以脲酶和葡萄糖氧化酶为研究对象，首次利用活蚕液状丝素蛋白的构象变化即蛋白质的变性现象，将酶固定于蚕丝素蛋白中，提出了这种固定化方法的机理、性能以及用作电位法和电流法酶传感器响应特性的研究和实际应用的可能性。

Results showed that the activity of soil poly-phenol oxidases and acid phosphatase, and soil respiration were suppressed by Starane at 0.5 and 5 mgkg^(-1) dry soil, respectively, during the first several days of experiment, but were slight promoted thereafter. In contrast, treatment with Starane at 50 mgkg^(-1) stimulated at the beginning of experiment but inhibited following that time the activity of soil poly-phenol oxidases and acid phosphatase and soil respiration. Activity of urease was stimulated at the beginning but inhibited in the following days by Starane at 0.5 and 50 mgkg^(-1) dry soil, respectively. However, the pattern of stimulation of urease activity at first several days of experiment followed by reduction to the basil level was observed. With respect to invertase, its activity was constantly depressed in the presence of Starane.

结果表明使它隆在0.5mgkg^(-1)和5mgkg^(-1)质量分数时对土壤多酚氧化酶、酸性磷酸酶和呼吸强度的影响为轻微抑制－激活－恢复稳定的趋势，50mgkg^(-1)质量分数时为轻微激活－抑制－恢复稳定的趋势；使它隆在0.5mgkg^(-1)和50mgkg^(-1)质量分数时对土壤脲酶活性的影响为激活-恢复稳定的趋势，5mgkg^(-1)时则处于抑制－激活的趋势；各质量分数的使它隆浓度对土壤蔗糖酶和土壤全酚均为抑制作用，且质量分数越大抑制越强烈。
