Bioreactors- Introduction
Importance of considering process engineering factors
when culturing cells.
Biological factors include the characteristics of the
cells, their maximum specific growth rate, yield
coefficient, pH range and temperature range.
The productivity of a fermentation is determined by
the mode of operation of the fermentation process; eg.
the advantages of fed-batch and continuous
fermentations over batch fermentations.

The oxygen demand of an industrial process is
generally satisfied by aeration and agitation
Productivity is limited by oxygen availability and
therefore it is important to the factors that affect a
fermenters efficiency in supplying O2
O2 requirement, quantification of O2 transfer and
factors influencing the transfer of O2 into solution
