Résumé

This work was developed to explore the versatility of thermophilic esterase for decolorizing raw molasses wastewater at high temperature and acidic pH. Combining covalent crosslinking method with deep eutectic solvent, a thermophilic esterase from Pyrobaculum calidifontis was immobilized on chitosan/macroporous resin composite carrier. The application of this immobilized thermophilic esterase eliminated 92.35% of colorants in raw molasses wastewater, achieving maximal decolorization efficiency across all the enzymes tested. Strikingly, this immobilized thermophilic esterase was capable of engaging in continuous activity for a 5-day period while removing 76.23% of pigments from samples. It effectively and continuously eliminated BOD
