(1)PAL is better entrapped by PAG with a T∶C ratio of 8∶30.(2)PAL immobilized by glutaric dialdehyde on Bio-Gel P-300 is better than by CDC.(3)The best one is the dehydration and redehydration method.(4)Immobilized and permeated PAL active yeast cells are resistant to trypsin digestion and retain its PAL activity.

(1)固定化酶活性采用T∶C比为8∶30明显高于8∶19；(2)以戊二醛将PAL固定于Bio-GelP300优于用DCD固定化的酶；(3)质脂体包被中以脱水再加水法对酶活性影响较少，脂类组成以磷脂酰胆碱：胆固醇：磷脂酰丝氨酸比值7∶2∶1最好；(4)固定化PAL活性酵母细胞能较好地抵抗人工肠液中胰蛋白酶的水解作用，亦能明显降低苯丙氨酸的浓度。
