“…Additionally, an intensive post‐treatment separation process might be required to remove the leaked cells out of the contaminated effluent. [ 39 ] In this study, we further investigated the mechanical stabilities and structural stabilities of liquid beads by measuring geometries and characterization of compression behavior of liquid beads before and after treatment experiment.…”

“…[37,38] Meanwhile, phosphate ion is the primary inorganic phosphorus present in wastewater, readily incorporating into the cell bodies for metabolism process. [39,40] If untreated wastewater containing both ammonium and phosphate is discharged into water bodies, the environmental consequences from eutrophication could be catastrophic. Thus, tertiary nutrient removal treatment of wastewater is essential to effectively reduce ammonium and phosphate concentrations, minimizing the risk of eutrophication upon effluent discharge into the environment.…”

Liquid beads are core–shell particles with a liquid core and a solid shell. Calcium alginate liquid beads have been emerging as a promising platform for cell encapsulation. These beads have demonstrated their capability of encapsulating and culturing a wide range of human cells for tissue engineering. However, a significant research gap remains in the application of alginate liquid beads for encapsulating photosynthetic microorganisms. Herein, fast‐growing microalgae strain Chlorella vulgaris is encapsulated into calcium alginate liquid beads to facilitate the removal of nutrients from wastewater, minimizing the risk of eutrophication. Liquid bead‐microalgae systems are prepared, using different calcium ion concentrations as crosslinking ions. It has been thoroughly characterized for their morphologies, cell growth patterns, nutrient removal capabilities, and overall stability throughout the wastewater treatment process, with upflow anaerobic sludge blanket effluent as the wastewater model. The results indicate that the liquid bead‐microalgae system with the highest calcium ion concentration (5%) performs more efficiently, exhibiting a well‐formed crosslinking structure, leading to rapid cell growth with the highest cell density and the most effective removal of nutrients. The findings from this study provide valuable insights for future optimization and upscaling efforts in wastewater treatment systems based on calcium alginate liquid beads.

“…They are suitable for the mild hydrodynamic environment owing to the relatively weak cell-substrate adhesion. Exploiting the entrapping methods is recommended for microalgal immobilization since the better system stability for long-term operation; Leakage of entrapped or attached immobilized microalgal cells commonly occurs with a prolonged cultivation period [ 46 , 152 ], which may harm the ecosystem. Thus, determining the cause of leakage and discovering new materials for better fitting the microalgal immobilization demand is strongly encouraging; A limited number of contaminants have been investigated by employing the immobilized microalgal system [ 37 , 39 ].…”
