The effect of different inducers on the cellulase and hemicellulase bioproduction by Aspergillus niger
NRRL-567 using apple pomace as a substrate was investigated. Rapid production of different cellulase
enzymes namely, FPase (filter paper cellulase), CMCase (carboxymethyl cellulase), BGL (-glucosidase),
and xylanase were observed with peak activity reaching between 48 and 72 h of fermentation period.
The higher FPase and BGL activities of 133.68
±
5.44 IU/gram dry substrate (gds) and 60.09
±
3.43 IU/gds,
respectively were observed while using CuSO4 and veratryl alcohol after 48 h of incubation time. The
higher CMCase activity of 172.31
±
14.21 IU/gds was obtained with lactose after 48 h of incubation period.
Similarly, higher xylanase activity of 1412.58
±
27.9 IU/gds was observed with veratryl alcohol after 72 h
of fermentation time. This study sheds light on the rapid bioproduction of fungal cellulase and hemicellulase
using low cost waste, apple pomace as substrate when supplemented with different inducers
