WebSummary. As for any reactor operation, the primary purpose of fed-batch operation is to maximize the rates of cell growth and product formation so that the total rate of product formation (productivity) or product yield (selectivity) is maximized. The desired product may be classified into (1) high volume–high margin products, (2) high volume ... WebThis study was undertaken for further enhancement of phytase production with Aspergillus ficuum in bench-top bioreactors by conducting fed-batch fermentations. The results showed that addition of 60 g of glucose and 10 g of Na-phytate at 96 h of fermentation increased phytase activity to 3.84 and 4.82 U/ml, respectively. everlast construction
