Fig. 4From: Enhancing the thermostability of α-L-rhamnosidase from Aspergillus terreus and the enzymatic conversion of rutin to isoquercitrin by adding sorbitolFar-UV CD 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 signal generated by a protein-free sampleBack to article page
