Application in the Ethanol Fermentation of Immobilized Yeast Cells in Matrix of Alginate/Magnetic Nanoparticles, on Chitosan-Magnetite Microparticles and Cellulose-coated Magnetic Nanoparticles [PDF]

International Review of Chemical Engineering, Vol. 3, N. 2, March 2011 ( Int. Rev. Chem. Eng., 3(2011) 289 - 299 ), 2011
Saccharomyces cerevisiae cells were entrapped in matrix of alginate and magnetic nanoparticles and covalently immobilized on magnetite-containing chitosan and cellulose-coated magnetic nanoparticles. Cellulose-coated magnetic nanoparticles with covalently immobilized thermostable {\alpha}-amylase and chitosan particles with immobilized glucoamylase ...

Sustained Release of Proteins Using Region‐Specific Tunable Degradability in Hydrogels through 3D Photopatterning and Complimentary Labile Bond Chemistry

Advanced Functional Materials, EarlyView.
A series of ultraviolet‐ and near‐infrared radiation sensitive photoactivatable hydrogels are developed that can be controlled spatiotemporally down to µm precisions using one‐ and two‐photon uncaging. The latent hydroxylamine‐, hydrazine‐, and amine uncaged moieties are used to photopattern a series of diverse proteins displaying complimentary ...

Polymerization of Phenol using Free and Immobilized Horseradish Peroxidase [PDF]

, 2012
Phenol is a toxic compound and need to be treated before discharged. Phenol polymerization has been studied using free and immobilized Horse Radish Peroxidase (HRP). During the study period the ambient room temperature was between 27-32oC.

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.

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.

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 ...

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 ...
