Abstract Enzyme activity in nonaqueous media (e.g. conventional organic solvents) is typically lower than in water by several orders of magnitude. There is a rising interest of developing new nonaqueous solvent systems that are more “water-like” and more biocompatible. Therefore, we need to learn from the current state of nonaqueous biocatalysis to overcome its bottleneck and provide guidance for new solvent design. This review firstly focuses on the discussion of how organic solvent properties ...

A Computational Fluid Dynamics (CFD) study has been conducted to assess the performance of packed bed and coated wall microreactors for the steam reforming of methanol with a CuO/ZnO/Al2O3 based catalyst (BASF F3-01). The results obtained were compared to experimental data from the literature to assess the validity and robustness of the models, and a good validation has been obtained. The performance of the packed bed and coated wall microreactors is similar at a constant reforming temperature. ...

Industrial biocatalysts are gaining popularity each day for the purpose of eco-friendliness, cost-effectiveness and long-term sustainability. However, finding a suitable biocatalyst for any particular process fulfilling these criteria is still a challenging task and has to be taken care of for upscaling of the process. Emerging technologies are being adopted for the betterment of the process involving biocatalysis in terms of process economics and efficiency in terms of yield and productivity. V...

Abstract Enzymatic immobilization has been at the forefront of applied biocatalysis as it enables convenient isolation and reuse of the catalyst if the target reaction is conducted in batch, and it has opened up significant opportunities to conduct biocatalysis in continuous mode. Over the last few years, an array of techniques to immobilize enzymes have been developed, spanning from covalent multipoint attachment to noncovalent electrostatic strategies to rational architecture to suitably orien...

Abstract The preparation, characterization and application of a novel robust nanobiocatalyst, developed through the covalent binding of lipase B from Pseudozyma antarctica on magnetic hierarchically porous carbon materials (HPCFe), is reported. The nanobiocatalyst was characterized by combination of spectroscopic and microscopic techniques. Structural and catalytic characterization indicates that HPCFe nanostructures create a microenvironment which stabilizes the structure of the immobilized enz...

We report the first application of hydrophobic interaction between graphene oxide (GO) and negatively charged enzymes to fabricate CE‐integrated immobilized enzyme microreactors (IMERs) by a simple and reliable immobilization procedure based on layer by layer assembly. L‐lactate dehydrogenase (L‐LDH), which is negatively charged during the enzymatic reaction, is selected as the model enzyme. Various spectroscopic techniques, including SEM, FTIR, and UV‐vis are used to characterize the fabricated...

Salidroside, a phenylpropanoid glycoside, is a main bioactive component of Rhodiola rosea L. Previous studies have indicated that salidroside has prominent anti-stroke effects in cerebral ischemia/reperfusion models. But the underline mechanisms involved are not well understood. This study was designed to illustrate the anti-stroke effects of salidroside on MCAO-induced models in rats and its potential mechanisms on dopaminergic system. We discovered that administration with salidroside increase...

Abstract The use of immobilized enzymes is now a routine process for the manufacture of many industrial products in the pharmaceutical, chemical and food industry. Some enzymes, such as lipases, are naturally robust and efficient, can be used for the production of many different molecules and have a wide range of industrial applications thanks to their broad selectivity. As an example, lipase from Candida antarctica (CalB) has been used by BASF to produce chiral compounds, such as the herbicide ...
