Protein secretion capacity of selected mutant strains: (A) β-glucosidase activity: fold increase in the relative fluorescence activity of the mutant strains secreting β-glucosidase in comparison to the reference strain JC0190. (B) Total protein: total protein content of the reference and mutant strains in the supernatants. The protein content of mutant 4 is around 4 μg and hence negligible in the graph. (C) α-Amylase secretion: fold increase in the α-amylase enzyme units of the strains SB024 and SB025 derived from mutants JCMT1 and JCMT8, respectively, compared to the reference strain SB023.
