Exercise : Fermentation Reactors - Section 2
11.
The production of an amylase from starch by Aspergillus niger is often performed in a fed batch fermenter. This is due to the reason that
fed-batch reactor can be used to minimize starch concentrations and prevent a. niger from fermenting
fed-batch reactor can be used to minimize starch concentrations and thus reduce the viscosity of the medium
continuous reactor can be used to minimize starch concentrations and their inhibitory effects
all of the above

14.
Monoclonal antibodies are typically produced in fed batch reactors because
hybridoma cells ferment at high maltose concentrations
hybridoma cells yield higher lactate at high glucose concentrations
hybridoma cells respire at high glucose concentrations
