Comparativa entre modelos estocásticos de crecimiento bacteriano a distintas escalas

Abstract

En la industria alimentaria la calidad y la seguridad del alimento, así como los procesos implicados en su producción, envasado y transporte, se optimizan acudiendo a la microbiología predictiva. Esta disciplina modela el comportamiento de microorganismos, tales como bacterias, empleando modelos primarios para describir su crecimiento. Uno de los mayores retos en este contexto es modelar y simular el crecimiento cuando el número inicial de bacterias (inóculo) es reducido, ya que la población se comporta estocásticamente. Existen distintas alternativas de modelado, dependiendo de (1) el grado de detalle de la solución requerida, (2) los tiempos de cálculo y (3) la facilidad de calibración de sus parámetros. En este trabajo se comparan las soluciones y tiempos de cálculo, a la vez que se discute la identificabilidad estructural, cuando se aborda el problema desde una escala microscópica, con modelado basado en individuos, o desde una escala mesoscópica, mediante la derivación de la equivalente ecuación de Fokker–Planck modificada.
