“…Therefore, some authors have proposed covalent linking, via crosslinking with glutaraldehyde [24][25][26] or EDC/NHS [27,28]. Also, the inclusion of new components into the composites has been often proposed, either to impart magnetic properties allowing their facile separation from reaction media [27,29], or to protect the enzyme by incorporating macromolecules like polyvinyl alcohol hydrogels [30] or by in situ formed self-assembled hybrid nanoflowers [31].…”

The industrial use of enzymes generally necessitates their immobilization onto solid supports. The well-known high affinity of enzymes for metal-organic framework (MOF) materials, together with the great versatility of MOFs in terms of structure, composition, functionalization and synthetic approaches, has led the scientific community to develop very different strategies for the immobilization of enzymes in/on MOFs. This review focuses on one of these strategies, namely, the one-pot enzyme immobilization within sustainable MOFs, which is particularly enticing as the resultant biocomposite Enzyme@MOFs have the potential to be: (i) prepared in situ, that is, in just one step; (ii) may be synthesized under sustainable conditions: with water as the sole solvent at room temperature with moderate pHs, etc.; (iii) are able to retain high enzyme loading; (iv) have negligible protein leaching; and (v) give enzymatic activities approaching that given by the corresponding free enzymes. Moreover, this methodology seems to be near-universal, as success has been achieved with different MOFs, with different enzymes and for different applications. So far, the metal ions forming the MOF materials have been chosen according to their low price, low toxicity and, of course, their possibility for generating MOFs at room temperature in water, in order to close the cycle of economic, environmental and energy sustainability in the synthesis, application and disposal life cycle.

“…PVA based materials have been used to entrap enzymes especially for biosensor applications due to their low cost, stability, recyclability, biocompatibility, and easy manipulation with different activation methods for enzyme immobilization [ 377 , 560 , 561 ]. Also PVA polymers are reported to have high mechanical strength which is an important attribute for an enzyme support [ 118 ].…”

“…However, PVA is susceptible to deformation at higher temperatures hence the biocatalyst can only be used for low temperature reactions [ 560 ]. To overcome that, PVA has been combined with other supports such as halloysite nanotubes [ 564 ], metal organic frameworks [ 561 ], alginate [ 377 ], xylan [ 565 ] and mesoporous silica [ 328 ].…”

“…Environmental pollution can also be caused by Anthraquinones (AQs) which can be found in personal care products, dyes or even some pharmaceutical products [126]. Although some researchers found that laccase removed 72% of the AQ dye in 60 min [127], in paper [128], scientists proposed alizarin green, a typical AQ, for testing the biodegradation ability of the immobilized laccase. A laccase immobilized on a metal-organic framework/polyvinyl-alcohol-cryogel as a substrate was studied in relation to wastewater pollution from personal care products, dyes, and pharmaceutical products.…”

The accumulation of waste and toxic compounds has become increasingly harmful to the environment and human health. In this context, the use of laccases has become a focus of interest, due to the properties of these versatile enzymes: low substrate specificity, and water formation as a non-toxic end product. Thus, we begin our study with a general overview of the importance of laccase for the environment and industry, starting with the sources of laccases (plant, bacterial and fungal laccases), the structure and mechanism of laccases, microbial biosynthesis, and the immobilization of laccases. Then, we continue with an overview of agro-waste treatment by laccases wherein we observe the importance of laccases for the biodisponibilization of substrates and the biodegradation of agro-industrial byproducts; we then show some aspects regarding the degradation of xenobiotic compounds, dyes, and pharmaceutical products. The objective of this research is to emphasize and fully investigate the effects of laccase action on the decomposition of lignocellulosic materials and on the removal of harmful compounds from soil and water, in order to provide a sustainable solution to reducing environmental pollution.
