Abstract
A leading biotechnological advancement in the field of biocatalysis is the immobilization of enzymes on solid supports to create more stable and recyclable systems. Metal-organic frameworks (MOFs) are porous materials that have been explored as solid supports for enzyme immobilization. Composed of organic linkers and inorganic nodes, MOFs feature empty void space with large surface areas and have the ability to be modified post-synthesis. Our target enzyme system for immobilization is glucose oxidase (GOx) and chloroperoxidase (CPO). Glucose oxidase catalyzes the oxidation of glucose and is used for many applications in biosensing, biofuel cells, and food production. Chloroperoxidase is a fungal heme enzyme that catalyzes peroxide-dependent halogenation, oxidation, and hydroxylation. These two enzymes work sequentially in this enzyme system by GOx producing peroxide, which activates CPO that reacts with a suitable substrate. This study focuses on using a zirconium-based MOF, UiO-66-NH2, to immobilize the enzyme system via crosslinking with the MOF’s amine group on the surface of the MOF. This study investigates two different crosslinkers: disuccinimidyl glutarate (DSG) and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC)/N-hydroxysuccinidimide (NHS), providing stable crosslinking of the MOF to the enzymes. The two crosslinkers are used to covalently bond CPO and GOx onto UiO-66-NH2, and a comparison of the recyclability and enzymatic activity of the single immobilization of CPO and the doubly immobilized CPO and GOx is discussed through assays and characterization analyses. The DSG-crosslinked composites displayed enhanced activity relative to the free enzyme, and all crosslinked enzyme/MOF composites demonstrated recyclability, with at least 30% of the activity being retained after four catalytic cycles. The results of this report will aid researchers in utilizing CPO as a biocatalyst that is more active and has greater recyclability.

Abstract
AbstractChloroperoxidase from Caldariomyces fumago was immobilized in Eupergit® C, a commercial mesoporous acrylic-based material. Due to low stability of the enzyme under neutral and basic pH, the usual covalent immobilization procedures cannot be applied to this enzyme. Several strategies were followed in order to achieve a stable interaction between the protein and the support. The support was efficiently functionalized with different reactive groups such as aromatic and aliphatic amines, glutaraldehyde, diazonium ions, and maleimide moieties; solvent-exposed amino acid residues in chloroperoxidase were identified or created through chemical modification, so that they were reactive under conditions where the enzyme is stable. Enzyme load and retained activity were monitored, obtaining biocatalysts with specific activity ranging from 200 to 25,000 U/g. The highest load and activity was obtained from the immobilization of a chemically-modified CPO preparation bearing a solvent-exposed free thiol group. This biocatalyst efficiently catalyzed the transformation of β-estradiol, an endocrine disruptor.

Abstract
In this work, the successful coupling of enzymatic oxidation and aldol addition reactions for the synthesis of a Cbz-aminopolyol from a Cbz-amino alcohol was achieved for the first time in a multienzymatic one-pot system. The two-step cascade reaction consisted of the oxidation of Cbz-ethanolamine to Cbz-glycinal catalyzed by chloroperoxidase from the fungus Caldariomyces fumago and aldol addition of dihydroxyacetone phosphate to Cbz-glycinal catalyzed by rhamnulose-1-phosphate aldolase expressed as a recombinant enzyme in Escherichia coli, yielding (3R,4S)-5-{[(benzyloxy)carbonyl]amino}-5-deoxy-1-O-phosphonopent-2-ulose. Tools of enzymatic immobilization, reactor configurations, and modification of the reaction medium were applied to highly increase the production of the target compound. While the use of soluble enzymes yielded only 23.6 % of Cbz-aminopolyol due to rapid enzyme inactivation, the use of immobilized ones permitted an almost complete consumption of Cbz-ethanolamine, reaching Cbz-aminopolyol yields of 69.1 and 71.9 % in the stirred-tank and packed-bed reactor, respectively. Furthermore, the reaction production was 18-fold improved when it was catalyzed by immobilized enzymes in the presence of 5 % (v/v) dioxane, reaching a value of 86.6 mM of Cbz-aminopoliol (31 g/L).

Abstract
Considerable effort has been dedicated to the chemical depolymerization of lignin, a biopolymer constituting a possible renewable source for aromatic value-added chemicals. However, these efforts yielded limited success up until now. Efficient lignin conversion might necessitate novel catalysts enabling new types of reactions. The use of multiple catalysts, including a combination of biocatalysts, might be necessary. New perspectives for the combination of bio- and inorganic catalysts in one-pot reactions are emerging, thanks to green chemistry-driven advances in enzyme engineering and immobilization and new chemical catalyst design. Such combinations could offer several advantages, especially by reducing time and yield losses associated with the isolation and purification of the reaction products, but also represent a big challenge since the optimal reaction conditions of bio- and chemical catalysis reactions are often different. This mini-review gives an overview of bio- and inorganic catalysts having the potential to be used in combination for lignin depolymerization. We also discuss key aspects to consider when combining these catalysts in one-pot reactions.

Abstract
Chloroperoxidase (CPO) was covalently immobilized on poly(hydroxypropyl methacrylate-co-polyethyleneglycole-methacrylate) membranes, which were characterized, by swelling test, FT-IR spectroscopy, scanning electron microscopy, and contact angle measurement. The Km and Vmax values for free and immobilized CPO were found to be 34.6 and 47.2 μM, and 287.5 and 245.2 U/mg protein, respectively. The optimum pH for both the free and immobilized enzyme was observed at 3.0. The immobilized enzyme showed wide pH and temperature profiles. Most importantly, the increased thermal, storage and operational stability of immobilized CPO should depend on the creation of a comfortable strong hydrophilic microenvironment on the designed support to the host enzyme molecule.

Abstract
The effects of several polyhydroxy compounds (glucose, fructose, gumsugar, galactose, trehalose, dextran, xylose, PEG200, glycerin) and surfactant (dioctyl sulfosuccinate sodium salt, AOT) on the catalytic activity and thermal stability of chloroperoxidase (CPO) in aqueous systems were investigated at various temperatures. A 25% superactivity was found in AOT solutions at 25 degrees C, and it could be maintained during the 882 h. PEG200 and glycerin were proven to be the most efficient stabilizer for CPO in temperatures ranging from 25 to 60 degrees C. Trehalose is more helpful than other sugars for extended storage of CPO. These results are promising in view of industrial applications of this versatile biological catalyst. The protective mechanism of various additives on CPO was discussed.

Abstract
Multipoint covalent immobilization of enzymes (through very short spacer arms) on support surfaces promotes a very interesting ‘rigidification’ of protein molecules. In this case, the relative positions of each residue of the enzyme involved in the immobilization process have to be preserved unchanged during any conformational change induced on the immobilized enzyme by any distorting agent (heat, organic solvents etc.). In this way, multipoint covalent immobilization should induce a very strong stabilization of immobilized enzymes. Epoxy-activated supports are able to chemically react with all nucleophile groups placed on the protein surface: lysine, histidine, cysteine, tyrosine etc. Besides, epoxy groups are very stable. This allows the performance of very long enzyme–support reactions, enabling us to get very intense multipoint covalent attachment. In this way, these epoxy supports seem to be very suitable to stabilize industrial enzymes by multipoint covalent attachment. However, epoxy groups exhibit a low intermolecular reactivity towards nucleophiles and hence the enzymes are not able to directly react with the epoxy supports. Thus a rapid physical adsorption of enzymes on the supports becomes a first step, followed by an additional rapid ‘intramolecular’ reaction between the already adsorbed enzyme and the activated support. In this situation, a suitable first orientation of the enzyme on the support (e.g. through regions that are very rich in nucleophiles) is obviously necessary to get a very intense additional multipoint covalent immobilization. The preparation of different ‘generations’ of epoxy supports and the design of different protocols to fully control the first interaction between enzymes and epoxy supports will be reviewed in this paper. Finally, the possibilities of a directed immobilization of mutated enzymes (change of an amino acid by cysteine on specific points of the protein surface) on tailor-made disulfide-epoxy supports will be discussed as an almost-ideal procedure to achieve very intense and very efficient rigidification of a desired region of industrial enzymes.

Abstract
The catalytic potential of chloroperoxidase (CPO) immobilized on mesoporous materials was evaluated for the oxidation of 4,6-dimethyldibenzothiophene in water/acetonitrile mixtures. Two different types of materials were used for the immobilization: a metal containing Al-MCM-41 material with a pore size of 26 A and SBA-16 materials with three different pore sizes: 40, 90 and 117 A. The SBA-16 40 A did not retain any CPO. The nature and the pore size of the material affected the catalytic activity of the enzyme as well as its stability. Compared to the free enzyme, the thermal stability of CPO at 45 degrees C was two and three times higher than when immobilized on Al-MCM-41 and SBA-16 90 A, respectively.

Abstract
In this study, very easily prepared trypsin-immobilized magnetic microspheres were applied in microwave-assisted protein digestion and firstly applied for proteome analysis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Magnetic microspheres with small size were synthesized and modified by 3-glycidoxypropyltrimethoxysilane (GLYMO). Trypsin was immobilized onto magnetic microspheres through only a one-step reaction of its amine group with GLYMO. When these easily prepared trypsin-immobilized magnetic microspheres were applied in microwave-assisted protein digestion, the magnetic microspheres not only functionalized as substrate for trypsin immobilization, but also as an excellent microwave absorber and thus improved the efficiency of microwave-assisted digestion greatly. Cytochrome c was used as a model protein to verify its digestion efficiency. Without any additives such as organic solvents or urea, peptide fragments produced in 15 s could be confidently identified by MALDI-TOF-MS and better digestion efficiency was obtained comparing to conventional in-solution digestion (12 h). Besides, with an external magnet, trypsin could be used repeatedly and at the same time no contaminants were introduced into the sample solution. It was verified that the enzyme maintained high activity after seven runs. Furthermore, reversed-phase liquid chromatography (RPLC) fractions of rat liver extract were also successfully processed using this novel method. These results indicated that this fast and efficient digestion method, which combined the advantages of immobilized trypsin and microwave-assisted protein digestion, will greatly hasten the application of top-down proteomic techniques for large-scale analysis in biological and clinical research.

Abstract
A novel reaction system was developed to maximize the catalytic efficiency of chloroperoxidase (CPO, from Caldariomyces fumago) toward the oxidation of hydrocarbons. The reaction system consisted of an organic/aqueous emulsion comprising pure substrate and aqueous buffer supplemented with the surfactant dioctyl sulfosuccinate. The emulsion system attenuated not only the destabilizing effects of the substrate and product on the enzyme by emulsifying the compounds, but also oxidant toxicity (oxidative stress) by increasing substrate availability. As a result, CPO exhibited total turnover numbers (TTNs, defined as the amount of product produced over the catalytic lifetime of the enzyme) of ca. 20,000 mol product/mol enzyme for the oxidation of styrene, toluene, and o-, m-, p-xylenes. The TTNs are over 10-fold higher than those previously reported for the oxidation of benzylic hydrocarbons by CPO. This study represents a significant step toward the development of CPO as a practical catalyst for large-scale organic syntheses.

Abstract
Micron-grade monodisperse PMMA microspheres, whose surfaces were modified with functional groups by co-polymerisation using functional monomer, were prepared via dispersion polymerisation. Characterized by their large specific surface area, high adsorption ability, favourable biocompatibility, these monodisperse micron-sized PMMA microspheres were employed as the supporting material in the enzyme immobilization in present work. The influential factors on the activity of immobilized enzyme including pH, temperature, time etc were preliminarily investigated. The results concluded from the experiments indicated that the immobilization procedure could promote the resistance of enzyme against temperature, pH shift and some other tough reaction conditions meanwhile prolong the enzymatic lifetime for storage.
