Chemostat with Cell Recycle- To keep the cell concentration higher than the normal steady-state level in a chemostat.- To increase the cell and growth-associated product yield.- For low-product-value processes: e.g. waste treatment.fuel ethanol,X1, Sv
Chemostat with Cell RecycleCell mass balance (qp=0, kd ≈0, X0=0, Monod equation is applied):A chemostat can be operated at dilution rates higher than the specific growth rate when cell recycle is used.where µ=µnet=µg-kd
