Biocontrol of Listeria monocytogenes by lactic acid bacteria isolated from brewer's grains used as feedstuff in Argentina

摘要: Abstract Brewer's grains are the most important by-product of brewery industry and it is mostly used as a protein energy source in animal nutrition. Listeria monocytogenes food-borne pathogen can cause invasive diseases such meningoencephalitis, sepsis, abortion, gastroenteritis humans several species. The aim this work was to study antilisterial activity lactic acid bacteria (LAB) isolated from brewer's grains. incidence spp. 3.12%. Twenty-one LAB inhibited growth eight strains L. monocytogenes. mean inhibition halo cell free supernatants ranged between 11.5 24.5 mm. isolation with promising based on their capacity produce antimicrobial compounds. production metabolites by substrate would generate an unfavorable environment for pathogenic bacterium under study.
