Example: Consider cell as a reactor. The nutrient corn steep liquor enters the cell of the
microorganism Penicillium chrysogenum and is decomposed to form such products as
amino acids, RNA and DNA. Write an unsteady mass balance on (a) the corn steep liquor,
(b) RNA, and (c) pencillin. Assume the cell is well mixed and that RNA remains inside the
cell.
In Out
Corn Steep Liquor Penicillin
Penicillium chrysogenum
Assumption:
Penicillin is produced in the stationary state.
→ no cell growth & nutrients are used in making the product.
