Bioreactors Types: 6 Types of Bioreactors used in ...

A pressure-cycle fermenter with large dimensions constitutes a tower bioreactor (Fig. 19.2B). A high hydrostatic pressure generated at the bottom of the reactor increases the solubility of O 2 in the medium. At the top of the riser, (with expanded top) reduces pressure and facilitates expulsion of CO 2.The medium flows back in the down comer and completes the cycle.

Production of recombinant protein in Pichia pastoris by ...

P. pastoris has the capacity to produce large quantities of protein with eukaryotic processing. Expression is controlled by a methanol-inducible promoter, which allows a biomass-generation phase before protein production is initiated. The target protein is secreted directly into a protein-free mineral salt medium, and is relatively easy to purify.

Bioreactors can be costly to construct since generally the systems are lined and often contain additional components, such as settling ponds and/or aerobic polishing cells. The West Fork system, which contained two parallel bioreactors and an aerobic polishing cell, cost about $700,000 to construct in 1996 (Gusek et al. 1998).
