| Summary: | This work aims at optimizing the media constituents for citric acid production from oil palm empty
fruit bunches (EFB) as renewable resource using artifiial neural networks (ANN) approach. The bioconversion
process was done through solid state bioconversion using Aspergillus niger. ANN model was built using
MATLAB software. A dataset consists of 20 runs from our previous work was used to develop ANN. The
predictive and generalization ability of ANN and the results of RSM were compared. The determination
coeffiients (R2-value) for ANN and RSM models were 0.997 and 0.985, respectively, indicating the superiority
of ANN in capturing the non-linear behavior of the system. Validation process was done and the maximum citric
acid production (147.74 g/kg-EFB) was achieved using the optimal solution from ANN which consists of 6.1%
sucrose, 9.2% mineral solution and 15.0% inoculum. |
