function is more effective than probiotic and prebiotic function alone in improving the quality of life in patients with ulcerative colitis, in preventing colorectal cancer or in microbiota positive regulation. In this research the effect of local prebiotics on lactobacillus bacteria to achieve new synbiotic formulation has been investigated.Methods:Three samples of prebiotic including Plantago psyllium, Plantago major and Lallemantia ibrica were selected and their effects on 4 Lactobacillus strains including UT1, ST1, CT2 and JTa1, as well as some antimicrobial testing clinical strains were investigated by standard agar well-diffusion method.Results:The results showed that all three prebiotics were studied not effective against lactic acid bacteria while they showed antimicrobial effects on gram positive and gram negative clinical strains.Conclusion:The results of this study indicate that the prebiotic compounds studied are usable with lactobacilli with the aim of providing effective synbiotics.
