Immobilization-stabilization of the dimeric D-amino acid oxidase from porcine kidney

Authors: Carballares, D; Fernandez-Lafuente, R; Rocha-Martin, J

Process Biochem.. vol: 122. page: 1359-5113.
Date: NOV. 2022.
Doi: 10.1016/j.procbio.2022.10.002.

This paper shows the immobilization of the dimeric D-amino acid oxidase (DAAO) following different methodologies. Immobilization on glyoxyl-agarose yielded activity recoveries under 5%, and it was discarded. The anion exchange on aminated supports permits the rapid enzyme immobilization, but its activity decreased [read more]

Doi: 10.1016/j.ijbiomac.2022.08.155.

The immobilization of ficin (a cysteinyl proteases) on vinyl sulfone agarose produced its almost full inactivation. It was observed that the incubation of the free and immobilized enzyme in beta-mercaptoethanol produced a 20 % of enzyme activity recovery, suggesting that [read more]

Surface modification of Cu2O-CuO photocatalyst on Cu wire through decorating with TiO2 nanoparticles for enhanced visible light photocatalytic activity

Authors: Ansari, F; Sheibani, S; Fernandez-Garcia, M

Doi: 10.1016/j.jallcom.2022.165864.

In this paper, the fabrication of Cu2O-CuO/TiO2 nanocomposite photocatalysts on Cu wire was performed successfully via chemical-thermal oxidation and sol-gel process. The chemical-thermal oxidations were applied for Cu2O-CuO nanostructure fabrication on the Cu wire surface. The sol-gel process was utilized for [read more]

Optimization of the immobilization of xylanase from Thermomyces lanuginosus to produce xylooligosaccharides in a batch type reactor
