Chlorella protothecoides microalgae are chosen for the present study because of having faster growth rate, high oil content, and high biomass productivity. Response surface methodology (RSM), as well as combined artificial neural network (ANN) with genetic algorithm (GA), are employed for the modelling of the reaction parameters and biodiesel yields. The input parameters were reaction time (40-120 min), temperature (45-65°C), methanol to oil molar ratio (6-10:1) (vol/vol), catalyst concentration (0.4-1.5 w/v), and biodiesel yield. An ANN model is developed, trained, and tested using experimental data from the combined RSM-based Box-Behnken design (BBD) technique. The optimised conditions the combined ANN-GA technique predicted were reaction time 105.6 min, reaction temperature 65°C, methanol to oil molar ratio 7.41:1 (vol. /vol.), and catalyst concentration 1.024 (w/v). Based on the results, combined ANN-GA techniques are recommended to be a quick and reliable approach for predicting reaction parameters for biodiesel production.
