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.

Litsea cubeba Essential Oil Reduces Postharvest Blueberry Rot by Inducing Cell Membrane Damage and Reactive Oxygen Species Accumulation in Alternaria alternata

Future Postharvest and Food, EarlyView.
Litsea cubeba essential oil (LCEO) reduces blueberry rot while maintaining quality. It disrupts the cellular structure and membranes of Alternaria alternata, causing solute leakage, while simultaneously inducing reactive oxygen species (ROS) accumulation and mitochondrial membrane potential (MMP) damage in the pathogen.

Degradation of pigments in Limnospira platensis extracts

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Limnospira platensis, commonly known as spirulina, holds promise for application as a food ingredient and nutraceutical due to its rich protein and antioxidant content, including chlorophylls, carotenoids and phycocyanin. Despite its potential, the vibrant colour poses a challenge for consumer acceptance, hampering the marketability
