Biological activity of BGL@MOFs and free BGL. The BGL@UiO-66-NH2, BGL@ZIF-8, and free BGL at neutral conditions, acidic conditions, and acidic conditions with protease treatment. For the protease treatment, BGL@MOF samples were incubated with protease under acidic conditions for 2 h at 37 °C and then activity was characterized by assaying at the same temperature. The decomposition of ZIF-8 composites was observed at pH levels below 6.0. Error bars are standard deviations (n = 3), except for BGL@ZIF-8 at pH = 6.0 (n = 2).
