were employed ranging from (50e75%) to the growth supported
substrate i.e., lemon peel waste. Lemon peel waste fermented
at 70% (w/w) moisture gave maximum production (pectin
lyase activity; 545 4.85 U/mL) after 4 days of inoculation with
A. oryzae however, an increase in moisture level from 70%
showed decreasing trend in the pectin lyase production
(Fig. 2).
