摘要
In the current years of heightened focus on green chemistry and sustainable materials, this study delves into the untapped potential of hyaluronic acid (HA), chitin, and chitosan-prominent polysaccharides for groundbreaking applications. The primary aim is to effectively immobilize catalase enzymes onto matrices composed of chitosan, chitin, HA/chitin, and HA/chitosan. The rigorous investigation covers a spectrum of structural enhancements encompassing pH and temperature stability, thermal resilience, half-life extension, storage durability, reusability, and comprehensive FTIR analyses of the catalase immobilization. Notably, catalase activity demonstrated remarkable resilience on HA/chitin and HA/chitosan matrices, maintaining 73.80% and 79.55% efficacy even after 25 cycles. The introduction of covalent cross-linking between catalase and HA/chitin or HA/chitosan, facilitated by a cross-linking agent, significantly amplified stability and recycling efficiency. Consequently, the immobilized catalase showcases substantial promise across a spectrum of industrial applications, spanning from food and detergent production to bioremediation and diverse commercial processes. This underscores its pivotal role as a versatile and invaluable innovation in the realm of sustainable technologies.
