Abstract
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.
