Abstract

Neste trabalho, foi desenvolvido um modelo matemático que visa descrever as interações entre bactérias lácticas produtoras de bacteriocinas e a Listeria monocytogenes no alimento. As bactérias lácticas produzem bacteriocinas que preservam alimentos por meio de exclusão competitiva com outros microorganismos nocivos, como a Listeria. A análise estática e a dinâmica do modelo, representado por um sistema de equações diferenciais ordinárias, fornecem informações sobre o comportamento das soluções, e, também, permitem estudar a possível ação do ácido láctico e da bacteriocina, produzidos pela bactéria láctica, na redução e inibição de atividade de Listeria no alimento.
