• Abstract:

  A simple mathematical model based on the experimental data was developed and the best values of kinetic parameters were determined for the enzymatic hydrolysis of the glucan fraction contained in the waste generated by the carrageenan processing of algal biomass (Kappaphycus alvarezii) aiming at the glucose accumulation. This residue was subjected to hydrolysis with several commercial enzymatic extracts containing different enzyme loads. A detailed sequence of model development, parameter estimation, and model validation is presented. The temporal profiles of glucose concentration were derived by direct analytical integration of the mathematical model, obtaining an explicit equation over time. The model adjustment goodness was evaluated by different statistical criteria, including the Fisher’s F-test, R2-value, and p-value and the accuracy of the model was judged acceptable. The good performance presented by the mathematical model recommends its use in further studies aimed at improving the enzymatic hydrolysis process.
