Abstract
Biocatalysis has emerged in the last decade as a pre-eminent technology for enabling the envisaged transition to a more sustainable bio-based economy. For industrial viability it is essential that enzymes can be readily recovered and recycled by immobilization as solid, recyclable catalysts. One method to achieve this is via carrier-free immobilization as cross-linked enzyme aggregates (CLEAs). This methodology proved to be very effective with a broad selection of enzymes, in particular carbohydrate-converting enzymes. Methods for optimizing CLEA preparations by, for example, adding proteic feeders to promote cross-linking, and strategies for making the pores accessible for macromolecular substrates are critically reviewed and compared. Co-immobilization of two or more enzymes in combi-CLEAs enables the cost-effective use of multiple enzymes in biocatalytic cascade processes and the use of “smart” magnetic CLEAs to separate the immobilized enzyme from other solids has raised the CLEA technology to a new level of industrial and environmental relevance. Magnetic-CLEAs of polysaccharide-converting enzymes, for example, are eminently suitable for use in the conversion of first and second generation biomass.

Abstract
The optically active C3 synthetic blocks are remarkably versatile intermediates for the synthesis of numerous pharmaceuticals and agrochemicals. This work provides a simple and efficient enzymatic synthetic route for the environment-friendly synthesis of C3 chiral building blocks. Chloroperoxidase (CPO)-catalyzed enantioselective halo-hydroxylation and epoxidation of chloropropene and allyl alcohol was employed to prepare C3 chiral building blocks in this work, including (R)-2,3-dichloro-1-propanol (DCP*), (R)-2,3-epoxy-1-propanol (GLD*), and (R)-3-chloro-1-2-propanediol (CPD*). The ee values of the formed C3 chiral building blocks DCP*, CPD*, and glycidol were 98.1, 97.5, and 96.7%, respectively. Moreover, the use of small amount of imidazolium ionic liquid enhanced the yield efficiently due to the increase of solubility of hydrophobic organic substrates in aqueous reaction media, as well as the improvement of affinity and selectivity of CPO to substrate.

Abstract
Herein, we reported here a promising biosensor by taking advantage of the unique ordered mesoporous carbon nitride material (MCN) to convert the recognition information into a detectable signal with enzyme firstly, which could realize the sensitive, especially, selective detection of catechol and phenol in compost bioremediation samples. The mechanism including the MCN based on electrochemical, biosensor assembly, enzyme immobilization, and enzyme kinetics (elucidating the lower detection limit, different linear range and sensitivity) was discussed in detail. Under optimal conditions, GCE/MCN/Tyr biosensor was evaluated by chronoamperometry measurements and the reduction current of phenol and catechol was proportional to their concentration in the range of 5.00 × 10(-8)-9.50 × 10(-6)M and 5.00 × 10(-8)-1.25 × 10(-5)M with a correlation coefficient of 0.9991 and 0.9881, respectively. The detection limits of catechol and phenol were 10.24 nM and 15.00 nM (S/N=3), respectively. Besides, the data obtained from interference experiments indicated that the biosensor had good specificity. All the results showed that this material is suitable for load enzyme and applied to the biosensor due to the proposed biosensor exhibited improved analytical performances in terms of the detection limit and specificity, provided a powerful tool for rapid, sensitive, especially, selective monitoring of catechol and phenol simultaneously. Moreover, the obtained results may open the way to other MCN-enzyme applications in the environmental field.

Abstract
Novel magnetic cross-linked enzyme aggregates of alpha amylase were prepared by chemical cross-linking of enzyme aggregates with amino functionalized magnetite nanoparticles which can be separated from reaction mixture using magnetic field. Of the initially applied alpha amylase activity 100% was recovered in magnetic CLEAs, whereas only 45% was recovered in CLEAs due to the low content of Lys residues in alpha amylase. Scanning electron microscopy analysis showed that CLEAs and magnetic CLEAs were spherical structures. The CLEAs and magnetic CLEAs displayed a shift in optimal pH towards the acidic side, whereas optimal temperature of magnetic CLEAs was improved compared to free enzyme and CLEAs. Although V(max) of enzyme in CLEAs and magnetic CLEAs did not change, substrate affinity of the enzyme increased. The magnetic CLEAs also enhanced the thermal stability and storage stability. Moreover, the magnetic CLEAs retained 100% initial activity even after 6 cycles of reuse.

Abstract
Cross-linked enzyme aggregates (CLEAs) have emerged as interesting biocatalyst design for immobilization. These new generation enzyme biocatalysts, CLEAs, in addition to exhibiting good mechanical stability, can be highly active, since they do not include large amounts of foreign particulate nonenzymatic material and may have increased stability. Naringinase (NGase) is an enzyme complex with high potential in pharmaceutical and food industries. In fact, NGase can be used in the biotransformation of steroids, of antibiotics and mainly on glycosides hydrolysis. In this paper, the formation of CLEAs was tried using ammonium sulphate, polyethylene glycol 6000 and tert-butyl alcohol as precipitant agents and glutaraldehyde as cross-linking agent, at different pH, time, and temperature conditions. However, among the precipitant agents tested, only tert-butyl alcohol cross-linked with glutaraldehyde allowed the formation of CLEAs, at pH 4.0 and at temperature between 7 and 10°C. Different enzyme loadings were tested. The NGase-CLEAs were highly effective in naringin hydrolysis. The operational stability of the NGase-CLEAs aggregates was studied through six successive reutilizations.

Abstract
Versatile peroxidase (VP) from Bjerkandera adusta was insolubilized in the form of cross-linked enzyme aggregates (CLEA®s). Of the initially applied activity 67% was recovered as CLEA®s. Co-aggregation of VP with glucose oxidase from Aspergillus niger led to an increased activity recovery of 89%. The combined CLEA®s showed higher stability against H(2)O(2) and exerted VP activity upon glucose addition. The elimination of the endocrine disrupting chemicals bisphenol A, nonylphenol, triclosan, 17α-ethinylestradiol and the hormone 17β-estradiol (10 mg L(-1) each) and the removal of their estrogenic activity by combined CLEA®s were tested in batch experiments. Within 10 min, the combined CLEA®s were able to remove all the endocrine disruptors except triclosan (residual concentration 74%). The removal of the estrogenic activity was higher than 55% for all compounds, except triclosan. A membrane reactor continuously operated with combined CLEA®s could almost completely remove bisphenol A (10 mg L(-1)) for 43 h.
