Covalent Immobilization of Laccase on Mesoporous Bismuth Silicate for High‐Performance Biodegradation of Contaminants

European Journal of Inorganic Chemistry, EarlyView.
Myceliophthora thermophila laccase covalently immobilized on bismuth silicate (BiSi‐ext) achieved synergistic adsorption–biodegradation of Tectilon Blue 4R‐01 and ibuprofen. The biocatalyst showed enhanced stability, reusability, and rapid pollutant removal via expanded active‐site accessibility, enabling efficient, eco‐friendly wastewater remediation.

Genetic diversity of the forage peanut in the Jequitinhonha, São Francisco, and Paranã River valleys of Brazil

Genetics and Molecular Research, 2016
Arachis pintoi and A. repens are legumes with a high forage value that are used to feed ruminants in consortium systems. Not only do they increase the persistence and quality of pastures, they are also used for ornamental and green cover. The objective of this study was to analyze microsatellite markers in order to access the genetic diversity of 65 ...

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

Environmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...
