Assume that the empirical formula of a bacterial cell can be given by C5H7O2NP0.2. Further assume that for every gram of glucose fed, the resulting cell growth yield is 0.5 grams. a. What is the amount of ammonia (as nitrogen) needed to sustain 1 gram/L of cells in an engineered bioreactor b. What is the amount of phosphorus needed to sustain the same concentration of cells in the reactor?
