Comparison of batch, fed-batch and continuous well-mixed reactors for enzymatic hydrolysis of orange peel wastes
No full textAn alternative potential feedstock for bioethanol in the automotive sector is citrus peel waste (CPW), which can be processed through enzymatic hydrolysis and fermentation. The present work considers mathematical modeling of orange peel wastes (OPW) hydrolysis with the use of free enzymes and compares the performance of batch, fed-batch and continuous well-mixed reactors after introducing appropriate rate equations in dynamic mass balances. MATLAB® was used for model implementation.
Following the Michaelis–Menten approach, the authors used their own kinetic parameters for the pectin hydrolysis rate equation. The parameters were generated in an apposite experimental program for OPW hydrolysis to galacturonic acid with consideration of product inhibition; the corresponding values were obtained after Lineweaver–Burk linearization and are: rmax = 0.28 g/(L min), Km = 19.80 g/L and KIGA = 6.96 g/L, respectively. Vice-versa, the authors adopted the Kadam's group kinetic schemes and parameters for cellulose hydrolysis to cellobiose and glucose. The mathematical model of a well-mixed batch reactor was perfectly validated against the experimental results of OPW hydrolysis to galacturonic acid. In the case of a continuous well-mixed reactor, high dilution rates determine low conversion of OPW. The increased complication of fed-batch operation does not add advantages when compared to batch processing
Enzymatic hydrolysis of commercial citrus pectin and orange peels by Pectinex Ultra SP-L: best parameter fitting and comparison of results
No full textThis work is aimed at determining and comparing the best-fitted kinetic parameters in enzymatic conversion rate of commercial-grade and orange waste (OPW) pectin to galacturonic acid. The Michaelis-Menten approach was adopted. After implementing a suitable experimental plan, the elaboration of the results provided the kinetic parameters by means of the three classical linearization methods, i.e., Lineweaver-Burk, Langmuir and Eadie-Hofstee. However, the best fitting was given by a Matlab-based, non-linear regression method employing the Gauss-Newton algorithm. The product inhibition mechanism proved to be of the competitive type. The kinetic parameters are rmax=1.10 g/(L min), Km=10.42 g/L and KIGA=10.05 g/L for commercial pectin; rmax=0.28 g/(L min), Km=19.28 g/L and KIGA=6.96 g/L for OPW. Accordingly, the hydrolysis rate of the OPW is slower than commercial pectin, but still acceptably fast and convenient
