In a single stage continuous extraction system. solvent is added to cell-free culture filtrate containing the product. If the partition coefficient of the product is 5. then to extract 90% of the product, assuming ideal single stage, the flow rate of solvent should be times the flow rate of the culture filtrate.

A batch reactor produces 25g/L of product. The fermentation time is 4 days and 1 day extra is required as downtime for cleaning, sterilization and setting up the reactor. If total number of working days is taken at 300 days/year. Then to produce 1 ton/year of product the reactor size has to be approximately
