Prolonging the Viability of Lactobacillus plantarum through the Addition of Prebiotics into the Medium Clelia Altieri, Antonio Bevilacqua, and Milena Sinigaglia
Abstract: This article reports on the effects of prebiotics on the growth/death kinetics, metabolism, and biomass production by 2 strains of La robacillus plantaron (c19 and DSMZ 2601. isolated from table olives and purchased from a Public Collection. respectively). The research was divided into 3 different steps, in order to highlight the optimal rombinatuon for cell viability and experiments were performed under the conditions of an accelerated shelf life test: thus, 3 combinations were pointed out (fructooligosaccharides lPOSJ, 5 g/L: glucose inulin. 2.5 2.5 g/L: glucose FOS, 2.5 2.5 g/l). A sample containing only glucose was used as control. The results highlighted that the 3 combinations aforementioned prolonged cell viability over the time both under low and high inoculum conditions 3 and 9 lug CPU/mL. respectively): however, FOS a e caused a reduction of biomass production. even if cell number was not affected by this compound. Therefore, as a final result of this research. the combination glucose FOS could be proposed as a suitable mean to achieve an optimal production of biomass and prolong cell viability over the time. Keywords: biomass production. FOS, inulin. Lautoburillis plantarum, selection, viability Practical Application: Food producers require a prolonged viability of probiotic bacteria in functional foods: this goal is usually achieved by refrigeration. In this artic the prolongation of cell viability through the addition of prebiotics was proposed
