Effect of Humidity and Fermentation Duration on Amylase Enzyme by Trichoderma harzianum

Abstract

The effects of humidity and duration of fermentation on amylase enzyme by Trichoderma harzianum were investigated in this work. Different Humidity were used as to test the best one to produce the amylase enzyme from this isolate. Also different duration of fermentation were test. Humidity increase from 15 to 20 and also won an award in both enzymatic activity and specific activity at humidity rises above 20. The best duration of fermentation was at 21 days.
