![عکس صفحه اول مقاله: Artificial neural network modeling and genetic algorithm based medium optimization for the improved production of marine biosurfactant Artificial neural network modeling and genetic algorithm based medium optimization for the improved production of marine biosurfactant](/preview/png/683061.png)
A nonlinear model describing the relationship between the biosurfactant concentration as a process output and the critical medium components as the independent variables was developed by artificial neural network modeling. The model was optimized for the maximum biosurfactant production by using genetic algorithm. Based on a single-factor-at-a-time optimization strategy, the critical medium components were found to be glucose, urea, SrCl2 and MgSO4. The experimental results obtained from a statistical experimental design were used for the modeling and optimization by linking an artificial neural network (ANN) model with genetic algorithm (GA) in MATLAB. Using the optimized concentration of critical elements, the biosurfactant yield showed close agreement with the model prediction. An enhancement in biosurfactant production by approximately 70% was achieved by this optimization procedure.
