对超滤法浓缩提取萝卜ＰＯＤ（ｐｅｒｏｘｉｄａｓｅ）过程中酶活、比活力、蛋白质浓度及浓缩液体积等的动态变化的初步研究表明：（１）时间与浓缩液的蛋白质浓度、酶活、酶损失率间，浓缩液体积与蛋白质浓度、酶活、比活力及酶活的增加倍数间，以及体积浓缩倍数与酶和蛋白质的得率间的关系，均可用方程ｙ＝ａｅｂｘ来表示；（２）时间与透过液的蛋白质浓度及酶活间的关系可用方程ｙ＝ａ＋ｂ１ｘ＋ｂ２ｘ２＋ｂ３ｘ３＋ｂｘ４４来表示；（３）浓缩液蛋白质浓度与酶活及酶的浓缩倍数间，时间与浓缩液体积及透过液的比活力间的关系，均可用方程ｙ＝ａ＋ｂｘ来表示．
The preliminary studies on the dynamic changes of enzyme activity, specific activity, protein concentration and volume of concentrate during the process of concentrating and extracting peroxidase by ultrafiltration showed that: (1) the protein concentration, enzyme activity, enzyme loss The relationship between volume, protein concentration, enzyme activity, specific activity and enzyme activity, as well as the relationship between volume concentration ratio and enzyme yield and protein yield can be expressed by the equation y = aebx. (2) The relationship between the time and the protein concentration and the enzyme activity of the transdermal fluid can be expressed by the equation y = a + b1x + b2x2 + b3x3 + bx44; (3) The ratio of the protein concentration in the concentrate to the enzyme fold- The relationship between vitality, can be used to represent the equation y = a + bx.
