“…Nowadays, catalytic membranes are not limited to one-enzyme preparations. The variety of functional groups on the membrane surface facilitates the creation of co-immobilized preparations [ 23 , 24 ]. Their application is particularly recommended for biocatalytic processes with inhibition by-product [ 25 ] Bioconversion based on co-immobilized enzymes limits the accumulation of side products, decreases the number of steps of the process (one-pot mode), and reduces the idle time [ 26 ].…”

The growing need in the current market for innovative solutions to obtain lactose-free (L-F) milk is caused by the annual increase in the prevalence of lactose intolerance inside as well as the newborn, children, and adults. Various configurations of enzymes can yield two distinct L-F products: sweet (β-galactosidase) and unsweet (β-galactosidase and glucose oxidase) L-F milk. In addition, the reduction of sweetness through glucose decomposition should be performed in a one-pot mode with catalase to eliminate product inhibition caused by H2O2. Both L-F products enjoy popularity among a rapidly expanding group of consumers. Although enzyme immobilization techniques are well known in industrial processes, new carriers and economic strategies are still being searched. Polymeric carriers, due to the variety of functional groups and non-toxicity, are attractive propositions for individual and co-immobilization of food enzymes. In the presented work, two strategies (with free and immobilized enzymes; β-galactosidase NOLA, glucose oxidase from Aspergillus niger, and catalase from Serratia sp.) for obtaining sweet and unsweet L-F milk under low-temperature conditions were proposed. For free enzymes, achieving the critical assumption, lactose hydrolysis and glucose decomposition occurred after 1 and 4.3 h, respectively. The tested catalytic membranes were created on regenerated cellulose and polyamide. In both cases, the time required for lactose and glucose bioconversion was extended compared to free enzymes. However, these preparations could be reused for up to five (β-galactosidase) and ten cycles (glucose oxidase with catalase). Graphical abstract

“…Among them, polyvinylidene fluoride (PVDF) films are one of the most used polymer films to construct MOFs/polymer hybrid membranes, because of their excellent thermal stability, mechanical strength and porous nature. 39,40 In our previous work, the hybrid membranes of DUT-5/PVDF, ZIF-67/PVDF, MIL-68(Al)/PVDF and NH 2 -MIL-101(Cr)/PVDF 7,8,41,42 were fabricated and used in solid adsorption. Lyotropic phase transition and simple mechanical blending strategies were employed in the synthesis of these hybrid membranes.…”

In order to co‐immobilize multiple enzymes, a wide range of nanomaterials has been designed to achieve synergistic enzyme activity and enhance catalytic efficiency. Nanomaterials, as carriers for enzyme co‐immobilization, possess various advantages such as tunable morphology and size, high specific surface area, and abundant chemically active sites. They can significantly enhance enzyme stability, activity, and catalytic efficiency. We overview the commonly used methods and strategies of enzyme co‐immobilization. This review further summarizes the latest research advances in nanomaterials for enzyme co‐immobilization applications over the past 5 years. Meanwhile, the advantages and challenges of these nanomaterials used for enzyme co‐immobilization as well as some potential future directions are also discussed.
