Abstract: A method of establishing direct feed microorganisms such as Lactobacillus reuteri in the gastrointestinal tract of avian organisms in which eggs are inoculated with living cells of the microorganism.
Abstract: The antibiotic .beta.-hydroxypropionaldehyde is obtained by cultivating strains of Lactobacillus reuteri under anaerobic conditions in the presence of glycerol or glyceraldehyde. This antibiotic has activity against Gram positive and Gram negative bacteria, against the yeast, Saccharomyces cerevisiae, and against the protozoan, Trypanosoma cruzi, and decreases ribonucleotide reductase activity.
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.
