For this level of sophistication, a fermentation system needs to be used. The main differences are that (a) stirring is by a direct-drive mechanism with a motor, and (b) the vessel has a complex top that allows the inclusion of a range of sensors, probes, feed supply lines, and sampling devices for contamination-free monitoring and control. Fermenter kits (laboratory scale) are available in the range from lto 40 L and cost in the region of $450037,500 (E3,000-25,000) (with control of stirring speed, temperature, pH, and oxygen).
