Effect of temperature on activity and stability of Aspergillus sp. DHE7 β-glucosidase: a Effect of temperature was determined by assaying the enzyme at different temperatures ranging from 25 to 90 °C, at pH 5.0 (0.05 M Na-citrate) against p-NPG as substrate. b Thermal stability behavior of Aspergillus sp. DHE7 β-glucosidase was evaluated by pre-incubating of the purified enzyme at different temperatures (pH 6.0, 30–90 °C) in the absence of substrate and assayed for residual activity on p-NPG under standard assay conditions
