Enzymatic biodiesel production often faces challenges such as mass transfer limitations and enzyme sensitivity, resulting in low reaction efficiency. This study aimed to address these issues by integrating ultrasound technology with low-cost CO2-based alkyl carbamate ionic liquids (ILs) additives. Among the investigated ILs, N,N-diallylammonium N′,N′-diallylcarbamate (DACARB) demonstrated highest fatty acid methyl ester (FAME) content ultrasound-assisted catalyzed Eversa Transform 2.0 at an optimal temperature of 50 °C. The addition DACARB improved solubility immiscible reactants enhanced lipase stability, maintaining high FAME yields even under amplitudes up 100% duty cycles 20%. Enzyme hydrolytic activity assays revealed that activated lipase, increasing 33% through favorable alterations tertiary structure, confirmed fluorescence spectroscopy. Furthermore, employing a stepwise methanol dosing strategy 40% amplitude 5% cycle presence 2 wt % achieved 91.3 within 12 h, using only 0.2 concentration. highlights potential promising additive enhance efficiency enzymatic production, offering solution overcome current process.
