Cross-linked enzyme aggregates (CLEAs): stable and recyclable biocatalysts.
The key to obtaining an optimum performance of an enzyme is often a question of devising an effective method for its immobilization. In the present review, we describe a novel, versatile and effective methodology for enzyme immobilization as CLEAs (cross-linked enzyme aggregates). The method is exquisitely simple (involving precipitation of the enzyme from aqueous buffer followed by cross-linki...
متن کاملUse of Cross-Linked Enzyme Aggregates (CLEAs) for performing biotransformations
The methodology for the preparation of cross-linked enzyme aggregates (CLEAs) and their application as highly effective, recyclable biocatalysts in a wide variety of transformations is reviewed. The method constitutes a combination of enzyme purification and immobilization into a single operation and allows for the use of relatively crude enzyme preparations. The resulting CLEAs have excellent ...
متن کاملCross-linked Enzyme Aggregates of Catalase from Bovine Liver
Stabilization of multimeric enzymes is one of the major challenges in biocatalysis, because dissociation of subunits can inactivate the enzyme. Catalase (CAT; EC 1.11.16) is a homotetramer containing Fe-protoporphyrin IX in its active site. CAT breaks down hydrogen peroxide into water and molecular oxygen. In this study, crosslinked enzyme aggregates of bovine liver CAT (CAT-CLEAs) were prepare...
متن کاملApplication of magnetized Sawdust Cross-linked by polyethyleniminefor removal Zn2+ from aqueous solution
The need to elimination heavy metal from aqueous solutions cannot be over emphasized.Very studies have investigated the removal heavy metal from water. In this study a new magnetic nanocomposite of PEI on magnetized Sawdust (SD/MNP/PEI) was prepared. Investigations were conducted to study the adsorption behavior of heavy metal Zn (II) on the SD/MNP/PEI nanocomposite in aqueous medium by varying...
متن کاملRemoval efficiency of Enzyme Horseradish Peroxidase in Removal of Tetracycline and Ciprofloxacin from Synthetic Wastewater
Background and purpose: So far, different methods have been used to remove residual antibiotics from aquatic environments. This study investigated the efficiency of enzyme horseradish peroxidase (HRP) in presence of hydrogen peroxide in removal of Tetracycline and Ciprofloxacin in a batch system. Materials and methods: In an experimental study on laboratory scale, the effects of contact time, ...
