An agitation-aeration system, shown in Figures 1b, 2b and 3b consisting of a mechanical agitator element, driven by an electric motor with input at the top or bottom of the bioreactor having in its interior a conduit for gases, with gas outlet through a) sintered metal cylinders for generation of microbubbles or b) a sintered metal plate at the bioreactor base or c) both systems (a) and (b ... Aeration-Agitation Bioreactor. This type of bioreactor (Fig. 3.3) is popular and is fundamentally the same as that used with microbial cultures. For small scale experiments, the aeration-agitation type bioreactors is widely used. However, when the culture volume is increased, many problems arise.

Agitators have been used in fermenters for many years. The functions of the mixer in fermentation processes requiring dispersion of air or oxygen in a broth are that they: Provide uniform dispersion... The efficiencies of the aeration and agitation were evaluated based on the volumetric mass transfer coefficient (K(L)a). The maximum SRP production of 11,580 EU/ml with a specific SRP productivity of 78.8 EU/g/h was obtained with an agitation of 400 rpm and aeration of 0.075 vvm, which was 58% higher than the shake-flask level.

Cells are very sensitive to changes in the culture environmental conditions, such as aeration, agitation, nutrients, and pH. This article discusses the importance of aeration and available options to control the oxygen mass transfer coefficient (kLa) within a bioreactor. Learn about Xcellerex single-use bioreactors that scale from 10 to 2000 L modular bioreactor components for gentle agitation, sufficient aeration and long-term perfusion were devel- oped and investigated with respect to their suitability from laboratory to production scale. Aeration systems have been designed for both shear sensitive cells and cells which tolerate bubbles.

A fermentor should be capable of being operated aseptically or should provide sterile conditions. The bioreactor provides adequate aeration and agitation for uniform mixing of the contents in the vessel. It should consume less power. A fermentor equipped with controlling probes that maintain the temperature, pH, oxygen level etc. For scaling up in fermentor or bioreactor you should calculate volumetric oxygen mass transfer coefficient kLa from shaker flask (KLa) and use this KLa to the fermenter.
