Lactic acid production from lactose by Lactiplantibacillus plantarum AC 11S was studied. The influence of initial substrate concentration investigated, and optimal pH temperature were determined. An unstructured mathematical model developed comprising equations for bacterial growth, consumption, product formation. solved with different terms specific growth rates considering and/or inhibition. best lactic achieved at = 6.5 30 oC. Production mainly growth-associated over 15 g/L a considerable inhibition observed. parameters models determined compared. While the modified Gompertz equation gave fit biomass variant logistic including term described in way entire set formation concentrations.
