Fig. 3From: Innovative approach for semi‐continuous production of puerarin palmitate via transesterification with novel immobilized lipaseSolvent stability of the three lipases in tert‐amyl alcohol after incubation for 72 h. Reaction conditions: 10 mM p‐NPP solution and lipase solution in 50 mM Tris‐HCl buffer (pH 8.0) in a 1:1 (v/v) ratio, reaction temperature of 40 ℃, and reaction time of 20 min. Different letters above the bars indicate significant differences between lipases according to Tukey’s HSD test (P < 0.05)Back to article page
