From Biomass to Efficient Lipid Recovery: Choline-Based Ionic Liquids and Microwave Extraction of <i>Chlorella vulgaris</i>.

ABSTRACT: The sustainable extraction of microalgal lipids represents a critical step toward the valorization of biomass for nutraceutical, pharmaceutical, and biofuel applications. In this study, a microwave-assisted extraction approach using a biocompatible ionic liquid (IL), [N_{1 1 2OH 2OH}][C₆H₁₁O₂], was investigated for lipid recovery from Chlorella vulgaris. Conventional methods (Soxhlet, Folch, and Bligh & Dyer) were first evaluated for benchmarking. Optimization of microwave power, extraction time, and algae-to-IL mass ratio demonstrated that a 1:8 (m/m) ratio under 5 min and 750 W microwave pretreatment achieved the highest lipid yield, with 10.61 ± 0.39% lipids recovered from the supernatant alone. Subsequent extraction of the p
