Effect of μmax of Leuconostoc mesenteroides strains in simulated fermentations
Fermentations are biochemical processes in which bacteria transform substrates into products and metabolites of commercial value. Lactic acid bacteria (LAB) are microorganisms that produce lactic acid from fructose and glucose; however, when cultured in sucrose medium, the main product is dextran. T...

| Sumario: | Fermentations are biochemical processes in which bacteria transform substrates into products and metabolites of commercial value. Lactic acid bacteria (LAB) are microorganisms that produce lactic acid from fructose and glucose; however, when cultured in sucrose medium, the main product is dextran. This exopolysaccharide has important gelling, thickening, and rheological properties for the food and medical area. As in all fermentative processes, dextran production is affected by environmental conditions such as pH, temperature, and substrate, as well as the producing strain. Therefore, the aim of the work was to predict the effect of the μmax of thirteen Leuconostoc mesenteroides strains on their cell growth, substrate consumption, and dextran production in fermentative processes. The results showed that the simulation is a valuable tool to visualize kinetic behaviors and to be able to find and select the optimal parameters to execute real fermentations with successful results. |
