One unit was defined as the amount of enzyme that produces 1 nmol of reducing sugarper minute.
One unit was defined as the amount of enzyme that increases OD at 420 nm by 0.001 per minute at 40°C.
All values are mean±SD (n=3).
Different superscript letters (^a-c) in the same column indicate significant differences (p<0.05).
