Meanwhile, based on the unique properties of ultrasound, ultrasound technology, widely used in pharmaceuticals and materials synthesis, has shown exceptional mass transfer capabilities in adsorption and desorption, thereby greatly enhancing the performance of these two technologies. However, the mechanisms related to the combination of ultrasound with adsorption and desorption technology have not yet been thoroughly summarized.

Finally, ultrasound can significantly reduce the time required to reach adsorption equilibrium and increase adsorption capacity by accelerating mass transfer and modifying adsorbents.

The ability of microalgae to respond to different stress conditions tends to cause epigenetic changes that influence the bioenergy potential of microalgae. This comprehensive review delves into the importance of understanding these epigenetic changes in microalgae and how they can be manipulated to enhance bioenergy potential. The review shows how epigenetic changes in oxidative phosphorylation cause a change that affects cellular energy homeostasis and signal transduction pathways, leading to altered metabolic profiles and stress adaptation strategies.

The epigenetic change in this protein trigger a change in energy production and photosynthesis efficiency in microalgae, which are vital for the biosynthesis and accumulation of important metabolites useful for biofuel production.
