Covalent immobilization of glucoamylase enzyme onto chemically activated surface of κ-carrageenan

open access: yesBulletin of the National Research Centre, 2019
Background Glucoamylase enzyme is one of the most important enzymes. It catalyzes the hydrolysis of starch into soluble sugars. It was covalently immobilized onto κ-carrageenan gel beads after activation by using polyethylenimine (PEI) followed by ...

Evaluation of fungal laccase immobilized on natural nanostructured bacterial cellulose

open access: yesFrontiers in Microbiology, 2015
The aim of this work was to assess the possibility of using native bacterial nanocellulose (BC) as a carrier for laccase immobilization. BC was synthesized by Gluconacetobacter xylinus, which was statically cultivated in a mannitol-based medium and was ...

Recycling of textile bleaching effluents for dyeing using immobilized catalase [PDF]

open access: yes, 2002
Catalase was immobilized on alumina carrier and crosslinked with glutaraldehyde. Storing stability, temperature and pH profiles of enzyme activity were studied in a column reactor with recirculation and in a batch stirred-tank reactor.
