Doi: 10.1016/j.cattod.2022.12.005.

Abstract:
In the search for more efficient low-temperature catalysts able to oxidise biorecalcitrant pollutants in water, the selective substitution of La3+ by Ti3+ cations was reported to boost the UV-A light driven activity of LaFeO3 orthoferrites as H2O2-mediated photo-CWPO [read more]

Abstract:
In this work, intermetallic PdZn-ZnO catalysts supported on high surface area TiO2 were synthesized using metalorganic precursors and different Zn/Pd molar ratio (2.5, 5 and 7.5). The use of organic Pd and Zn precursors in the impregnation [read more]

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

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

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

Abstract:
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]
