@article{(Open Science Index):https://publications.waset.org/pdf/9599, title = {Kinetic Study of Gluconic Acid Batch Fermentation by Aspergillus niger}, author = {Akbarningrum Fatmawati and Rudy Agustriyanto and Lindawati}, country = {}, institution = {}, abstract = {Gluconic acid is one of interesting chemical products in industries such as detergents, leather, photographic, textile, and especially in food and pharmaceutical industries. Fermentation is an advantageous process to produce gluconic acid. Mathematical modeling is important in the design and operation of fermentation process. In fact, kinetic data must be available for modeling. The kinetic parameters of gluconic acid production by Aspergillus niger in batch culture was studied in this research at initial substrate concentration of 150, 200 and 250 g/l. The kinetic models used were logistic equation for growth, Luedeking-Piret equation for gluconic acid formation, and Luedeking-Piret-like equation for glucose consumption. The Kinetic parameters in the model were obtained by minimizing non linear least squares curve fitting.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {3}, number = {9}, year = {2009}, pages = {471 - 475}, ee = {https://publications.waset.org/pdf/9599}, url = {https://publications.waset.org/vol/33}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 33, 2009}, }
