BACKGROUND : Metal-organic frameworks (MOFs) have gained increasing attention with ever-expanding applications. Developing new MOF-based immobilized enzymes with new applications is required, not only for demonstrating the generality and applicability of using MOFs for enzyme immobilization, but also to provide potential biocatalysts for industrial applications. To the best of the authors’ knowledge, this is the first report of immobilizing mushroom tyrosinase on zeolitic imidazolate frameworks (ZIFs), with two new applications being developed. RESULTS : Upon immobilization through a one-pot in situ encapsulation approach, the resultant tyrosinase@ZIF-8 was characterized in structural features and catalytic properties. It was much more stable against pH and temperature relative to the free enzyme. The new biocatalyst was highly efficient in catalyzing the synthesis of catecholic products with pharmacol. benefits (L-DOPA, piceatannol and 3′-hydroxypterostilbene) and in eliminating phenolic pollutants (phenol, p-cresol, p-chlorophenol). Excellent productivities were obtained for the synthesis of the three catecholic products (0.14, 1.38 and 1.46 g L-1 h-1, resp.). A complete removal of the three phenolic pollutants was achieved within 2.5 h, superior to other processes mediated by the same enzyme, or others, immobilized on different supports. The reusability of the new biocatalyst can be remarkably improved by entrapment into polyvinyl alc.-alginate gel. CONCLUSIONS : Tyrosinase can be immobilized on a new type of MOF with advantages such as easy preparation and excellent catalytic performance. This novel immobilization strategy for tyrosinase offers an excellent biocatalyst potent for both catecholic product synthesis and phenolic wastewater treatment. 2021 Society of Chem. Industry (SCI). In the experiment, the researchers used many compounds, for example, (E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6SDS of cas: 10083-24-6).
(E)-4-(3,5-Dihydroxystyryl)benzene-1,2-diol (cas: 10083-24-6) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.SDS of cas: 10083-24-6
