From: Enhancing the thermostability of α-L-rhamnosidase from Aspergillus terreus and the enzymatic conversion of rutin to isoquercitrin by adding sorbitol

Fig. 3

The intrinsic fluorescence spectra of α-L-rhamnosidase. a Without sorbitol before and after incubation at 70°C for 4 h. b Incubated at 70°C for 4 h with different concentrations of sorbitol in 10 mM phosphate buffer at pH 6.5. All spectra were corrected for the fluorescence of a protein-free sample. Each value represents the mean of three independent measurements
