Figure 5.1 Classification of two-liquid
phase biocatalytic processes based on
the solubility of both the substrate (S)
and product (P) molecules. The
biocatalyst may be a whole-cell or an
immobilised enzyme and is assumed to
be present in the aqueous phase.
Dashed lines represent mass transfer
processes.
critical level and maximum use is made of the available activity. Reactor designs and
operating conditions to allow us to achieve these criteria will be discussed later.
Multiphasic systems thus allow high overall concentrations of all substrates in the
reactor, regardless of preferential solubility, while concentrations local to the biocatalyst
