本研究以表面經過不同矽烷類修飾之中孔徑分子篩為擔體,利用物理吸附或化學鍵結方法製備固定化Lipase MY。其次藉由測試固定化酵素之比反應性、鏡像選擇性、最佳反應溫度、長時間下的穩定性及耐溶劑性篩選最佳固定化方法。結果發現以環氧修飾的中孔徑分子篩得到之固定化酵素具有高鏡像選擇性、最佳反應溫度可提高10 ℃以及長時間處於60 ℃下穩定性仍表現不錯等優點。
以固定化酵素進行外消旋Naproxen三氟乙酯之水解動力分割時,利用Michaelis-Menten反應機構、產物抑制作用及酵素失活之動力模式,可以成功獲得與實驗值相當一致的結果。此外,並發現添加三辛基胺可有效減少酸抑制作用以及達到增加酵素反應性之效果。
Lipase MY have been immobilized on the surface of mesoporous molecular sieve that was functionalized with different organalkoxysilanes by using physical adsorption or chemical binding method. Then, the best immobilization method was selected by comparing the specific activity, enantioselectivity, the optimal reaction temperature, stability with time and solvent for various immobilized enzyme. Lipase MY immobilized onto the mesoporous molecular sieve modified with epoxide was found to possess high enantioselectivity, the optimal reaction temperature was enhanced 10 ℃, stability with time.
By employing immobilized enzyme as the biocatalyst in the kinetic resolution of racemic Naproxen trifluoroethyl ester via hydrolysis, agreements between the experimential data and best-fit results were found in which the Michaelis-Menten kinetic mechanism, coupled with effects product and enzyme deactivation were considered in the theoretical modeling. Moreover, the acid inhibition and the enhanced lipase activity were obtained when adding trioctylamine in the reaction medium.
