Obtención de biopelículas binarias activas y su efecto en la vida útil microbiológica del camarón blanco (Penaeus vannamei)

Abstract

In this research active biofilms based on alginate, cornstarch and water extract of lemon balm (Melissa officinalis L) were developed, assessing their impact on the microbiological shelf life of Pacific white shrimp (Penaeus vannamei). Microbial growth kinetics using as indicators microorganism aerobic mesophilic bacterial modeled mathematically through Baranyi y Robert equation by the program DMFIT were used for determinate the microbial growth parameters at different temperatures. Finally Hinshelwood - Monod equation was used to estimate the shelf life of the shrimp. The results indicated that is possible obtain binary biofilms containing aqueous extract of lemon balm for the shrimp conservation, because increments of 6 days were obtained in the shelf life of shrimp coated with biofilms.
