Enzymatic esterification of phytosterols is essential for their stability and bioavailability in lipophilic foods. In this study, we created a new polydopamine-based bowl-like mesoporous carrier (BLM-PDA) for lipase loading and catalyzed the esterification of phytosterols and oleic acid to produce oleate sterol ester. Candida rugosa lipase (CRL) was selected to immobilize the polymer using physical adsorption. SEM, TEM, XRD, TGA, XPS, FT-IR, and BET were used to characterize it in order to confirm the successful preparation. These less-studied asymmetric bowl-like particles showed much enhanced performance in all aspects. According to the findings, BLM-PDA had a lipase loading of around 126.05 mg g −1 , and the thermal stability and reusability of BLM-PDA@CRL fared particularly well in activity tests. After 55 h, the catalyst successfully completed the oleate sterol ester yield of 81.07% of the transesterification cycle at 40 °C. Therefore, it offers more suggestions for using an immobilized lipase nanoreactor to the biosynthesis of sterol esters.

“…As demonstrated by Jiang, Liu, and coworkers, ZIF-8 was coated on the surface of silica nanoflower immobilized with formate dehydrogenase -an enzyme that can electrocatalyze the reduction of CO 2 to produce formic acid. [27] The authors found that the ZIF-8 coating could not only protect the enzyme from leaching but also pre-concentrate the CO 2 near the surface; the electrocatalytic activity for CO 2 reduction could thus be enhanced with the help of the ZIF-8 coating (Figure 1(c)).…”

Stable and Electrochemically “Inactive” Metal−Organic Frameworks for Electrocatalysis

Metal−organic frameworks (MOFs) with ultrahigh surface areas and interconnected porosity have been considered as attractive materials for electrocatalysis. Numerous research efforts have thus been made to develop the “electrocatalytic MOFs”. But the poor stability in water and the low electrical conductivity of most MOFs strongly limit the direct use of such electrochemically active MOFs. In this article, we aim to highlight a different concept – utilizing stable but electrochemically “inactive” MOFs for electrocatalytic reactions. Though the porous framework does not exhibit electrocatalytic activity and is electrically insulating, it could modulate the microenvironment near the underlying surface of the electrocatalyst and thus adjust the reaction rates and selectivity of the complicated electrochemical reactions. Herein, such strategies reported previously are reviewed, and the potential opportunities in future studies are discussed.
