| Resumo: | Lactobacillus reuteri is a heterofermentative species that lives in the gastrointestinal (GI), vaginal and oral tracts of humans and other warm-blooded animals. The action of probiotic L. reuteri is derived from its ability to exert an inhibitory effect on pathogens, combining several mechanisms, including the production of lactic acid, hydrogen peroxide and bacteriocin production. The reuterin is a neutral compound of low molecular weight, water soluble, active in a wide pH range, and resistant to proteolytic and lipolytic enzymes. This study evaluated the inhibitory effect of L. reuteri on pathogenic bacteria or food deterioration. L. reuteri showed ability to inhibit the growth of Aeromonas hydrophila, Bacillus cereus, Enterobacter aerogenes, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella tiphymurium, Staphylococcus aureus and Vibrio cholerae. It is suggested that the antibiotic produced by L. reuteri is the reuterin. |
