  • Method of determining the presence of an antibiotic produced by Lactobacillus reuteri
    Patent number: 5352586
    Abstract: The antibiotic reuterin is obtained by cultivating strains of Lactobacillus reuteri under controlled conditions. Reuterin has inhibitory activity against Gram positive and Gram negative bacteria, against yeast, Saccharomyces cerevisiae, and against the protozoan, Trypanosoma cruzi. Reuterin producing strains are identified by grown inhibition of susceptible microorganisms in the presence of glycerol or glyceraldehyde.
