Production of xylo-oligosaccharides by immobilized-stabilized derivatives of endo-xylanase from Streptomyces halstedii
(2013-03-01)
An endoxylanase from Streptomyces halstedii was stabilized by multipoint covalent immobilization on glyoxyl-agarose supports. The immobilized enzyme derivatives preserved 65% of the catalytic activity corresponding to the ...

Improving the properties of chitosan as support for the covalent multipoint immobilization of chymotrypsin
(American Chemical Society, 2008-07)
Changing gel structure and immobilization conditions led to a significant improvement in the covalent multipoint attachment of chymotrypsin on chitosan. The use of sodium alginate, gelatin, or κ-carrageenan, activation ...
A highly stable biocatalyst obtained from covalent immobilization of a non-commercial cysteine phytoprotease
(OMICS, 2015-05)
In this work, araujiain (enzymatic preparation obtained from the latex of Araujia hortorum fruits) was successfully immobilized on glyoxyl-agarose via multipoint covalent attachment. Thus, good efficiency of immobilization ...
Covalent immobilization of soybean seed hull urease on chitosan mini-spheres and the impact on their properties
(Elsevier, 2019-03)
Urease (EC 3.5.1.5) is found in bacteria, fungi, algae, plants and some invertebrates, and in soils. Soil ureases are partly extracellular being liberated during microbial and plant root metabolism and death. In plants, ...
Covalent Immobilization of Amino-beta-Cyclodextrins on Glassy Carbon Electrode in Aqueous Media
(2019)
In the present work, the application of the amine electrooxidation method to achieve the grafting of amino beta-cyclodextrins (CD-amines) on glassy carbon electrodes (GCE) in aqueous media has been investigated. The results ...
Immobilization and stabilization of a bimolecular aggregate of the lipase from Pseudomonas fluorescens by multipoint covalent attachment
(2013-01-01)
The soluble lipase from Pseudomonas fluorescens (PFL) forms bimolecular aggregates in which the hydrophobic active centers of the enzyme monomers are in close contact. This bimolecular aggregate could be immobilized by ...
