Resumen:
The xylanase from Thermomyces lanuginosus was immobilized following very different protocols, using 3-aminopropyl (Xyl/CNT-NH2) and carboxylic acid (Xyl/CNT-C) functionalized multi-walled carbon nanotubes or after glutaraldehyde activation of CNT-NH2 (Xyl/CNT-Glu). It was also immobilized on carboxylic acid functionalized multi-walled carbon nanotubes [read more]

Resumen:
The first step of the inactivation of the enzyme D-amino acid oxidase (DAAO) from porcine kidney at pH 5 and 7 is the enzyme subunit dissociation, while FAD dissociation has not a relevant role. At pH 9, both dissociation phenomena affect the enzyme [read more]

Resumen:
Heterogeneous catalysts based on alumina-supported tungsten oxides (15 wt% W) with different loadings of nickel (0.5, 1, 2, 4, 6, 8 and 10 wt% Ni) were selected to study the influence of Ni loading on the hydroisomerization of [read more]

Resumen:
Lipase/metal nanobiohybrids, generated by growth of silver or gold nanoparticles on protein matrixes are used as highly effective dual-activity heterogeneous catalysts for the production of enantiomerically enriched 2,5-dihydrofurans from allenic acetates in a [read more]

Resumen:
We have studied the direct synthesis of hydrogen peroxide using a catalytic system consisting of palladium supported on silica bifunctionalized with sulfonic acid groups and bromide in the absence of acid and halide promoters in solution. Catalysts with several [read more]

Resumen:
High yield production of benzaldehyde in the solvent-free oxidation of benzyl alcohol by using green catalysts is highly desirable. In this work, calcium hydroxide derived from waste clamshell was used as low-cost and environmentally friendly catalyst support (CaSUP) for [read more]
