However, their commercial viability faces challenges, such as low CO₂ capture efficiency, sensitivity to environmental stresses, and high water and nutrient demands. This thesis aims to overcome these challenges by focusing on strain selection, optimizing cultivation conditions, ensuring CO₂ utilization stability, achieving high biomass productivity, cost-effective harvesting, and water reuse strategies.enThesis
