Optimization of Growth and Amylase Production by Aspergillus flavus
Grown on Some Agricultural Raw Materials in Nigeria
Abstract:
Aspergillus flavus exhibited high growth and amylase
production. Various Polysaccharides, including soluble starch, sorghum, cassava
peel and maize induces high amylase production with maximal amylase activity
at 2% W/V. An initial linear increase in amylase activity with increase in substrate
concentration was obtained up to 2% W/V. An antagonistic relationship was obtained
between amylase activity and substrate concentrations higher than 2% W/V, in
the culture filtrate of Aspergillus flavus grown in shake flasks. The
maximum growth and amylase production was obtained on the sixth day of incubation
at a pH of 7.0 temperature of 29±1°C and 80 rpm. It is concluded
from this study that cassava peel as well as sorghum may be an alternative carbon
substrate for large scale cultivation of A. flavus for amylase production.
