“…Higher number of reuses in hydrolysis reactions is expected since these reactions are carried out in mild conditions and shorter time intervals than the esterification/ transesterification reactions (Table 4). [41][42][43][44] Studies that reused lipases immobilized on biodegradables films for esters synthesis presented similar results to those reported in this work. CS-PVA-SS films produced with silkworm cocoons can be considered a promising biosupport for B. ribis EC-01 lipases immobilization.…”

An ecofriendly and low‐cost film composed by cassava starch, polyvinyl alcohol, and sericin blend (CS–PVA–SS) was synthesized, characterized, and applied as a novel support for Botryosphaeria ribis EC‐01 lipase immobilization by enzyme–film–enzyme adsorption. Film revealed thickness between 230 and 309 μm and higher flexibility and malleability in comparison with film without SS. Based on p‐nitrophenyl palmitate hydrolysis reaction, the activity retention of immobilized lipase was 987%. For optimal conditions, the yield in ethyl oleate was 95% for immobilized enzyme. Maximum yield was obtained at 49°C, molar ratio oleic acid:ethanol of 1:3, 1.25 g lipase film or 50 U (1.03 ± 0.03 mg protein) and 30 h. Even after seven cycles of use, immobilized lipase showed 52% reduction in ester yield. Biodegradable and biorenewable film is a promising material as a support to immobilize lipases and application in biocatalysis.

“…15 Recently, considerable advances have been made in industrial production of biodiesel and food grade ethyl esters using enzyme mediated approaches. 35,36 The present study investigates the possibility of using lipase microreactors for the transesterication of triacylglycerols into FAAE for GC analyses as an alternative to the widely used chemical procedures for derivatization to FAMEs. 16-21 A challenge to the success of a biocatalytic process is the cost of the enzyme and ensuring its reusability under the reaction conditions.…”

A flow-through enzymatic microreactor for the rapid conversion of triacylglycerols into fatty acid ethyl ester and fatty acid methyl ester derivatives for GC analysis

A flow-through enzymatic microreactor for the rapid conversion of triacylglycerols (TAG) into fatty acid ethyl ester (FAEE) or fatty acid methyl ester (FAME) derivatives was developed. The microreactor was a porous silica monolith fabricated within a 320 mm ID fused silica capillary with lipase from Candida antarctica immobilized onto the large surface area of the monolith. The microreactor was used for the room temperature ethanolysis of TAG from edible oils including canola, sesame, soybean and refinedbleached-deodorized palm oil. GC/MS-NCI and GC/FID were used to prove the identification of the FAEE and FAME products. The microreactor completely transformed the starting oils into FAEEs or FAMEs, without the use of any reagents other than alcohol, in quantities suitable for GC analysis. The prototype microreactors were reusable >5 times with ethanol and 2 times with methanol. The FAEE products obtained using the microreactor were similar to those produced using commercial Novozyme 435 enzyme beads as well as by catalysis with ethanolic H 2 SO 4 .

“…High DMC yield (93%) has been reported in Equation 6, for example, at 333 K and the molar ratio of methanol/ethylene carbonate of 16 (Liu et al, 2013). There have been a lot of reports on the transesterification of ethylene carbonate as summarized in a previous review (Santos et al, 2014).…”

Reaction of CO 2 with alcohols to organic carbonates is one of non-reductive CO 2 conversion methods. The catalysts are needed for this reaction, at the same time, effective H 2 O removal methods are also needed because the yield of organic carbonates is strongly limited by the equilibrium. The development of heterogeneous catalysts for the synthesis of dimethyl carbonate from CO 2 and methanol, which is a model and typical reaction, is described. This is because heterogeneous catalysts are more suitable to the practical process than homogeneous catalysts from the viewpoint of the separation of catalysts from the products and the reusability of the catalysts. One of the reported heterogeneous catalysts is CeO 2 , and it has been also reported that the combination of dimethyl carbonate synthesis from CO 2 and methanol with the hydration of nitriles such as 2-cyanopyridine, where both reactions are catalyzed by CeO 2 , enabled high yield of the carbonate. In addition, the combination of CeO 2 catalyst + nitriles can be applied to the synthesis of a variety of linear-, cyclic (five-and six-membered ring)-, and poly-carbonates from CO 2 and corresponding alcohols.
