Sodium alginate–entrapped laccase from solid-state cultures of Aspergillus oryzae as a promising system for asymmetric degradation of synthetic azo dyes

Laccase Immobilization on Tannic Acid–Coated Nylon Membrane for Dye Decolorization

Laccase catalyzes the oxidation of a wide array of substrates, yet its industrial applications are hindered by its low thermal and chemical stability, poor reusability, and high production costs. Enzyme immobilization is a cost-effective strategy for overcoming these limitations, enhancing stability and operational eff...

Heterogeneous biocatalysts based on porous polymer and lipase from Aspergillus niger obtained from SSC employing agroindustrial residues as raw material

This study aimed to produce extracellular lipases from Aspergillus niger using solid-state cultivation (SSC) of cottonseed bran and a blend of cottonseed bran and wheat bran (agroindustrial coproducts) as low-cost substrates. The highest activity (93.1 U/g dry mass) was achieved with cottonseed bran supplemented with c...

Laccase-mediated silver nanoparticles as a nano-biocatalytic pretreatment platform for enhanced saccharification and bioethanol production from sugarcane bagasse

Comparative degradation of azo dye cocktail by free and chitosan-immobilized fungal consortia with concomitant expression of lignin-modifying enzymes

Covalent immobilization of amyloglucosidase on magnetic-silver nanoparticles for rapid and reusable saccharification of cassava peel.

Efficient conversion of agricultural waste into fermentable sugars is central to sustainable second-generation biofuel technologies. This study reports the covalent immobilization of amyloglucosidase onto a magnetic silver nanoparticle (Ag-MNP) hybrid support for the saccharification of cassava peel. The Ag-MNP hybrid...

Biosynthesis of cyanophycin by high-cell-density cultivation of recombinant Escherichia coli for corrosion-resistant biomaterial applications

Cyanophycin granule polypeptide (CGP), also known as multi-l-arginyl-poly(aspartic acid), is a biodegradable biopolymer composed primarily of aspartic acid and arginine. Due to its versatile functional properties, CGP has attracted increasing interest for potential applications in food, medicine, cosmetics, agriculture...
