本文探究了将不同类型的表面活性剂和脂肪酶间的复配,通过测定其酶活,选择出对脂肪酶具有协同作用的表面活性剂.其中阴离子表面活性剂K12对脂肪酶DR表现出了抑制作用,相对酶活降低20%~30%,非离子型表面活性剂XL-90、AEO9和TX-7对脂肪酶有明显的激活作用,其中TX-7可使相对酶活提高到150%.接着进一步考察其在兔皮脱脂中的应用效果,添加非离子表面活性剂的脱脂率增大,TX-7和AEO9尤为明显,脱脂率分别达到80.63%和76.45%,比DR脂肪酶单独脱脂提高了23.19%和16.80%.%In this paper, the effects of the compound consisted of different surfactants and lipases were investigated. The surfactants which had synergistic effects on lipase DR were confirmed on basis of the enzyme activity. The anionic surfactant K12 showed inhibitory effect,relative enzyme activity reduced 20%~30%, and the nonionic surfactants XL-90, AEO9 and TX-7 had obvious activating effect, relative enzyme activity increased to 150% by addition of TX-7. Then the degreasing effects of the compounds were studied in the degreasing of rabbit skin. The degreasing rate was markedly increased by addition of the nonionic surfactant, in which the degreasing rate were 80.63% and 76.45%respectively by adding TX-7 and AEO9, increased 23.19%and 16.80% respectively compared with the control.
