Abstract
The aim of this study was to develop a model that would be able to simulate the kinetics of cell growth, lactic acid production, pH drop and sugar consumption in algae-based fermentations with Lactobacillus acidophilus BUCSAV-375 strain. The kinetic parameters of the primary models for these dependent variables were expressed as a function of the initial dry matter concentration of the media, obtaining by treatment of biomass of microalgae of Spirulina platensis (Arthrospira platensis), and their buffering capacity. Later the parameters obtained from these models were used to establish mathematical relationships with the independent variables tested. The models were validated with 6 fermentations of L. acidophilus in different algae-based media. In most cases the proposed models adequately describe the biochemical changes taking place during fermentation and are a promising approach for the formulation of algae-based probiotic foods.
