- For the production of a secondary metabolic by Streptomyces coelicolor, a fed batch was performed. At the end of the single batch phase, the following conditions were reached in the reactor: V=10000L, cell concentration X=10g/L and product concentration P=0.1g/L. The feeding was then started with constant flow F= 200L/h, for 100h. Knowing that the substrate concentration in the feeding medium was SF= 80g/L and in the fermentation medium it was practically null, calculate: a) The final concentration of cells and productb) If the reactor were fed with a constant dilution rate (D), what should be the value of D used to reach the same cell concentration obtained in the situation with constant flow?μp= 0.01 g of product/ (g of cells.h)Y x/s = 0.15g cells/g of substrateDifferentiate between a yeast-lactic and a mold-lactic fermentationThe dichotomous key below can be used to distinguish between the three bacteria used for the fermentation experimentUse the to identify which of the three bacteria are indicated by A, B and in the key?
