“…Consisting of a large number of aqueous micropools stably entrapped in macroscopically large silicone spheres (Figure 1),22 these particles combine provision of a distinct aqueous environment and large interfacial exchange area with high biocompatibility and appropriate mechanical strength. This has been demonstrated for BASE‐mediated direct esterification of biodiesel byproducts21 and recently in the synthesis of chiral hydroxy nitriles. Additional advantages arise from the use of low‐cost materials and simple preparation.…”

Literature reports biocatalytically active static emulsions (BASE) as promising systems for the preparation of biocatalysts designed for synthetic use in organic media. Their excellent catalytic performance is attributed to the numerous micropools of dissolved enzymes independently dispersed in silicone beads. Here, a systematic study of the structure and morphology of BASE and optimization in terms of bead size distribution and overall catalytic performance is presented. The study relies on beads obtained by using a novel preparation method that enables a considerably improved reproducibility of the particle size and catalytic activity in separate batches. A large interfacial area of 0.023 m2 g−1 material was calculated. The adjustment of bead composition increased the apparent catalytic activity of entrapped lipase A from Candida antarctica (CalA) to 0.71 U gBASE−1, which is almost twofold higher than that previously reported. The specific activity remained in the range of prototype BASE (0.21 U mgprotein−1), which nevertheless is about 53 times higher than that reported for CalA entrapped in a sol–gel.

“…These biocatalysts in static emulsions displayed much higher catalytic activity and stability than those entrapped in a sol–gel system, especially after the preparation protocol was optimized [91] . Such static emulsions have been successfully deployed to entrap different lipases, including Candida Antarctica lipase A (CalA), [90] Pseudomonas stutzeri lipase (lipase TL), [92] lipase of T. lanuginosa , [93] lipase from Burkholderia cepacia , [94] and hydroxynitrile lyase, [95] indicating their versatility for fabricating biocatalytic systems for a broad range of bioconversions.…”

Biocatalysis is increasingly being explored for the sustainable development of green industry. Though enzymes show great industrial potential with their high efficiency, specificity, and selectivity, they suffer from poor usability and stability under abiological conditions. To solve these problems, researchers have fabricated nano‐ and micro‐sized biocatalytic reactors based on the self‐assembly of various polymers, leading to highly stable, functional, and reusable biocatalytic systems. This Review highlights recent progress in self‐assembled polymeric nano‐ and microreactors for biocatalytic synthesis, including polymersomes, reverse micelles, polymer emulsions, Pickering emulsions, and static emulsions. We categorize these reactors into monophasic and biphasic systems and discuss their structural characteristics and latest successes with representative examples. We also consider the challenges and potential solutions associated with the future development of this field.

S Heute bekannte Enzyme katalysieren nahezu alle in der Chemie gängigen Reaktionstypen. 1) Das zelltoxische Acrylamid ist ein Beispiel eines bereits großtechnisch etablierten Enzymprodukts. 2) Besonders attraktiv ist die synthetisch-technische Nutzung von Enzymen, wenn es um Ressourceneffizienz und Umweltverträglichkeit chemischer Prozesse geht. Prognosen gehen davon aus, dass Enzyme zunehmend in der chemischen Produktion eingesetzt werden. 3)
