Question

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

a.

fed-batch reactor can be used to minimize starch concentrations and prevent niger from fermenting

b.

fed-batch reactor can be used to minimize starch concentrations and thus reduce the viscosity of the medium

c.

continuous reactor can be used to minimize starch concentrations and their inhibitory effects

d.

all of the above

Answer: (b).fed-batch reactor can be used to minimize starch concentrations and thus reduce the viscosity of the medium
