A CONCISE REVIEW ON IMMOBILIZED ENZYME-CATALYZED BIODIESEL PRODUCTION
The increasing demand for sustainable and eco-friendly energy sources has accelerated research on biodiesel as a promising alternative to conventional fossil fuels. Enzyme-catalyzed biodiesel production, particularly using immobilized lipases, has emerged as an efficient and environmentally benign approach due to its high selectivity, mild operating conditions, and reduced by-product formation. Immobilization techniques, including adsorption, covalent bonding, entrapment, and encapsulation, significantly improve enzyme stability, reusability, and catalytic efficiency, thereby reducing production costs and enhancing process feasibility. This review provides a concise overview of recent advancements in immobilized enzyme systems for biodiesel synthesis, highlighting various support materials, immobilization strategies, and reactor configurations. Additionally, the effects of key operational parameters such as temperature, pH, alcohol-to-oil ratio, and substrate type on biodiesel yield are critically discussed. Challenges related to enzyme deactivation, mass transfer limitations, and economic scalability are also addressed. Finally, future perspectives focusing on nanostructured supports, hybrid biocatalysts, and process optimization are presented to advance the commercialization of enzyme-based biodiesel production. This review emphasizes the potential of immobilized enzyme technology as a sustainable pathway for efficient biodiesel synthesis
