Immobilization of Glucose Oxidase on Eupergit C: Impact of Aeration, Kinetic and Operational Stability Studies of Free and Immobilized Enzyme [PDF]

open access: yesChemical and Biochemical Engineering Quarterly, 2019
The effect of aeration on the stability of glucose oxidase in the reaction of glucose oxidation to gluconic acid was investigated by determining the operational stability decay rate constant in the process conditions.

A holistic carrier-bound immobilization approach for unspecific peroxygenase

open access: yesFrontiers in Chemistry, 2022
Unspecific peroxygenases (UPOs) are among the most studied enzymes in the last decade and their well-deserved fame owes to the enzyme’s ability of catalyzing the regio- and stereospecific hydroxylation of non-activated C–H bonds at the only expense of ...

Tuning Immobilized Commercial Lipase Preparations Features by Simple Treatment with Metallic Phosphate Salts

open access: yesMolecules, 2022
Four commercial immobilized lipases biocatalysts have been submitted to modifications with different metal (zinc, cobalt or copper) phosphates to check the effects of this modification on enzyme features. The lipase preparations were Lipozyme®TL (TLL-IM)

Stabilization of Enzymes in Silk Films [PDF]

open access: yesBiomacromolecules, 2009
Material systems are needed that promote stabilization of entrained molecules, such as enzymes or therapeutic proteins, without destroying their activity. We demonstrate that the unique structure of silk fibroin protein, when assembled into the solid state, establishes an environment that is conducive to the stabilization of entrained proteins. Enzymes

Simple Enzyme Immobilization for Flow Chemistry? An Assessment of Available Strategies for an Acetaldehyde-Dependent Aldolase

open access: yesMolecules, 2022
Enzyme immobilization is a technology that enables (bio-)catalysts to be applied in continuous-flow systems. However, there is a plethora of immobilization methods available with individual advantages and disadvantages. Here, we assessed the influence of

Data-driven enzyme immobilisation: a case study using DNA to immobilise galactose oxidase

open access: yesEngineering Biology, 2020
Biocatalysis has the potential to enable green chemistry. New methods of enzyme immobilisation will be required to improve enzyme stability, product purification, and compatibility of different enzymes in the same reaction conditions.

The Effect of Calcium Alginate Entrapment on the Stability of Novel Lipases from P. Reinekei and P. brenneri

open access: yesTrends in Peptide and Protein Sciences, 2019
The high cost of soluble enzymes can limit their use for commercial and industrial purposes. Immobilization can enhance enzyme reusability, thereby reducing product isolation costs and overcoming this economic barrier.

Stabilization of the Cellulase Enzyme Complex as Enzyme Nanoparticle

open access: yesApplied Biochemistry and Biotechnology, 2012
The native Celluclast BG cellulase enzyme complex consists of different enzymes which can also degrade great substrate molecules as native celluloses. This enzyme complex has been covered by a very thin, a few nanometers thick, polymer layer, in order to improve its stability.

Practical insights on enzyme stabilization [PDF]

open access: yesCritical Reviews in Biotechnology, 2017
Enzymes are efficient catalysts designed by nature to work in physiological environments of living systems. The best operational conditions to access and convert substrates at the industrial level are different from nature and normally extreme. Strategies to isolate enzymes from extremophiles can redefine new operational conditions, however not always ...
