Date: mar-01. 2020.
Doi: 10.3390/molecules25051220.

This work deals with anomalous concentrations of natural mordenite in the southeast of Spain. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) studies evidenced that the samples contain mainly monomineral zeolitic phase of mordenite (70% to 74%), usually accompanied by [read more]

Coimmobilization of different lipases: Simple layer by layer enzyme spatial ordering

Authors: Arana-Pena, S; Rios, NS; Mendez-Sanchez, C; Lokha, Y; Carballares, D; Goncalves, LRB; Fernandez-Lafuente, R

Doi: 10.1016/j.ijbiomac.2019.12.140.

A protein extract obtained from fig tree (Ficus carica) latex containing ficin activity was immobilized on glyoxyl agarose. Different biocatalyst loadings were used (3, 10, 30 and 85 mg/g). When casein was used as substrate, the expressed activities [read more]

Optimized immobilization of polygalacturonase from Aspergillus niger following different protocols: Improved stability and activity under drastic conditions

Authors: Dal Magro, L; Kornecki, JF; Klein, MP; Rodrigues, RC; Fernandez-Lafuente, R
