Abstract
Exploring efficient immobilized carrier for α-Amylase (α-Amy) to enhance its thermostability has significant influence in starch related industry. Here, hollow ZIF-8 (HZIF-8) with amino groups coated magnetic phase change microcapsules (PCM) was designed for covalent immobilization of α-Amy. Magnetic PCM consisting n-docosane core and SiO2/Fe3O4 hybrid shell were firstly synthesized. Then, HZIF-8 shell with amino groups was coated and α-Amy was subsequently immobilized through covalent cross-linking strategy. The morphology, chemical structure and magnetic property of PCM@HZIF-8@α-Amy (PCMHA) were comprehensively characterized. Moreover, heat control property of PCMHA was studied with encapsulation efficiency and thermal energy-storage efficiency of 50.55 % and 50.59 %, respectively. Catalytic activity of immobilized α-Amy was fully investigated with Km and Vmax of 2.773 mg/mL and 1.853 μmol/mL·min, respectively. From reusability and storage stability study, immobilized α-Amy not only maintained rather high activity after 9 cycles' reuse, but also exhibited good activity under high salt ion condition after 7 days.

Enzyme immobilization technology as a tool to innovate in the production of biofuels: A special review of the Cross-Linked Enzyme Aggregates (CLEAs) strategy. Enzyme Microb Technol 2023; 170:110300. [PMID: 37523882 DOI: 10.1016/j.enzmictec.2023.110300] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 07/19/2023] [Accepted: 07/24/2023] [Indexed: 08/02/2023]
Abstract
This review emphasizes the crucial role of enzyme immobilization technology in advancing the production of two main biofuels, ethanol and biodiesel, with a specific focus on the Cross-linked Enzyme Aggregates (CLEAs) strategy. This method of immobilization has gained attention due to its simplicity and affordability, as it does not initially require a solid support. CLEAs synthesis protocol includes two steps: enzyme precipitation and cross-linking of aggregates using bifunctional agents. We conducted a thorough search for papers detailing the synthesis of CLEAs utilizing amylases, cellulases, and hemicellulases. These key enzymes are involved in breaking down starch or lignocellulosic materials to produce ethanol, both in first and second-generation processes. CLEAs of lipases were included as these enzymes play a crucial role in the enzymatic process of biodiesel production. However, when dealing with large or diverse substrates such as lignocellulosic materials for ethanol production and oils/fats for biodiesel production, the use of individual enzymes may not be the most efficient method. Instead, a system that utilizes a blend of enzymes may prove to be more effective. To innovate in the production of biofuels (ethanol and biodiesel), enzyme co-immobilization using different enzyme species to produce Combi-CLEAs is a promising trend.

Abstract
Mannan oligosaccharides (MOSs) are excellent prebiotics that are usually obtained via the enzymatic hydrolysis of mannan. In order to reduce the cost of preparing MOSs, immobilized enzymes that demonstrate good performance, require simple preparation, and are safe, inexpensive, and reusable must be developed urgently. In this study, β-mannanase was immobilized on calcium alginate (CaAlg). Under the optimal conditions of 320 U enzyme addition, 1.6% sodium alginate, 2% CaCl2, and 1 h of immobilization time, the immobilization yield reached 68.3%. The optimum temperature and pH for the immobilized β-mannanase (Man-CaAlg) were 75 °C and 6.0, respectively. The Man-CaAlg exhibited better thermal stability, a high degree of pH stability, and less substrate affinity than free β-mannanase. The Man-CaAlg could be reused eight times and retained 70.34% of its activity; additionally, the Man-CaAlg showed 58.17% activity after 30 days of storage. A total of 7.94 mg/mL of MOSs, with 4.94 mg/mL of mannobiose and 3.00 mg/mL of mannotriose, were generated in the oligosaccharide production assay. It is believed that this convenient and safe strategy has great potential in the important field of the use of immobilized β-mannanase for the production of mannan oligosaccharides.

Abstract
Enzymatic utilization of starch solid wastes is promising but hindered by its high cost. Enzymes immobilization is one solution; however, the key challenge remains the low mass transfer rate between the solid immobilization system and the solid wastes. Herein, an enzymatic modification strategy was applied instead of the traditional immobilization method. A novel system composed of poly(methacrylic acid), polyacrylic acid, and gelatin was firstly prepared and then used to modify α-amylase and glucoamylase to endow them with upper critical solution temperature (UCST) characteristic. As a result, we found that the wastes can be hydrolyzed efficiently with the modified co-enzymes above UCST and can be easily recovered and separated below UCST, thus the cost of starch wastes treatment can be largely reduced. Besides, the proposed method exhibited excellent environmental-friendly and bio-safety properties. Therefore, this method laid a solid foundation for efficient and cost-effective enzymatic conversion of starch solid wastes.

Designing multifunctional biocatalytic cascade system by multi-enzyme co-immobilization on biopolymers and nanostructured materials. Int J Biol Macromol 2023; 227:535-550.

Abstract
In recent decades, enzyme-based biocatalytic systems have garnered increasing interest in industrial and applied research for catalysis and organic chemistry. Many enzymatic reactions have been applied to sustainable and environmentally friendly production processes, particularly in the pharmaceutical, fine chemicals, and flavor/fragrance industries. However, only a fraction of the enzymes available has been stepped up towards industrial-scale manufacturing due to low enzyme stability and challenging separation, recovery, and reusability. In this context, immobilization and co-immobilization in robust support materials have emerged as valuable strategies to overcome these inadequacies by facilitating repeated or continuous batch operations and downstream processes. To further reduce separations, it can be advantageous to use multiple enzymes at once in one pot. Enzyme co-immobilization enables biocatalytic synergism and reusability, boosting process efficiency and cost-effectiveness. Several studies on multi-enzyme immobilization and co-localization propose kinetic advantages of the enhanced turnover number for multiple enzymes. This review spotlights recent progress in developing versatile biocatalytic cascade systems by multi-enzyme co-immobilization on environmentally friendly biopolymers and nanostructured materials and their application scope in the chemical and biotechnological industries. After a succinct overview of carrier-based and carrier-free immobilization/co-immobilizations, co-immobilization of enzymes on a range of biopolymer and nanomaterials-based supports is thoroughly compiled with contemporary and state-of-the-art examples. This study provides a new horizon in developing effective and innovative multi-enzymatic systems with new possibilities to fully harness the adventure of biocatalytic systems.

Abstract
Stimuli-responsive polymer enzyme reactors have become a major area of research interest, from their fundamental aspects to applications in bio-living science. However, the polymer materials, that enable the controllable enzymolysis based on ultraviolet-visible (UV)-responsive properties, have remained unexplored. Herein, an enzyme reactor was fabricated by immobilization of l-asparaginase on an UV-responsive porous polymer membrane (UV-PPMER), which consisted of poly(styrene-maleicanhydride-4-[(4-methacryloyloxy)phenylazo]benzoic acid) [P(St-MAn-MPABA)], and explored its controllable enzymolysis. By controlling the "on/off" switch of 365 nm UV irradiation, the configuration of polymer membrane surface changed to improve and tune the enzymolysis. Using l-asparagine (L-Asn) as the substrate, the enzymatic efficiency of the UV-PPMER was evaluated by a chiral capillary electrophoresis technique. Upon UV irradiation, the PMPABA moiety in the membrane changed from a trans- to a cisconfiguration and encapsulated the enzyme and substrate into a narrow cavity, further improving the enzymatic efficiency due to the confinement effect. It was found that the enzymatic reaction rate with the UV-PPMER under UV irradiation (13.3 mM min-1) was 4.5 times higher than that of UV irradiation was off (2.94 mM min-1). Additionally, the low cytotoxicity and excellent UV-responsivity of UV-PPMER were verified in the living cells and serum samples.
