Stability of Surfactant—coated Candida Rugosa Lipase in Isooctane
摘要
The stability of Candida rugosa lipase coated with glutamic acid didodecyl ester ribitol amide was investigated taking esterification of lauryl alcohol and lauric acid in isooctane as a model reaction.At 30℃,the half-life of the activity of the coated lipase was ca 10h,the enzyme activity became less changed after 12h and the residual activity was 39% of the initial value ,The coated lipase obeyed a first-order deactivation model with a deactivation energy of 29.9 J.mol^-1.
