Synergistic Effects of Ultrasonication, Microwave, and Ionic Liquids on the Extraction of Biomolecules from Chlorella sp.

Year: 2026

Type: conference-paper

Abstract: Microalgae are promising biological resources for the production of proteins, carbohydrates, pigments, and other valuable compounds. Among them, Chlorella species have attracted considerable interest due to their rapid growth and suitability for multiproduct biorefinery. However, the highly recalcitrant cell wall of Chlorella limits solvent penetration and mass transfer, hindering the extraction of intracellular compounds (Alagawany et al., 2021; Yukesh Kannah et al., 2021). Although ultrasonication and microwave treatments have been widely investigated, their individual efficiencies remain limited (Guadalupi et al., 2025; Thanaraj et al., 2025). Ionic liquids can weaken cell wall structures, although their practical application remains limited by cost and viscosity (Hussain et al., 2025). Therefore, combining low-concentration ionic liquids with physical fields may provide an effective strategy for improving extraction efficiency while reducing energy consumption.
