What will be the doubling time and the division rate of the cells in the CSTF? =0.7950 h; =1.2595 h – 1 b. What will be the cell and substrate concentrations of the outlet stream? C S =2.1148 g/L; C X =4.7311 g/L c. If you connect one more 10-L CSTF to the first one, what will be the cell and substrate concentration in the second fermenter?
WebNational Center for Biotechnology Information WebProblem 6.13 A strain of yeast is being cultivated in a 30—L CSTF with a cell recycling system (cell settler) as shown in the following figure. The cell settler was designed so hat the cell concentration of its outlet stream is 30 percent of that of its inlet stream, whereas the substrate concentrations of the two streams are the same.
WebDec 15, 2016 · The heat-resistant bacterial spores in themedium can be characterized by an Arrhenius coefficient (kd0) of 5.7×1039hr–1 and an activation energy (Ed) of 2.834×105 kJ/kmol (Deindoerfer andHumphrey, 1959). The sterilizer will be constructed with the pipe with aninner diameter of 0.102 m. Steam at 600 kPa (gage pressure) is available tobring ...

WebThe most productive fermenter system is a CSTF operated at the cell concentration as which value 1/rX is minimum because it requires the smallest residence time. 2. If the final cell concentration to be reached is in the stationary phase, the batch fermenter is a better choice than the CSTF because the residence time required for the batch is ...
