The results of assessing the survival rate of probiotic microorganisms on media containing sodium glutamate, tartrazine and sodium benzoate in the concentration range of 10–4 –10–7 M in vitro are presented. It is shown that the effect of glutamate, sodium benzoate and tartrazine on different strains manifests itself both in a sharp inhibition of the viability of cultures and a stimulation of their growth. In the Lactobacillus acidophilus with tartrazine of 10–4 M and 10–5 M, the survival rate of the strain ranged from 10.5 to 45.62% as compared to the control. The survival rate of the Enterococcus faecium SF 68 strain with nutritional supplements of 10–5 M and 10–6 M was 15.29 and 35.6%, respectively, and Escherichia coli M 17 strain ranged from 49.1 to 58.29% as compared to the control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
