摘要：

The kinetics of enzymatic hydrolysis of rice bran oil in isooctane by immobilized Candida rugosa lipase in a batch reactor showed competitive inhibition by isooctane with a dissociation constant, K-I, of 0.92 M. Continuous hydrolysis of rice bran oil was performed in recycling, packed bed reactor with 4352 U of immobilized lipase; the optimum recycle ratio was 9 and the operational half-life was 360 h without isooctane but 288 h with 25% (v/v) isooctane in rice bran oil.
