Protease activity with and without inhibitor in Aspergilli using WB and SBP as carbon sources. A: Overall protease activity in Aspergilli growing on WB and SBP. Seven Aspergilllus species were grown on WB or SBP on 30°C and sampled at 72 h, protease activities were measured for each sample in 2 biological replications with technical triplicates. B: Protease activity inhibition in Aspergilli. With the same settings described for Figure 1A, the protease activity was measured after adding corresponding inhibitors. The ratio of dropped activity was calculated by PercentageDroppedActivity = [1- (activity after adding inhibitor/original activity without inhibitor)]%. This dropped activity indirectly represents the proportion of corresponding protease activity in the supernatants, higher this number, bigger proportion of such type of protease takes the overall activity. Legends: WB and SBP: protease activity in wheat bran and sugar beet pulp, respectively.
