In this work lipase CaLB was immobilized on functionalized Pd-SiO2 nanoparticles in order to simplify the DKR of α-methylbenzylamine. Hybrid biocatalysts showed immobilization efficiencies of 82%, 80% and 76% when containing 1, 5 and 10% of Pd respectively. On DKR reaction values of ee > 99% and conversion of 82% were found with only 1% of Pd, generating a productivity of 2.21 mg of product h−1 mg

苄胺的DKR。当分别包含1、5和10%的Pd时,杂化
生物催化剂的固定化效率分别为82%,80%和76%。在DKR上,仅使用1%的Pd时,发现ee的反应值> 99%,转化率达到82%,相对于N435®的0.76 ,产生的生产率为2.21 mg产品h -1 mg载体-1。与商业化的N435®相比,新型
生物催化剂显示出较低的蛋白质负载量和较高的活性,高出15倍,显示出竞争优势和较高的工业应用价值。
