Activating Compound Comment Organism Structure
additional information at fed-batch operation FBO1 (when air-flow rate decreases considerably), feed is given to the system in pulses in such a way that pretreated-beet molasses concentration increases by 10 kg/m3 (containing 2.5 g/L glucose and 2.5 g/L fructose), FBO2 (when fructose and glucose are completely utilized, pretreated-beet molasses is pulse-fed and its concentration increases by 10 g/L), and FBO3 conditions, almost the same BAL volumetric activities are obtained. Fed-batch operation FBO3 is the best feeding strategy because in FBO3 with the decreased amount of pretreated-beet molasses (6 g/L), shift response time from glucose to fructose consumption is avoided, and glucose and fructose consumptions are well correlated with air-flow rate, and the highest cell concentration (8.04 g/L) and BAL (2,315 U/mL) production are obtained (t=24 h) with the highest substrate yield on cell and product formation synthetic construct
