Carbon dioxide/methanol conversion cycle based on cascade enzymatic reactions supported on superparamagnetic nanoparticles

Anais da Academia Brasileira de Ciências, 2017
The conversion of carbon dioxide into important industrial feedstock is a subject of growing interest in modern society. A possible way to achieve this goal is by carrying out the CO2/methanol cascade reaction, allowing the recycle of CO2 using either ...

Glucose oxidase immobilization onto carbon nanotube networking [PDF]

Ukrainian Journal of Physics, Vol. 57, No. 7, 2012, pp. 700-709, 2012
When elaborating the biosensor based on single-walled carbon nanotubes (SWNTs), it is necessary to solve such an important problem as the immobilization of a target biomolecule on the nanotube surface. In this work, the enzyme (glucose oxidase (GOX)) was immobilized on the surface of a nanotube network, which was created by the deposition of nanotubes ...

The protein cost of metabolic fluxes: prediction from enzymatic rate laws and cost minimization [PDF]

, 2016
Bacterial growth depends crucially on metabolic fluxes, which are limited by the cell's capacity to maintain metabolic enzymes. The necessary enzyme amount per unit flux is a major determinant of metabolic strategies both in evolution and bioengineering.

Reductive Biotransformation of Ethyl Acetoacetate: A Comparative Studies using Free and Immobilized Whole Yeast Cells [PDF]

, 2008
Bioreduction of ethyl acetoacetate with free and immobilized yeast whole cell was achieved by using water and sucrose combination. After detachment from immobilized beads under basic condition, the corresponding ethyl(S)-(+)-3-hydroxybutanoate was ...

Enzyme immobilization by adsorption: a review [PDF]

Adsorption, 2014
Endowed with unparalleled high catalytic activity and selectivity, enzymes offer enormous potential as catalysts in practical applications. These applications, however, are seriously hampered by enzymes’ low thermal and chemical stabilities. One way to improve these stabilities is the enzyme immobilization.

Graphene oxide immobilized enzymes show high thermal and solvent stability.

Nanoscale, 2015
The thermal and solvent tolerance of enzymes is highly important for their industrial use. We show here that the enzyme lipase from Rhizopus oryzae exhibits exceptionally high thermal stability and high solvent tolerance and even increased activity in ...

Sonochemical Functionalization of Glass

Advanced Functional Materials, EarlyView.
A new method for functionalizing glass using ultrasonication of aryl diazonium salts. Aryl radicals generated by ultrasounds react with glass, forming a stable, covalently bonded organic film. The functionalized glass adheres microorganisms such as microalgae, fungi, and bacteria, suggesting potential applications in enzyme production, filtration ...

Co-Immobilization of Alcalase/Dispase for Production of Selenium-Enriched Peptide from Cardamine violifolia

Foods
Enzymatically derived selenium-enriched peptides from Cardamine violifolia (CV) can serve as valuable selenium supplements. However, the industrial application of free enzyme is impeded by its limited stability and reusability.

Oxidation reactions are required to produce atranorin from acetate by alginate-immobilized cells of Cladonia verticillaris. [PDF]

, 2000
Atranorin, a p-depside of the b-orcinol series, is produced by several Cladonia species. Immobilized cells of Cladonia verticillaris in calcium alginate are able to produce atranorin when they are supplied with 1.0 mM acetate as a precursor.

Cell Membrane Vesicle Camouflaged Artificial Cells

Advanced Functional Materials, EarlyView.
Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...
