| Abstract: |
Amorphothallus campanulatus tuber was
used as an efficient substrate for citric acid production by batch fermentation
using Aspergillus niger. The
amount of citric acid produced was compared with that produced from glucose as
substrate. To scale up the bioprocess, transition metal ions such as Cr, Mo, Cd
and Pb were added at optimum concentration as nutritional supplements and their
effect on the biosynthetic route of the citric acid cycle was observed.
Experimentally observed growth stages were used for mathematical modelling to
evaluate the kinetic parameters. The calculated values agreed well with the
observed ones.
