Fermentor design
| Dialysis Fermentor Systems for Concentrated Culture of Microorganisms by Gallup and Gerhardt (1963) describes a fermentor connected to a dialysis unit that allowed extremely high cell density and other favorable features. The semipermeable membrane was made of regenerated cellulose and held taut in a frame in a separate chamber.. Feeding could be conducted by exchange at the membrane. Extremely high cell density was achieved with the Serratia marcescens culture. When a reservoir chamber was used to with dialysis tubing a second phase to the growth phase was introduced. Addition of polyethylene glycol can drive the water from a culture and cause them to flocculate (and can clog a machine).
